H68C is a stationary-based seal with

the spring located in the stationary.

An additional rubber cup is fitted over

the H68 base, allowing for an easier

push-fit. This eliminates the need for

any special tools.

 

Available in two standards. Metric dimensions based on Japanese Automotive industry standard "EH790-TF" design. Imperial dimensions based

on industry standard "Type 6A Cup".
