PDWA Elastomers

["John & Allison Cyganowski" <janah@att.net>]

Hi All,

I have just about finished re-conditioning a spare Pressure Differential 
Warning Actuator (PDWA).  I would like to replace the o-rings on the 
shuttle.  What material of construction should these be?  EPR? Viton? I 
would like to be able to use DOT4 or DOT5 with this component and live to 
tell about it ;-)
