Designed for 7,000 psi (480 bar) working pressure and pressure spikes to 20,000 psi (1380 bar). Our seal was developed for excavator attachment cylinders when no existing seal would meet our 1 year, 2000 hour minimum performance requirement. This patented (5,934,658) design has more than double the life compared to any other seal tested.
* Our piston ring is machined from moisture stabilized bearing grade nylon.
* Steps of the piston ring are wider than ring and fit tight in the groove, for excellent low pressure sealing.
* Expander and piston ring fill the groove volume by over 90% to eliminate explosive decompression of the expander ring when dropping from maximum pressure quickly.
