Moulded Parts
-25 and -25L
Moulded Part Material
Fluid resistant modified Elastomer

1 Designed to be used in conjunction with
components such as DR-25 tubing and S1125
adhesive. Being specifically formulated and
2 designed to provide optimum high-temperature
fluid resistance and long term heat resistance.
This unique balance of properties makes -25
