Silicone rubber gaskets — a detailed description

We use the latest equipment to manufacture the most accurate silicone gaskets, for the best price. For example, silicone washers can be stamped from a strip using a punching machine. Or parted from silicone tubing using modern precision cutting machines — to maintain tight tolerances.

It all depends on the type of gasket rubber you need. (Not sure? Then get in touch — we can help.)

We use the following methods to ensure consistency and precision:

Die Cutting
Waterjet Cutting
CNC Cutting
Laser Cutting
Quality Control
Our BS EN ISO 9001:2015 quality control system guarantees our silicone gaskets are made to a high-standard; to the required tolerances. And that they are thoroughly checked. We have technical advisors to make sure that all of our silicone rubber gaskets are tailor made to suit their specific application.

Silicone rubber gaskets — properties & technical information
Silicone gaskets are often chosen for their stability over a wide temperature range. They have excellent resistance to chemicals, fire, fungal growth, aging and ozone. Mechanically, silicone has outstanding tensile strength, elongation, tear strength and compression set. Silicone is versatile with a long service, making it suitable for a diverse range of applications. Specific properties of our general purpose silicone include:

Long service life over a wide range of temperatures (-70⁰C to +200⁰C)
FDA Approval 21CFR 177.2600
Odourless and Tasteless
Ozone and UV Resistance
WRC approval M103580/A-H
Certified to USP Class VI.
We also offer two flame retardant grades developed for mass transit and aerospace grades which meet the following specific requirements:

VFR(2) (mass transit)
VFR603 (aerospace)
BS EN ISO 4589-3 1996 (Category 1A conformity)
FAR/JAR 25.853
FAR/JAR 25.855
NF F 16-101 & NF F 16-102 Classification: F0
Other grades available include: platinum cured, metal detectable, high temperature, high tear strength, silicone sponge. We are happy to advise on the best grade for your specific application.

We are able to offer these grades in a range of colours (including a colour matching service) and a range of shore hardnesses.
