As a trusted seal manufacturer, Martin’s Rubber stock a range of punched, cut, extruded, sheet and fabricated products. We are a leading manufacturer, stockist and supplier of hydraulic and pneumatic rubber seals, including lip seals, with in-house production facilities using CAD/CAM processes.

What are rubber seals?

Rubber seals, rubber strip seals and lip seals join mechanisms or assemblies together to prevent leaks, and conform to a static or moving surface to contain pressure or exclude contamination. The efficiency of a rubber seal often depends on factors such as the housing design, surface finish of the mating components, correct design to deliver appropriate compression, and the correct choice of material for the environment in which the seal operates.

Rubber seal materials

In addition to custom moulded rubber seals, we have been supplying standard hydraulic cylinder seals and pneumatic rubber seals for over 20 years across all standard profiles and materials. The various materials of rubber seals we are able to offer include:

  • Polyurethane rubber seals (H-PU)
  • Nitrile rubber seals (NBR)
  • Viton® rubber seals
  • Silicone rubber seals
  • PTFE seals
  • Acetal seals (POM or Delrin)
  • Aflas® rubber seals
  • EPDM rubber seals

At Martin’s Rubber, we are also able to manufacture customised rubber seals and rubber strip seals, in the above-mentioned materials and can offer an ‘express’ service, whereby we are able to turn a rubber seal around within a very short lead time, in cases where machine or plant down-time is critical. We supply metal cased wiper seals and pneumatic piston seals, along with anti-extrusion or back up rings for high pressure applications.

Standard and bespoke rubber seals in stock

Rubber sealsIn addition to stocking all the common standard rubber O-rings, both imperial sizes to British Standard BS 1806, and metric sizes to British Standard BS 4518, in nitrile (NBR), silicone, EPDM and Viton®, we also have the facilities to supply non-standard materials such as HNBR and Fluorosilicone. We have been supplying seals to the construction plant and equipment market for many years through our ‘M.R. Quality Parts’ brand, creating hydraulic cylinder seal kits for popular construction plant machinery.

Similarly, we can offer pre-packaged sealing kits for repair or routine maintenance to customer specifications. We can also include dedicated branding as a consumable item or for spares, using our in-house kitting service.

Rubber seal experts

Our production, stockholding and kitting facilities enable the supply of both bespoke or standard hydraulic cylinder seals and pneumatic sealing components. Our seal stocking and machining complements the traditional moulded, extruded or punched products that we also manufacture for sealing applications. This unique combination of processes, all carried out in-house, enables us to offer a wide range of sealing solution products that are rapidly available, cost effective and of high quality. We produce hydraulic cylinder seals in all the common polymers and engineering plastics, in a range of materials from very soft to rigid, and with specialist grades which can confer properties such as:

  • High wear
  • High temperature
  • Explosive decompression resistance

With options to machine, extrude, cut or mould a rubber seal, there are very few applications that cannot be fulfilled with our range of sealing products.
