About PTFE +Spring Piston Rod Seal
DESCRIPTION :
-One-sided with pressure applied to seal
-Metal spring is used as pre-load component for the sealing lips
-System pressure overrides the pre-load during operation.
ADVANTAGES:
-Small housing -Suitable for high pressures and vacuum
-Universal chemical resistance -Large temperature range
-Good dry running properties -Low friction forces
-Free of stick-slip -Resistant to ageing
-Permanently elastic due to metal spring.
-Suitable for stroke, rotary, pivoting movements and for static applications
APPLICATION:
Fittings manufacture, general chemistry, mechanical engineering,foodstuffs industry, pharmaceuticals, petrochemicals. e.g. ball cocks, flanges/covers, rotary joints and manifolds, hot water and steam valves, valve journals, control shafts, reciprocating pumps, bearings.
