Loader, remote, hitch and implement circuits all run off the same pump, and all fail at the worst possible week. We supply the valves, fittings and hose pipes that sit in them, and we are clear about where our range ends.
The hardest-worked circuit on a utility tractor, cycling all day with the boom flexing under load. Two-wire braid is the usual construction, with routing along the loader arm the main wear point.
EN 853 2SN · SAE 100R2ATA person reads it, not an auto-responder. If it is something we can supply well, we say so and quote it. If it sits outside what we do, or if we cannot hold the specification you need, we tell you that plainly and up front rather than stretching to fit, and where we can we will point you toward a better route. You get a straight answer either way, within one business day.
None of these are random. Each has a mechanism, and each has a standard that tells you how to specify against it.
Hose rubbing on hose, on structure, and on the ground. Once the cover is breached the reinforcement corrodes and burst follows, usually well before the assembly's rated life.
Every hose change in the field is an ingress event. Particles at 4 µm and above attack proportional and servo elements; 6 µm and above accelerates pump and cylinder wear.
BSP and NPT share the same 1:16 taper but different thread form angles, 55° against 60°. In many common sizes they screw together and look correct, then leak under pressure. BSPP seals on a bonded washer against the port face, not on the threads.
Agricultural push-to-connect couplers and flat-face couplers are separate standards. A new implement and an older tractor frequently cannot be joined without an adapter, which is why adapters between the two are a stocked product in their own right.
Biodegradable hydraulic fluids are not one thing. ISO 15380 defines four families, and one of them, HEPG, is explicitly incompatible with paints, sealing materials, hoses and most other hydraulic oils.
Rubber ages whether or not the machine runs. Bulk hose sitting in a workshop and assemblies fitted to seasonally used equipment both quietly pass their service life.
This is an orientation map, not a parts list. It shows which of our product families sit where on tractors and farm implements, so you can see quickly whether your requirement is one we can serve, and where it is not.
We work to your specification. Send the size, material, thread standard, pressure rating and quantity, or a drawing or sample, and we confirm everything in writing before production. If we cannot hold what you need, we will say so rather than guess. Ratings and sizes referenced anywhere on this site are typical reference values.
Published so you can check a specification without calling us. Where your requirement names one of these, quote it in your RFQ and we will confirm against it, or tell you if we cannot.
Confirmed specification before production, consistent construction across repeat orders, and MOQ and price breaks stated up front so you can plan a season's stock rather than react to it.
Supply to approved drawing or sample, traceability through production, and QA and pressure or dimensional testing before dispatch. Where a requirement is beyond what we can reliably hold, we tell you at quotation, not after.
RFQ response within one business day, a defined spares list per machine type, and honesty about lead time rather than an optimistic date that slips.
IEC-registered export handling, ISO 9001:2015 quality system, full export documentation on every shipment, and third-party inspection welcomed and coordinated on any order.
We supply hydraulic valves, fittings and hose pipes. Where your requirement sits inside that, we would love to take it on, and we will tell you exactly what we can hold and what we cannot.
Where it sits outside, you will hear that from us up front, not three weeks into a quote. And if you want, we will point you toward a route that is more likely to work. No pitch attached to that answer, and no hard feelings if you come back later.
Not an auto-responder chain, and not a queue.
Including the answers that are a no.
What we can hold, and what we cannot, in writing.
NDA on request, handled with discretion.
Two-wire braid to EN 853 2SN or SAE 100R2AT is the usual construction for loader lift and tilt. What matters as much as the construction class is the routing: the loader arm flexes constantly, so abrasion cover condition and correct clamping usually decide the life of the assembly. SAE J1273 covers that routing and clamping practice.
It depends which biodegradable fluid. ISO 15380 defines four families, HETG, HEPG, HEES and HEPR. HEPG in particular is explicitly incompatible with paints, sealing materials, hoses and most other hydraulic oils, so the inner tube and seal elastomer have to be matched to the fluid. Name the fluid family in your RFQ and we will confirm compatibility, or tell you if we cannot supply for it.
ISO 5675 is the agricultural general-purpose quick-release coupler, a push-to-connect design that is breakaway capable, long established on tractor rear remotes. ISO 16028 is the flat-face family, common on newer and European implements and preferred where contamination control matters. They are separate standards and will not mate directly, which is why adapters between the two are sold as a product in their own right. Tell us which family is on both sides of your connection and we will confirm what we can supply against it.
Two common causes. Field dust entering the coupling face at every connect and disconnect, which scores the seal, and residual pressure trapped in the implement circuit making a clean reconnection impossible. Dust caps and clean disconnection practice fix most of it. ISO 4406 explains why the dust matters, the same particles that score a coupler seal also wear the pump.
Both are tapered at the same 1:16 rate, but the thread form angle differs, 55° for BSP and 60° for NPT. In several common sizes they will screw together and appear correct, then weep under pressure because contact is incomplete. BSPP, by contrast, is a parallel thread that seals on a bonded seal against the port face, so without that washer it will not seal at any torque.
Beyond the usual abrasion and impulse fatigue, agriculture adds three things: crop residue and mud packing around trailing hose bundles, year-round UV and ozone exposure on machines parked outdoors, and long idle periods where the rubber ages while the machine does not run. That last one is why DIN 20066 age practice bites hardest in agriculture.
Where the requirement is defined, yes. We need the hose construction class, length, both end types and the thread standard on each. Hose, ferrule and fitting should come from one matched series at the correct crimp diameter, because mixing brands compromises coupling retention.
Yes, and that is the normal route. Share a drawing, a specification or a sample and we confirm dimensions, material, thread standard and pressure rating in writing before production. Where a requirement is beyond what we can reliably hold, we say so at that point rather than after the order.
Directional control valves and the relief, check and flow control valves around them are within what we supply. Send the spool configuration, flow rate, port sizes and thread standard you need and we will confirm what we can hold against it.
Tell us anyway. We supply hydraulic valves, fittings and hose pipes. If your requirement sits inside that we would like to take it on, and we will tell you exactly what we can hold and what we cannot. If it sits outside, you will hear that from us up front rather than three weeks into a quote, and where we can we will point you toward a route more likely to work.
Size, material, thread standard, pressure rating, quantity and destination country, or simply a drawing or sample. If it is something we can supply well we will quote it. If it is not, we will tell you that instead, and point you somewhere more useful where we can.
