Parameters necessary to define an O-ring:

ID = Inner diameter

CSD = diameter of the cross section

Kalrez® O-rings are made to AS 568C standard.

=>There is more to consider than the initial purchase price!

Initial purchase price

Installation costs

Unscheduled downtime costs

Monitoring costs

Attendant costs of failure (clean-up, litigations, etc.)

Why use Kalrez® ? Cost of seal ownership !

Using high-performance seals helps to minimize or even eliminate uncontrollable downtime costs.
