Cork Gasket Manufacturers
Known for sealing bottles, cork is a highly water-resistant material with excellent resilience and durability making it a useful gasket material. Cork can withstand high levels of vibration and abrasion, so it is often used to seal between pipes and around covers. Our cork gaskets can be cut in any size and thickness, with bespoke gasket shapes available.
Properties of Cork
Cork is an excellent material for gasket manufacture due to the following properties:
- Highly Water-resistant and hydrophobic
- Durable
- Lightweight
- Flexible
- Oil-resistant
- Ozone-resistant
- Fire-resistant
- Closed-cell structure
- Good compression set resistance
- Hardness shore A 60-80
- High Density 700kg/m3
Rubber-bonded cork also shares the properties and characteristics of the rubber used. A cork and rubber gasket material can be extremely beneficial for use in automotive, electrical and marine environments. Cork also floats in water, making it useful for marine work.

What is a Cork Gasket?
A gasket is a seal designed to fit between two surfaces, for example at the join between two pipes, to prevent leaks from inside. They are also known as o-rings or washers, though gaskets typically have additional holes for bolts or screws to pass through. Cork gaskets are made from cork, or a cork and rubber mix, providing a hydrophobic (water-resistant) and durable substance perfect for sealing.
What can Cork Gaskets be used for?
Cork gasket materials are effective and relatively affordable seals, with good oil and water resistance. These properties make cork gaskets effective in the automotive industry, among others. Uses include:
- Sumps
- Fuel and oil pumps
- Gearboxes
- Inspection doors
- Valve covers
- Electrical transformer gaskets
- General cover and lids
- Electrical switchgear
- Anti-vibration padding
- Cork is ideal for sealing irregular surfaces or joins with uneven bolt loading due to its good compression properties.
What are the main features of Cork Gaskets?
Cork is an excellent material for gasket manufacture due to the following properties:
- Highly Water-resistant and hydrophobic
- Durable
- Lightweight
- Flexible
- Oil-resistant
- Ozone-resistant
- Fire-resistant
- Closed-cell structure
- Good compression set resistance
What grades of thickness can Cork Gaskets be supplied in?
We cut cork to thicknesses ranging from 1mm to 60mm, working to tight tolerances.
Are Cork Gaskets environmentally friendly?
Cork is a natural substance and part of the bark of Cork Oak trees. Harvesting cork does not harm the trees, as it regrows over 9-12 years, and cork biodegrades completely when its life cycle is finished. Depending on whether the cork is bonded with resin or rubber, cork gaskets can be a sustainable and eco-friendly gasket choice.
