Cork-Elastomer Jointings are suitable for many fluid sealing applications in the automotive, engineering and electrical industries. Cork-Rubber products hold up well under external environmental conditions and have the advantage of minimal side flow compared to most rubber materials and generally possess better load distribution across the sealing faces.
The majority of grades available utilise either Nitrile or Neoprene as the blended rubber binder; other blends, such as Silicone and cross blends are available for specific process duties and cover obligatory industry specifications. Our sales office will appropriately recommend the most effective material where such specifications are requested.
Most grades retain
flexibility down to -25OC and can withstand maximum
operating temperatures in liquids up to 110OC. The
‘Chemical Suitability Guide’ below is intended only as a
guide as the possible effect of elevated temperatures needs
to be considered when determining the compatibility of
these products with a given chemical.

OP (Oil & Petrol) Paper Jointing is an economical cellulose fibre-based material impregnated with a glue glycerine composition, or plasticised gelatine depending on the grade. It is predominantly used in the automotive industry as a gasket material for carburettors, fuel and oil pumps, gear casings and pipeline flanges. It has excellent resistance to fuels, oils and most organic solvents and is ideal for use at low bolt loadings.
It has a maximum operating pressure of 8 to 10bar (depending on grade) and an operating temperature range of -20OC to 120OC; limits of pressure and temperature should not be used simultaneously and are dependant on the thickness of the gasket. Supplied in either sheet/roll or precision cut gaskets (maximum 1m wide) from 0.15mm, 0.25mm, 0.4mm, 0.5mm, 0.8mm, 1mm, 1.2mm, 1.6mm, 2mm or 3.2mm thick.
Engineering Felt is available in varying thicknesses, hardness and densities in both woollen and synthetic grades. It can be supplied in sheet, strip or cut shapes for anti-vibration, sound & shock absorption, dust seals, oil seals, wipers, polishing pads/wheels, filters and gaskets. Wool felts are used for wiping because their non-fray homogeneous structure maintains constant performance during wear life and they can carry a liquid layer and distribute it evenly.
They are used for polishing because they are tough and resilient, wearing in such a way that the working surface is constantly renewed. Because of their homogeneous structure wool felts make excellent filter media accommodating high flow rates whilst offering good particle collection efficiencies. Long lasting resiliency under load offers application suitability, in vibration isolators, padding & cushioning, shock absorption and gaskets.
