O-Rings by Cross Section

O-Rings by Cross Section | Mayday Seals & Bearings

We carry an extensive range of O-Rings in the most common materials:

 • Nitrile (Buna / NBR)

• Fluoroelastomer (FPM / FKM / Fluorocarbon / Viton®)

• Silicone


Additionally we can usually supply many other non-standard polymers such as High Nitrile, PTFE, Polyurethane (PU), PTFE Encapsulated Silicone and Viton® (FEP), HNBR, Aflas®, most in a range of colours and Shore Hardnesses.

For those more demanding situations, we can also offer a range of Perfluroelastomers / FFKMs – including Kalrez®, Chemraz®, Isolast® and Perlast® amongst others.

We are able to offer moulded non-standard O-rings up to 700mm ID with a full range of cross sections in many materials, hardnesses.

For static applications with non-standard sizes we can also offer Scarf Jointed and Vulcanised rings as cost effective alternatives to moulded rings.
