27.1 X 1.6 KALREZ 7075

Kalrez® 7075 Oring

Kalrez®

Shore A Description:

The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer, the harder the compound. Softer compounds stretch easier and seal better on rough surfaces. Harder compounds offer greater abrasion resistance and resistance to extrusion.

60 Shore A is softer than 70

70 Shore A is the standard

90 Short A is very stiff

Specs:

Broadens sealing options with a perfluoroelastomer that has enhanced physical performance properties including very low compression set, and improved seal force retention. It is a carbon black filled compound with mechanical properties designed for improving sealing performance in both high temperature environments and temperature cycling situations. To provide even greater sealing performance in dynamic applications where low friction is required, 7075 O-rings have a glossier finish than others.

Material:

7075 (Kalrez®)

Maximum Continuous Service Temperature: 327°C/620°F

Application:

7075 was specifically developed to be used as an O-ring or custom-sealing component in the chemical and hydrocarbon industries with an improved thermal resistance. Provides more chemical resistance than compound 4079.
