OEM Hose Assembly Replacement
OEM hose assembly replacement, from the old part
When the manufacturer stopped making it, or wants six weeks and a painful number for it, the assembly still has to come from somewhere. Bring in the original and we work backwards from it. Discontinued brake tubes, forty year old air conditioning lines and machinery nobody supports anymore are ordinary days at this counter.
Discontinued, superseded into nothing, or the manufacturer is gone entirely. There is no part number left to order, so the assembly gets rebuilt from the sample instead.
The dealer can supply it eventually, for several times what the components are worth. Same assembly built here, usually the same visit, usually for a fraction of it.
How It Works
Working backwards from what you bring in
There is nothing mysterious inside an OEM hose assembly. It is a length of hose with a fitting on each end, chosen for a pressure, a medium and a routing. The part number is a label the manufacturer put on that combination, and losing the label does not lose the combination.
What we take off the original is the thread standard and size at each end, the seat angle, whether an end swivels or is fixed, the orientation of one end relative to the other, the overall length measured across the fittings, and the hose construction itself. Between those, the assembly is fully described, and none of it requires the manufacturer's cooperation.
Sound end fittings often go straight back onto the new hose, which matters most when an end is genuinely unusual. A proprietary block, an unusual flange or a fitting that mates to something specific on the machine gets reused rather than substituted, and only the hose and the ferrule are new.
Where the original is a hard line rather than a hose, tube can be bent and flared to match a sample. Customers bring in brake tubes their manufacturer stopped producing and leave with copies. That is the same principle applied to a different material.
Triage
Can we match yours?
Two or three questions and you will know what to bring and whether it is worth driving over today.
Do you still have the old assembly?
Even a badly damaged one is useful. What matters is whether the physical part is in your hand or in a skip.
Are both end fittings still intact?
Intact enough to measure a thread and see a seat. Scorched, bent or corroded is usually still fine. Missing or destroyed is not.
Can you get to the machine to check the ports?
Photographs of the two ports the line connects to, and the make and model of the equipment.
Bring it in. Most of these leave the same visit.
With the assembly in hand and both ends readable, everything needed to rebuild it is already on the counter. Thread standard, seat angle, orientation and length all come off the original, and sound ends frequently get reused on the new hose.
Take a photo of the routing before you removed it if you still can, because a hose that measures correctly can still fight you if the clocking is wrong. Then walk into whichever counter is closer, no appointment needed.
Bring photos and the machine details.
Without a complete original we work from the ports instead. Clear photographs of both connection points, the make and model of the equipment, what the line does and roughly how it routes will get us most of the way there.
Expect this to take longer than a straight match, and there is a reasonable chance of one return trip to confirm a fitting. It is still considerably faster than waiting on a discontinued part number.
Ring the counter before you drive over.
With no part and no access to the machine, this becomes research rather than measurement. Sometimes an original part number, a service manual diagram or a photograph from a parts listing is enough to identify what the ends were. Sometimes it is not.
Call and describe what you are dealing with. Somebody will tell you honestly whether it is worth the trip, which is more useful than finding out after you have made it.
What Comes In
The parts nobody else will touch
These are the jobs people arrive with after the dealer said no and two suppliers said the same thing.
Air conditioning lines
A/C hose on vehicles well past support, where the original assembly used a crimped block that is no longer available separately. The block gets reused and the hose replaced. Regular work on restorations.
Brake and clutch lines
DOT rated hose and hard tube, copied from the old part when the manufacturer stops production. Customers bring in brake tubes their maker discontinued and leave with matched copies.
Power steering for engine swaps
A swapped engine leaves a pump from one vehicle and a rack from another, so no catalog covers the line between them. Built as a single assembly rather than a stack of adapters.
Obsolete equipment circuits
Presses, lifts, balers and machine tools still earning their keep decades after the maker stopped supporting them. The hydraulics are entirely rebuildable even when the machine is not supported.
Steering and fuel fill
Older hulls with steering and fuel systems from manufacturers long absorbed or closed. Stainless ends available where corrosion has already claimed the originals.
Mixed and aging fleets
Vehicles and equipment from several eras, where holding OEM stock for every one is impossible. Standardising them onto common builds is usually cheaper than chasing part numbers.
Straight Answers
What matches easily, and what does not
Almost everything is buildable. A few things genuinely are not, and it is better to know which is which before you make the drive.
- Standard threaded ends in any combination, including mixed imperial and metric
- Unusual lengths and routings that no catalog assembly covers
- Assemblies where the ends are sound and only the hose has failed
- Hard tube copied from a sample, including brake and fuel lines
- Proprietary end blocks that can be cut off and reused
- Anything where the original is in your hand and readable
- Assemblies with integrated sensors, switches or wiring moulded into them
- Ends permanently moulded into a component that cannot be separated
- Parts where nothing physical survives and no diagram or number exists
- Anything requiring a manufacturer certification we cannot issue
- Very large bore assemblies at short notice, which need a call ahead
- Building an assembly from a drawing rather than a sample is custom hose fabrication
- Identifying an unfamiliar thread standard is covered on custom hose assembly
- Pressure class and construction sit on hydraulic hose assemblies
- If the machine is down right now, start at emergency hose repair
Before You Come In
Common questions
In most cases it is better, because hose compounds have improved considerably over the decades and the replacement is new rather than thirty years old. What matters is that it is built to the same pressure, the same medium compatibility and the same routing, which is exactly what gets taken off the original.
Usually yes, and that is the most common way people end up here. A dead part number changes nothing about the physical assembly. Bring the old one in and it gets measured and rebuilt without any reference to the catalogue it fell out of.
Often, and on an obsolete assembly it is frequently the whole point. Reusable and field attachable ends come off and go back on by design. A permanently crimped ferrule cannot be recrimped, but the fitting body it holds can sometimes be salvaged and a new ferrule used. We will tell you which situation you are in when you bring it in.
Brake assemblies get built from DOT rated hose and correctly rated fittings, which is the standard that applies to the components. What we cannot do is issue a manufacturer certification for a vehicle, and if your application requires one, that has to come from the party entitled to issue it. Tell us what the assembly is for and we will be clear about what we can and cannot supply.
It varies too much to put a number on, because it depends entirely on what the dealer charges for that part. What customers consistently report is that the gap is large and the wait is the bigger difference. One review on our profile describes two hydraulic steering hoses at thirty percent of the marine dealer price, against a two week wait.
Yes, and on obsolete equipment it is the sensible move. Once an assembly has been rebuilt here the specification stays on file, so the second one never needs the original again. For fleets running several of the same machine, having a spare set built at the same time avoids repeating the whole exercise. Ask at either counter or through the contact page.
Get It Matched
Bring in the part nobody makes
If it can be measured it can be built. Walk into either counter with the original, or send photos and the machine details and we will tell you straight whether we can match it.
