ARTIC BLF - Zero Exstrusion,

in one seal

Gapi launches the revolutionary “Artic BLF” new sealing solution that has been specifically designed to meet the ever increasing demands placed upon Hydraulic Rod Seals, where designers require reduced sliding friction and increased extrusion resistance whilst operating at high pressures.

The sealing problem

The main sealing problem caused by friction is heat. Heat is generated by contact between the seal and the rod. Increasing the contact area is proportional to the increase in pressure, thus resulting in higher operating temperatures at higher pressures. Therefore, the solution to increased temperatures is the effective dissipation of heat generated by the seal. The consequence of higher temperatures is a natural softening of the seal material, resulting in a higher risk of the seal being extruded. The most common solution to this problem is the introduction of an anti-extrusion ring mounted around the seal base.
