Sealing Solution for Hydraulic, Pneumatic and Oleo-Pneumatic Applications

JF4 sealing rings are seals with a cross-section comprising 4 lobes. JF4 sealing rings offer a better solution to ensure tightness of hydraulic, pneumatic and oleo-pneumatic devices.

They are particularly suitable for dynamic applications such as:

alternating movements
rotating movements


No direction of assembly
Reduced size: lighter weight and cost reduction
Friction reduction
Reduced starting torque
Dual sealing line
Limited residual film
Less wear
No twisting
Increased durability of the product
