Stationary hydraulics cycle far more often than mobile equipment and tolerate far less leakage. We supply the valves, fittings and hose pipes that sit around your power pack, and we will tell you plainly where our range ends.
The highest-force circuit on the machine, and on a moulding machine or press the one that cycles most often. Impulse cycles, not burst pressure, decide hose life here.
ISO 18752 grade C / D · EN 856A 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.
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.
Repeated pressure spikes fatigue a hose even when its burst rating is comfortably adequate. A hose can pass a burst test and still fail on impulse cycles, which is why four-spiral construction exists.
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.
Assemblies built from one maker's hose and another maker's ferrule and fitting compromise coupling retention. Major manufacturers restrict their crimp data to their own combinations and disclaim liability otherwise.
Near moulds, curing presses and furnaces the binding constraint is temperature and fluid, not working pressure. Using an oil hydraulic hose where a steam or hot-water hose is required is a defined mis-specification, not a shortcut.
This is an orientation map, not a parts list. It shows which of our product families sit where on presses, moulding machines and machine tools, 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.

Levelling Pads & Anti-Vibration Machine Mounts
Not part of a hydraulic circuit, but the same machines sit on them. Machine feet that hold a machine tool, press or moulding machine level on an imperfect floor and keep its vibration out of the slab.
Explore Levelling Pads →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 test and inspection documentation where the order calls for it. Third-party inspection welcomed and coordinated.
Supply to approved drawing or sample, traceability through production, QA and pressure or dimensional testing before dispatch, and a clear statement at quotation of anything we cannot hold.
Dimensional consistency across batches, MOQ and price breaks stated up front, and full export documentation on every shipment.
Matched hose and ferrule pairings so retention is not left to chance, consistent inside and outside diameter so your dies keep working, and honesty about availability rather than an optimistic promise.
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.
ISO 4406 codes fluid cleanliness as three numbers, the particle counts per millilitre at 4 micrometres and above, 6 and above, and 14 and above. It matters more in stationary hydraulics than on mobile equipment because the components damaged by the smallest particles, proportional and servo valves, are usually the most expensive parts on the machine.
O-ring sealed families rather than tapered metal-to-metal ones. O-ring face seal to ISO 8434-3, which is based on SAE J1453, and the 24 degree cone with O-ring to ISO 8434-1 both seal on an elastomer rather than on thread interference. Tapered NPT or BSPT joints in a vibrating circuit are a chronic weep source.
By impulse grade, not by burst pressure. ISO 18752 defines grades A to D by impulse cycles at a stated temperature and impulse pressure, with grade D requiring over one million cycles at 120 degrees Celsius at 133% of maximum working pressure. That is the honest way to specify a press or moulding machine circuit.
Not where the service is steam or hot water. That is a separate hose family with its own standard, EN ISO 6134, and its own tube elastomer. Using an oil hydraulic hose in that duty is a mis-specification. Tell us the ambient and fluid temperature and we will confirm which family applies, or tell you if we do not supply for it.
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.
No. JIC to SAE J514 and ORB to SAE J1926 share the same UN/UNF thread form but seal completely differently. JIC seals on a 37° metal cone; ORB seals on an O-ring compressed against a machined boss face. Assembling one into the other will not seal reliably and can damage the port.
Yes, this is one of the most common requests we get. Imported machines bring BSP, metric 24 degree cone, JIC, ORB and NPT into the same shed. Adapters and reducers across those families are a core part of what we supply. Send the port standard on both sides and the pressure rating.
Where a plant runs a formal maintenance system, DIN 20066 practice is the usual reference: bulk hose no more than four years old at assembly, and assemblies not in service beyond six years from date of manufacture, of which storage should not exceed two years. Condition-based replacement should override that where the duty is severe.
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.
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.
