Double acting seal for pistons subjected to dynamic loads. It fits into standard O-Ring grooves. The PolyCap™ moves easily, has no stick-slip effect, and is wear-resistant. It uses an O-ring energizer. For longer seal life, it is recommended that a PolyMod® or UltraMod™ low friction O-Ring be used.
PolyCaps™ are available in most PolyFluor™ materials.
Operating Ranges:
- Speed: Reciprocating motion up to approximately 49 ft/s (15 m/s)
- Temperature: Approximately -65°F to +392°F (-54°C to +200°C), depending on the elastomer energizer compound
- Dynamic Pressure: Up to 5,000 PSI (35 Mpa)
