Cork Gaskets Manufacturing Experts

Cork gaskets and cork rubber gaskets are suitable for industrial applications because of their ability to withstand moisture, extreme temperatures and pressure without degrading. 


They may also offer sound deadening and anti-vibration in some industrial settings, adding to their versatility and appeal.


At Munch & Co., we stock several cork gasket types for many industries, including: 

  • Automotive engineering
  • Transformers and generators
  • Power supply applications

Common use cases include electrical switchgear, covers and lids, valve covers, sumps, crankcase covers, inspection doors, and anti-vibration.

Simply give us a call or fill in the enquiry form below and one of our experts will give you all the advice and guidance to meet your cork or paper requirements.

Our Range of Cork Gaskets

Our Range of Cork Gaskets

Here is a list of our cork gaskets of different grades and sealing applications. These are available as natural cork, resin-bonded, or rubber bonded. Click on the links below to download a data sheet on the different grades.

Nitrile-bonded cork is a potent, general-purpose gasket material with a speckled appearance, suitable for a wide variety of applications, including heavy plant machinery, valve covers, and oil pumps. It has a tensile strength of 1.38Mpa and a compressibility of 35 to 45% at pressures of 400 PSI. Recovery after compression is 75% and volume changes after immersion in oils are -10 to +5% for some compounds..

Neoprene rubber cork gaskets are highly compressible, making them ideal for situations involving low- to medium-bolt pressures. Neoprene-bonded cork rubber has a tensile strength of 17.5 PSI or 250 kg/ sq. cm and a compressibility of 25 to 40% at 44 PSI. Recovery is around 75 per cent with minimal cracking, making it a sensible choice as a gasket material.

Statite oil paper is a type of paper that is resistant to oil and fuels. As such, it has similar properties as rubber, making it ideal for automotive applications and water pumps. The material has a tensile strength of 13.0 N/mm2 and a 12 to 16% compressibility. Oil weight increase is less than 15% and thickness increase is less than 5%.

Flexoid gasket paper is affordable and has excellent oil and fuel resistance. Tensile strength is 13.79 Mn/ Sq. m and an oil weight increase of 15%. Industrial users typically choose this type of paper for its affordability.
Firm-grade NPR cork gaskets are manufactured to be stiffer than their regular counterparts while still offering the exceptional vibration isolation of regular cork. We recommend this type of cork for medium- to high bolt pressures because it is flexible and resilient. NPR cork gaskets supplied by us have a tensile strength of 15 kg/cm in the transversal direction, and 22.5 kg/cm in the longitudinal direction, compressing between 20 and 35% under 400 PSI. Compression does not result in cracks in the material, as it does in some products. This makes the rubber/cork material suitable for automotive and industrial gaskets.
