Fluorocarbon 70 Durometer O-Ring, High Temperature, Black (V

产品概况：

 

Parker's VA179 (Fluorocarbon 70 Durometer) has excellent compression set resistance at temperatures exceeding the capability of traditional fluorocarbon (FKM) options. This makes VA179 the longest lasting fluorocarbon seal in the industry capable up to even 225°C (437°F). VA179 can be used across a range of markets including General Industrial, Automotive, Aerospace and Semiconductor.
