Parker’s Extreme High Temperature Seal Option will provide OEM’s and End Users an increase in machine productivity through improved resistance to heat degradation as compared to typical fluorocarbon seals. With a maximum continuous temperature rating of 400° F, the Extreme High Temperature Seal Option will allow longer service life in applications that require the use of alternative fluid types and demand superior heat resistance. Parker’s innovative seal design utilizes PTFE materials that are constantly energized to provide excellent seal performance and long life. Customers utilizing this design will realize a reduction in machine downtime due to seal failure associated with high temperature exposure.

Wiperseal

Unique profile of bronze filled PTFE wiperseal provides performance of a third rod seal while scraping contaminants from the piston rod as it retracts.  A fluorocarbon energizer ensures constant contact of wiperseal to the piston rod. 

Piston Rod Seals

Dual bronze filled PTFE rod seals with fluorocarbon energizing rings provide leak-free performance, long life, and heat resistance to 400° F. 

Piston Seals

Carbon graphite filled PTFE piston lipseals have an internal stainless steel spring that energizes both the dynamic and static seal lips to provide optimal sealing throughout the operating temperature range. 

Piston Bearing

Non-metallic piston wear band has temperature resistance to 400° F. 

End Seals

Pressure-actuated fluorocarbon cylinder body-to-head and cap O-rings. 

Piston Rod Thread

Piston is secured to rod with set screw.
