Types of Gaskets we supply

Below, we will explain about the different materials that we supply and manufacture gaskets from, and applications that they are most suited to.

Click on the buttons below each category to find out more.


Designed for low pressure sealing applications. Rubber seals compress easily and can be used with a wide range of liquids and gases.

Depending on polymer style, rubber has a wide temperature range of between -70° and + 250° C.


We carry a wide selection of polymers from 0.75mm to 50mm thick, including FDA/EC1935 grades, WRAS approved, for drinking water, metal detectable and BS Standards.

Compressed Non-Asbestos Fibre

Compressed Non-Asbestos fibre (CNAF/NAF) is used for high temperature (Up to + 400° C) and/or high pressure (Up to 140 BAR).


Suitable for use with a wide range of medias including oil, fuel, acids, steam and gases.


CNAF is a blend of aramid or inorganic fibres together with a rubber binder, which has been widely used since the ban on asbestos in 1999.


Our range of material is extensive, and we supply material from the worlds leading manufacturers.

Metallic & Semi-Metallic

Designed to withstand extreme pressures (Up to 400 BAR), and high temperatures (Up to + 1000° C), and having excellent chemical resistance, our range of metallic seals is comprehensive.


Our styles of metallic gaskets include Spiral Wound, RTJ’s (Ring Type Joints), Heat Exchanger Gaskets, Machined metal, clad, heat exchanger and tinplate.


If a very low pressure seal is required, our range of sponge may provide the solution. Similar to rubber, the temperature range of sponge, dependent on the grade, ranges from -60° to + 200° C.


We supply two main styles of sponge, Open-Cell and Closed-Cell.


The polymer types include Neoprene, EPDM, Silicone, Viton and PVC Nitrile and can be supplied plain or self-adhesive backed.


Polytetrafluoroethylene has outstanding chemical resistance and a broad temperature range of -200° to + 260° C.


As the material is chemically inert, it is often the preferred choice for gaskets within the food, pharmaceutical, and chemical sectors.


We offer all styles of PTFE including, virgin, expanded, filled and etched so you can be assured of the right product.


Our range of cork materials includes Nitrile and Neoprene bonded corks as well as Nebar®, Tico® and BS grades.


Rubber bonded cork is used in controlled swell environments, particularly for sump gaskets and also for switchgear housings.


Cork provides excellent dampening characteristics making it ideal for a wide range of sealing applications.


We carry a complete range of engineering plastics and offer a full cutting service.


The most common style is our comprehensive range of colour coded plastic shimstock, which means you can easily identify the thickness.


Manufactured from polypropylene or polyester, depending on thickness, we supply full shim sets made from a combination of thicknesses.


Our range of coated papers are used primarily within the automotive industry.


Price sensitive materials are an important requirement within this sector, and our range of oil and fuel resistant grades are ideal for sealing in low heat applications.


Our range of Statite™ and Flexoid™ papers are stocked from 0.15mm to 3mm ensuring you get quick delivery.

High Temperature

Our range of graphite and mica based materials are used for sealing at extremely high temperatures.


Dependent on the grade, this range is suitable for use up to 1000°C.


Commonly used within the automotive, oil and gas, and power industries, our range is produced in accordance with ISO9001:2015 to ensure you get consistent quality.
