Product Description

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.
