Rubber Seals Enquiry
Grades of rubber materials can vary significantly in terms of quality, therefore we only supply rubber manufactured to high standards, from reputable and reliable suppliers which means you get consistent quality.
Below are the many different types of gasket material that we manufacture and supply, what they are suitable for, as chemical resistance and operating temperature vary depending on the type of rubber.
Types of Rubber Gasket Materials

EPDM Rubber Gaskets
Butyl gaskets are used with corrosive chemicals like alkaline’s and mineral and aqueous acids. It has good heat resistance (up to 130° C) and excellent ageing properties.
EPDM rubber gaskets are used in a wide variety of situations. They exhibit good resistance to alkali’s and acids. Commonly used for sealing against water, EPDM’s are also suitable for use with phosphate ethers and solvents.
This high-grade EPDM is WRAS (Water Research Advisory Service) approved, meaning it is suitable for gaskets that are used in potable drinking water applications, like pipelines and washers.
This grade is suitable for use in food and beverage applications because it is compliant with FDA and EC1935:2004. It is resistant to many chemicals and ozone. It can be used at a high temperature – up to 115° C.
Hypalon & Natural Rubber Gaskets
Hypalon is resistant to most inorganic chemical products. It has good resistance to general acids, oils, and greases. Also, it has excellent resistance to oxidation and ozone. CSM’s also resist fire and are self-extinguishing when the flame is removed.
Tan para, or shotblast is extremely abrasion resistant so if you need a gasket to be resilient, this may be the best choice, with it being a natural rubber, it can operate down to -40° C. It is very soft so will compress well.
SBR/Commercial gaskets are suitable for a variety of low-pressure gaskets. It has good resistance to many inorganic chemical products but limited oil resistance. SBR is not suitable for use with oxidising acids or general organic liquids.
WFQ Natural rubber is suitable for a variety of sealing applications and food stuffs. All the ingredients in this formulation have been checked against the latest update of the CFR21 FDA 177-2600 ingredient listings and are present at the level permitted.
This high-grade range meets the BS Standard 1154. There are 5 grades described by their hardness Z40, Z50, Z60, Z70 and Z80. By using a BS grade such as this means you get consistency of supply as, no matter the manufacturer, the grade must comply.
The fibreglass or cloth insertion in this option means that the gaskets have additional strength and wont’s stretch as much as non-reinforced grades. Its chemical resistance properties are the same as SBR without the reinforcement.
Neoprene Rubber Gaskets
Neoprene rubber was one of the first synthetic polymers to be developed. It is resistant to inorganic chemical products except oxidising acids and halogens. It has good resistance to heat, ozone, and weathering. We also offer this grade with an insertion.
Our flame retardant Neoprene provides additional safety in the workplace. We offer 2 grades, NCB158 (National Coal Board Spec.) which is also anti-static, and grades that comply with BS476.
Our BS2752 range complies with the exacting British Standard to ensure your gaskets always meet the same specification. The range covers 5 hardness’s from 40 Sh to 80 Sh.
Gaskets made in white food quality Neoprene have the same chemical resistance as black Neoprene but are made with ingredients that comply with both FDA and EC1935:2004 regulations, making them suitable for food use.
Acrylonitrile Butadiene/Nitrile Rubber Gaskets
Nitrile rubber gaskets are resistant to various oils and can be used at relatively high temperatures. It should be noted though, that with the increase of Biofuel in petrol and diesel, care should be taken in these applications. A reinforced grade is also available.
This high grade Semperit gasket material has good mechanical properties and is suitable for use with unleaded fuel with a swell rate of around 20% compared to a commercial Nitrile’s 60%. It is suitable for most aliphatic and aromatic oils.
With a choice of 5 hardness’s BS2751 Nitrile gaskets are made to the same exacting standards, no matter the rubber manufacturer. Gaskets made in these grades will last longer in service than commercial NBR grades.
Suitable for contact with dry foods with outstanding oil resistance. This grade is mostly used within the food processing industry. Compliant with both EC1935:2004 regulations and CFR21 FDA 177-2600.
Blue gaskets are becoming increasingly popular within the food industry because there are very few blue foods, making it easier to spot a gasket leak. This grade complies with EC1935:2004 and FDA regulations.
The food safe additives in this high-grade Nitrile mean that if the gasket fails, metal detectors, commonly installed on food processing and pharmaceutical lines can pick up on it. Again, it complies with FDA and EC1935:2004.
Silicone Rubber Gaskets
We manufacture Silicone gaskets in a range of colours. All our Silicone is WRAS approved and FDA/EC1935 compliant. Silicone is widely renown for it’s outstanding resistance to a wide range of general chemical products and can operate at high temperatures, +230° C Continuous, +250° C Intermittent.
Platinum cured silicone has better tensile and tear strength than peroxide cured silicone. It can also be made clearer because of the curing process which makes it the preferred material in medical, pharmaceutical and food sectors.
This softer grade of silicone is ideal for making gaskets that can be used in low pressure sealing applications. Because all silicones are inert, it makes them the preferred choice for many food and beverage processing plants.
Our blue FDA metal detectable silicone gaskets are used in food processing industries and the pharmaceutical sector. The grade has food safe particles within it that can be picked up by a metal detector in the event of failure.
Viton and FKM Rubber Gaskets
Fluoroelastomers have some of the best chemical resistance amongst synthetic polymers. These FDA compliant grades are ideal for use in many environments, for instance, pharmaceutical, where there is exposure to harsh chemicals or solvents.
This speciality polymer is part of the Viton family of materials. Viton gaskets are usually used in situations where resistance to heat, fuels or chlorinated solvents is required. Viton has excellent resistance to hydrocarbons, aliphatics, aromatics, and chlorinated chemicals.
FKM fluoroelastomer is priced competitively for applications that are cost sensitive. Having excellent resistance and resistant to ozone, oxygen and natural weathering means that gaskets made from FKM have a long service life.
This Nomex reinforced FKM is used where additional strength is required in applications like diaphragms. It has a minimum fluorine content of 66% which means it is extremely chemical resistant and durable.
As with all types of rubber gasket, it is recommended that the polymer type is tested for suitability as grades do vary.
We are happy to advise on any application, but final responsibility lies with the customer.

Frequently Asked Questions
How do rubber gaskets work?
When gasket material is squeezed between two surfaces and then displaced, a seal is produced that can withstand movement, vibration, temperature changes, and the presence of chemicals, fluids, oils, and steam.
What are rubber gaskets used for?
EPDM gaskets may be used in a wide range of applications. They have a strong alkali and acid resistance. EPDMs are commonly used to protect against water, but they may also be utilised with phosphate ethers and solvents.
What is the difference between a rubber gasket and an O-Ring?
Gaskets are flat pieces of material that are used to secure two flat surfaces together, generally with a bolted junction.
O-rings are ring-shaped, spherical components that must fit into a groove to provide protection between two sections.
What are the different types of rubber gasket materials?
Rubber Gaskets can be made in a wide variety of shapes and styles dependent on the industries that are used in. The most common gaskets are round and can be supplied with or without holes. You can view our comprehensive range of rubber gasket materials we can manufacture above.
