18

A medium to heavy duty single acting seal, the Hallite 18 has shown itself over the years to be an effective and robust seal in a wide variety of applications.

The seal comprises a rubberised fabric U form base to which is bonded a rubber energiser.

The seal section is pre-loaded by the housing when installed to ensure effective sealing at low pressure. When the pressure increases the rubber energises the U form to increase the sealing area and hence the efficiency of the seal. The strength and durability of the rubberised fabric combines with its ability to retain lubricant keeping friction and wear to a minimum.

In a piston application the Hallite 18 should not be used back to back to make a double acting assembly.

NB:  Size lists give “on line” tolerances for rod applications.
