oil seals

We hold a large number of British Standard Tools for o-rings and grommets and can mould in a range of materials and shore hardness's.

MRM have a dedicated production cell for low volume mouldings so are able to offer very low volume special o-rings, leveraging minimal tool cost options wherever possible.

Moulded Rubber Seals (Customer designs)

We also supply a complete range of :

oil seals


Customers often ask, " what is the service life of this seal ?" This is a difficult question to answer and depends on a number of factors, such as the type of fluid or chemical it is sealing against; the temperature of the service environment; whether the seal is static or under dynamic flex conditions; the sealing pressures involved; and most importantly- the attention and care given during the installation and flange tightening procedure.

The degree of compression necessary to achieve a leak free seal is dependent on the internal pressure and temperature of the fluid stream; the parallelism of the flange surfaces; the design of the seal area (machined groove, perimeter backing ring; or smooth flange); and the composition of the flange and piping (metal or resin/fibreglass). For most seal applications, a maximum deflection in the gasket thickness of 25% is recommended.

We can offer competitive tooling and short delivery times, moulding in range of materials material-data
