description Hallite 18 Overview
Hallite 18 is a fluid-power piston seal profile made by Hallite, a manufacturer of sealing products for hydraulic and pneumatic equipment. Hallite's catalog identifies the 18 as a legacy single-acting piston seal, a profile associated with older fluid-power cylinder designs. It is intended for piston sealing in cylinders, so it is relevant to engineers and maintenance teams selecting replacement seals for established cylinder applications.
help Hallite 18 FAQ
Is Hallite 18 a double-acting piston seal?
Hallite's product information identifies Hallite 18 as a single-acting piston seal, not a double-acting seal. The manufacturer specifically warns against installing two Hallite 18 seals back-to-back to create a double-acting assembly.
What is Hallite 18 made from?
The seal uses a rubberized fabric U-shaped base with a bonded rubber energizer. Its preloaded design helps maintain sealing at low pressure in a piston application.
Where is Hallite 18 used?
Hallite 18 is intended for single-acting reciprocating piston applications in fluid-power equipment. It should be selected only after checking the cylinder design, pressure, temperature, fluid, and groove dimensions.
Can Hallite 18 be used in a double-acting cylinder?
Not as a single back-to-back pair assembled from Hallite 18 sections, because Hallite warns against that configuration. A purpose-designed double-acting piston seal should be selected for pressure on both sides of the piston.
