Foot-shaped slip ring combination seal JK2-ⅠB
1. Overview
Foot-shaped slip-ring combination seal JK2-IB is composed of a foot-shaped slip ring filled with polytetrafluoroethylene (PTFE) composite material and an O-shaped rubber ring (GB1235-76). It is used for sealing or static sealing of hydraulic and pneumatic reciprocating unidirectional piston rods (shafts). Generally, open grooves are used.
2. Working conditions
Working pressure: 0～150MPa
Operating temperature: -55～+250℃ (depending on O-ring material)
Reciprocating speed: ≤6m/s
Applicable medium: air, water, water-glycol, mineral oil, acid, alkali, mud, etc.
