Characteristics and performance
Design O-Rings are a simple but very versatile seal. They are most commonly used for static applications, and for pressures over 1500 p.s.i are used with back up rings. O-Rings in NBR and FKM are suitable for use in mineral oil, water and air, FKM O-Rings are also suitable for use in most aggressive fluids and in temperatures of up to 200°C/390°F.
Product details
O-Rings with sizes to AS-568A are available in NBR 70 and 90 Shore A compounds and in FKM 75 Shore A.
