Mowtec use a variety of rubber compounds to manufacture its O-Rings, Gaskets and Sealing Solutions.

Silcione compounds are generally superior as static seals in extreme temperature environments, handling operating temperatures from -65°C to 205°C. Some properties such as tear strength and thermal conductivity can, at extreme temperatures, be far superior to organic rubbers. Fluorosilicone or FVMQ is a silicone polymer chain with fluorinated side-chains for improved oil and fuel resistance, and is hence used extensively through the aerospace industry. It combines these properties with the high and low temperature stability of general silicones. Due to relatively low tear strength, high friction and limited abrasion resistance this material is, however, not generally used for dynamic applications, and is not recommended for exposure to brake fluids or ketones.
Neoprene (-40°C – 250°C) features good resistance to petroleum oils, ozone, and sunlight and oxygen degradation. More resilient that many natural or synthetic rubbers, this relative strength renders it ideally suited to many demanding applications and environments.
Nitrile, also known as Buna-N or NBR, is a widely used elastomer due to its excellent resistance to petroleum products and expansive operating temperature range (-40°C – 108°C). Often used as the rubber of choice in the automotive and aerospace industries’ fuel handling systems. Nitrile is more resistant to oils and acids than naturals rubbers, though can be degraded through contact with ozones, ketones, esters and aldehydes.
Viton is a fluorocarbon elastomer commonly used in O-Rings and other moulded goods. Viton is well resistant to chemicals, oils and extremes in temperature, and maintains these characteristics well as it ages. Applications include aircraft engines, automotive fuel systems, SCUBA gear and chemical processing industries and high vacuum environments. Viton is generally compatible with hydrocarbons, but is not recommended to exposure to ketones, alkalis, organic acids or with the aviation hydraulic Skydrol fluids.  
With high tensile strength and tremendous abrasion resistance, the physical properties of Polyurethane are among the best of all O-Ring elastomers. Often used for sealing high hydraulic pressure applications, or where parts are subject to a high amount of wear, Polyurethane exhibits excellent resistance to oil and petroleum products, as well as many solvents and alcohols. However, it is not recommended for exposure to concentrated acids, ketones, brake fluids, or very strong oxidizing agents.
Ethylene-Propylene or EPDM exhibits tremendous resistance to heat, water, steam, ozone, sunlight and other weather. It also has excellent electrical insulating properties and good resistance to ketones, diluted acids and alkalines. EPDM however exhibits unsatisfactory compatibility with most oils, gasoline, kerosene, halogenated solvents and concentrated acids. EPDM is often used in seals and O-Rings which will be exposed to weather and temperature extremes.
Polytetrafluoroehylene or PTFE is often used around in electrical components in the aerospace industry, thanks to its excellent dielectric properties. Low friction combined with its high operating temperature makes PTFE a high-performance substitute for weaker lower-melting point polyethylene, and a material of choice in dynamic applications.

Quality Management

ISO 9001:2008 accredited for the manufacture of elastomeric components


All our products are 100 per cent hand finished by our expert Finishing Team. Any flash or loose material is removed and the end product thoroughly cleaned before being individually packaged in aerospace grade UV-protection envelopes, ready for delivery to you.


Our rings are inspected under various levels of magnification to ensure that all end products are free from defects, foreign matter and other contaminants. A batch sample is also dimension checked to the original drawing specification to ensure tolerances are met and with shadowgraphs, digital protractors and IRHD hardness devices in-house you can rest assured that all our products are ready and fit for purpose.

Quality Management

Mowtec are fully BSI ISO 9001:2008 accredited, and as such maintain a high level of traceability and process standardization across our production and inspection procedures. The scope of our registration covers the manufacture of elastomeric components and assemblies for medical and industries applications. Our ISO 9001:2008 accreditation underpins our commitment to offering high quality sealing solutions throughout every level of the company. Our Quality Team are constantly working both internally and externally with our customers to help improve and advise, all of which helps to create an excellent supplier-customer relationship that we would love for you to be a part of.
