The 163 series is a heavy duty polyurethane seal with multiple features that include a double-lipped U-cup design, an internal O-Ring energizer and a reinforced backup ring on the heel. This seal is ideal for applications where high-pressure spikes are like to be encountered. This seal also features additional sealing contact points in the groove.
High-pressure capability and wide temperature range
Excellent fluid compatibility including water-based fluids (H-PU)
Exceptional abrasion resistance
The 163 series rod seal features high-grade polyurethane. Standard materials are MP03 machined H-PU, NBR O-ring and polyacetal backup ring. To suit a variety of applications, the series is also available in NBR, H-NBR, EPDM and high temperature-resistant FPM.
