Characteristics and performance
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.
Product details
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.
