PQ
The PQ Piston Seal provides excellent sealing for applications requiring low friction and zero drift performance. The PQ Seal is a double-acting, three-piece design featuring a PTFE Seal Ring with a Nitrile (NBR) Square Ring energizer and Nitrile (NBR) X-Ring sealing element that is nested into the channel of the PTFE Seal Ring.
The X-Ring provides zero leak performance while the PTFE Seal provides high pressure and contamination protection.
