Hose assembly spec requests, read from the customer's words into a draft your assembler can check.

Hose requests come from people in the middle of fixing something. A planner sends a list, a fleet manager forwards a photo, a millwright types what he can read off the old hose. Somebody at your counter turns that into an assembly: hose type and size, the pressure and temperature it must see, what runs through it, both end fittings and how they line up, and the length.

For the test, AI reads copies of those requests and drafts the spec using the fields your bench works from, with each value marked by where it came from: the customer's words, something legible on the hose, or a record you sent. Any field the description can't settle stays open. It picks no hose and no fitting, and it never says a substitute is safe. A qualified person on your team checks every spec.

Size looks settled until you check the column. Hoses are counted by inside diameter in sixteenths, so a -6 is 3/8 inch, while tube goes by outside diameter. One published size table gives that same -6 a 5/16-inch bore on transportation and refrigerant hose. The layline normally clears it up, printing the maker, part number, dash size, working pressure in MPa or PSI, the specifications met and a date code. When a layline is painted over or worn off, one sizing guide says the old hose has to be cut and its inside diameter measured. A worn layline therefore goes on the draft as an open line for your bench, never a guess.

Length and angle each have more than one reading. A stated length can be overall, seat to seat, or the cut length before fittings. One component maker's sheet measures female ends nut to nut, O-ring face seal and flange ends seal face to seal face, and elbows to their center, while a published request form has the customer circle nut to nut, face to face or centre of angles. Orientation might arrive as degrees clockwise from a far-end fitting held at zero, with 270 as one maker's example, or as a clock reading such as 5:00. The draft keeps the customer's method beside the number and asks when two elbows come with no angle at all.

Standards say what an order holds, and what the rating can be. SAE J1754/3 covers procurement and ordering information for assemblies built from J517 100R hose and connectors under J516 or ISO 12151, and its scope stops at petroleum based hydraulic fluids, so a request naming another fluid sits outside that document. SAE J516 says an assembly's rated working pressure can't go above the lower of the hose's and the fitting's ratings, so the draft keeps a field for each. SAE J1273 gives recommended practices on selection, routing, fabrication, installation, replacement, maintenance and storage. We name them by title. The draft applies none of them, and nothing here is engineering advice.

Public buyers and equipment makers write their own lines. Tulsa's 2023 worksheet prices hose by the foot beside a separate labor cost and a manufacturer name and part number column. It keeps 100R1AT, 100R2AT, 100R12, non-conductive 100R7 and DOT 100R5 on their own lines, and writes an end as #10 hose by #8 NPTM. A refuse truck body maker's January 2021 service bulletin, on file with NHTSA, moved certain pump-to-valve lines from 2-wire braid to 4-wire spiral hose with a 4,000 PSI minimum working pressure. The same bulletin says crimp fittings are specific to the brand and model of hose and that some units may need a different length than the hose coming off. So the old hose is a starting point, and the draft says so.

What your reviewer will watch. Many counters work from STAMPED: size, temperature, application, material flowing through, pressure, ends, and delivery needs such as testing and certification. Did each one land on the draft as a stated value or an open line? Did the draft copy what the customer wrote instead of filling in a likely number? One published form leaves the crimp spec for the hose assembler and has staff verify and sign, and the draft leaves those blank too.

When your reviewer says yes against the success criteria, new requests go through the same drafting for about 30 days.

A qualified person checks every spec and approves each one before it posts anywhere or reaches the bench.

That month carries a fixed price, shown before you sign. Anything beyond it gets priced as its own job, and monthly support can follow.
