Take Hydraulic Hose and Fittings Orders for Assemblies You Can Build

The line item is a build ticket, not a SKU. A hydraulic hose assembly is a hose spec, an inside diameter in dash sizes, a cut length, an end A, an end B, the angle between two elbows, and often a sleeve or spring guard. Multiply your hose line by your fitting line by every length a customer might want and you do not have a catalog. You have a combination space no variant table can hold. So hose sites tend to offer a picker that starts at the hose ID and leaves everything after it to a phone call.

Some of those combinations must not be orderable at all. Each hose manufacturer publishes crimp specifications for its own hose and its own couplings, and treats mixing as a decision it has to sign off. One manufacturer's industrial hose guide puts it plainly: "No substitutions should be made unless written authorization has been given by the hose manufacturer, coupling manufacturer and the end user." A storefront that lets a buyer put one maker's ends on another maker's hose has sold an assembly with no rating behind it. Your crimper operator catches it, if you are lucky, after the order is already promised.

An assembly is rated to its weakest part. The SAE J517 hydraulic hose standard covers assemblies built from J517 hose and connectors per SAE J516, J518 or J1453. Their maximum working pressure "shall not exceed the lower of the respective SAE maximum working pressure values." ISO 18752 says the same thing for its own hose classes, where each class carries a single maximum working pressure for all sizes. So a 100R2 hose on the right ends is not automatically a 100R2 assembly. The rating that matters is the lowest one in the build, and the buyer should see it before they order.

Selection starts with STAMPED, and the last letter is yours. Size, temperature, application, material or media conveyed, pressure, ends, delivery. The same guide defines delivery as "Identify the number of items and when they need to be supplied." Six of those letters are engineering questions the storefront has to ask in order. The seventh is a commerce question: how many, and by when. The storefront should answer it at the moment the buyer is choosing, not in a follow-up email.

End connections are a vocabulary, and buyers use it loosely. JIC 37 degree flare under SAE J514, O-ring face seal under SAE J1453, NPTF and NPT pipe threads, BSPP, SAE O-ring boss, metric DIN. A technician asks for a dash 8 JIC female swivel. A maintenance planner asks whether the port on the machine is JIC or SAE. The storefront has to understand both, and filter ends to what the chosen hose can actually take.

Repeat business arrives by the customer's part number, from a van. The mobile hydraulic repair tech is standing at a machine with a burst hose and wants the same assembly as last time. The plant planner reorders a dozen assemblies every quarter under their own number, not yours. The counter writes tickets by hand for walk-in contractors. Industrial hose adds a different set of questions again, because food, chemical and steam service turn on the material conveyed as much as the pressure.

The assembly is configured, then priced through Uncap Quotes. A hose assembly is a hose spec, an inside diameter, a cut length, two end fittings, an orientation and a protective sleeve, each with its own price for the account. The assembly configurator and the crimp compatibility rules behind it are built during implementation. Pricing runs through Uncap Quotes, which handles configure, price, quote inside the Shopify admin, with negotiated account prices, tiers and volume breaks applied automatically. The buyer builds the assembly step by step, and the price comes together from hose by the foot, both ends, the sleeve and your crimp charge.

The rules come from your crimp tables. Which fitting series crimps onto which hose family, at which dash sizes, is loaded from the manufacturer crimp data you already work from. That compatibility logic, crimp spec validation and the calculation of assembly rating as the lowest component rating are built during implementation, against your line card. Minimum and maximum cut lengths for each hose size belong to the same rule set. Once they are live, the storefront only offers ends that can be crimped onto the chosen hose, at a length your shop will actually cut. A buyer who enters an application pressure above the assembly's rating is told so before checkout, not after the ticket reaches the crimper.

On the question of whether Shopify can handle engineering-grade configuration. The crimp validator is a rules engine designed and built from your data during implementation, so the real decision is where that logic lives and whether account data reaches it intact. The failure mode on any B2B build is an integration written for retail that does not map company accounts, catalogs and contract pricing correctly. Uncap Connect is embedded inside Shopify rather than running as separate middleware. It keeps Shopify and your ERP in real-time, two-way sync, so inventory on the reel and in the bin stays current. It also syncs "customer-specific pricing, credit terms, and tax rules." The ERP stays the system of record.

Non-standard builds go to a quote, not a dead end. Large bore hose, unusual ends, test requirements or a fleet program price belong in a quote. Uncap Quotes sends exceptions to the right approver, and every quote carries a validity window and a full revision history. When the buyer accepts, the approved version converts to a Shopify order in one click. The buyer who started in the configurator does not have to start again on the phone.

The same assembly, reordered by the customer's own number. In Uncap Portal, each buyer sees their own assortment and pricing, with reorder lists and order history a click away. The assemblies a planner buys every quarter sit on their reorder list. A customer part number cross-reference, so their number resolves to your build spec, is built during implementation.

Exploded views for the machines you service. Some of your trade is replacement hose for specific equipment. For that, Uncap Diagrams puts clickable hotspots mapped to live SKUs on the machine's exploded view, so the tech adds the exact part without a part number. Mapping each hose position to the assembly that fits it is configured during implementation.

Proof, labeled at its true distance. Uncap has not yet published a hose and fittings case study. The closest published builds are adjacent industrial distribution. ULE Group "moved its catalog of over 250,000 SKUs onto a Shopify B2B storefront built by Uncap." It runs "a real-time Epicor ERP integration" that "syncs inventory and pricing," plus "a cart-level convert-to-quote feature for high-value purchases." WeldingStore operated "for more than half a century" serving welders and technicians before Uncap built its B2B ecommerce site from the ground up. Sanitaire sells commercial cleaning equipment "through a B2B distributor model," and Uncap migrated it to Shopify Plus with its ERP integrated.

Hose assembly configurator. Hose spec, inside diameter, cut length, end A, end B, orientation and sleeve, built during implementation and priced through Uncap Quotes for the logged-in account as the buyer builds.

Crimp compatibility gating. Ends filtered to the fitting series your crimp data approves for the chosen hose family and dash size, within the cut lengths you allow, so a mixed-brand or non-crimpable build cannot reach the cart.

Assembly rating shown before checkout. The working pressure displayed is the lowest of the hose and both ends, checked against the application pressure the buyer enters.

STAMPED order of questions. Size, temperature, application, material conveyed, pressure and ends asked in sequence, with quantity and required date captured as part of the same flow.

Contract pricing on every component. Hose by the foot, each end, sleeve and crimp charge resolved from the ERP for the account, never a public list price.

Customer part number reorders. A planner's own assembly numbers mapped to your build spec during implementation, reordered from order history or a reorder list.

Quote path for specials. Large bore, special ends and program pricing handled as quotes with approval routing, validity windows and a full revision history, converted to a Shopify order in one click.

Diagram ordering for serviced equipment. Clickable hotspots mapped to live SKUs, so a technician adds the exact part without a part number, with hose positions mapped to assemblies during implementation.

ERP sync without separate middleware. Pricing, inventory, customers and orders kept current between Shopify and the ERP, delivered through an owned Uncap Connect app or a managed iPaaS integration.

The honest line between product and build. The configure, price, quote workflow, account pricing and one-click order conversion ship in Uncap Quotes. The assembly configurator, crimp validation, assembly rating logic and part number cross-reference are built during implementation from your data. You see which is which in the scope, not in week six.

Built for the account, not the anonymous shopper. Account pricing, reorder lists and quote approvals all run inside Shopify, so the configurator, the counter and inside sales price the same assembly the same way.

Credentials you can check. Uncap is a Shopify Platinum Partner, on Shopify since 2013, with 380+ unified storefronts launched on Shopify.

Scoped before it is built. The Uncap Blueprint maps your hose and fitting line card, crimp compatibility tables, pricing model and ERP integration before any build begins. You keep the architecture, the prototype, the data plan, the risk register and the fixed-cost estimate, whoever builds it.

This page sits under industrial supply and MRO ecommerce, which covers punchout into Ariba and Coupa, catalog search at scale, vending and blanket orders for plant accounts. This page goes one level down, into the assembly that is built to order. For how the components of an assembly should be presented to a buyer, see the field notes on a bill of materials on Shopify. If your hose shop also sells replacement parts for the machines it services, see machinery and equipment parts. If your counter serves mechanical contractors, see plumbing, HVAC and mechanical supply. If your service trucks run to farms, see agriculture and farm supply. For the ERP side, see the Epicor Prophet 21 integration, the Infor SX.e integration, or the full list of ERP integrations.

Bring two documents: the crimp chart your shop works from, and a week of assembly tickets from the counter and the service trucks. Between them they hold the compatibility rules, the pricing and the reorder pattern this build has to reproduce.

Book a strategy session with Uncap, or start with a Blueprint if what you need first is the configurator logic and ERP mapping written down and costed.
