Parker Hannifin Stat-O-seal
Nitrile O-ring molded in place within a metal washer

Parker Hannifin Stat-O-Seal is a two-piece combination seal comprising a separately molded nitrile O-ring fitted within a surrounding aluminum washer. The cross section free height of the O-ring is greater than the metal retainer, providing the proper compression without squeezing the seal beyond its elastic limit.

Features:
•	No machined O-ring grooves are required in the mating flange
•	Precisely controlled optimum percent squeeze eliminates over compression
•	The retainer edge is visible after installation allowing for easy visual inspection
•	The self centering design provides easy and accurate placement of the seal
•	The solid metal to metal contact improves joint stability and eliminates re-torquing
•	Long reliable service and a high level of reusability
•	Rubber/bolt interference provides for easy assembly
