Description

For use in control valves, Rod and piston air, oil and water services.

Features

Lower friction : Friction a measurement of the resistance to sliding between a seal and hardware surfaces, is directly related to seal material coefficient of frictionand the total load.

Longer Life : Individual sealing rings expand under bolt loading to maintain a tight, virtually leak proof set with up to 50% longer services over braided styles.

PTEE : Teflon(Dupont’s Registered Trademark)

Main Use

O-Ring for Static Seal is used for vacuum units, Cryostats, Compressed container for LPG, High temp engine components, High pressure extruders,Equipment for nuclear power plant and other equipments for space development and marine development.

The O-Ring will cause restoring forcewhen the pressure is increased making balance between the ring insideand fluid pressure as shown in the left picture for high pressure because it has a small groove in several placesof the ring inside and outside.Good for high pressure rather than basic type. Normally it is used at 70kgf/㎠or above.
