The right fitting for a reliable hydraulic connection
Fittings are the small components that make a hydraulic system work reliably — connecting hoses, pipes, cylinders, valves and pumps, and keeping a joint sealed under pressure. The wrong fitting, or a worn or damaged one, can cause leaks, poor performance and avoidable downtime.

RS Hydraulics Ltd supplies hydraulic fittings, adaptors, couplings and seals from Colchester, backed by over 45 years of experience in hydraulic engineering. Bring us the details of your connection, or the fitting you need to replace, and our team will help you find a suitable match.
Fittings for hoses, cylinders and systems
Our range covers the fittings that support the systems we repair and supply: hose fittings and adaptors for hose assemblies, couplings and seals for cylinders and rams, and pneumatic fittings and pipework where a system needs them. Because we also repair rams and cylinders in our own workshop, we understand how a fitting needs to work in practice, not just on paper. Fittings connect a hydraulic power pack to the system it serves.
If you are replacing a fitting, tell us the hose or component it connects to, the thread and size where you know it, and the application it is used in. Where a fitting is worn or obsolete, our team can advise on a suitable alternative.
A range of fittings, adaptors and seals
​Hydraulic adaptors, couplings, seals, hose fittings and pneumatic fittings and pipework, supplied alongside hose assemblies, cylinders, valves and hydraulic oils.
​Precision engineering for a proper fit
Our fully equipped workshop includes lathes, mills and surface grinders, and we offer bespoke fabrication and precision engineering. That workshop support helps where a standard fitting needs checking, or a component needs to be made to suit.
