Piston and Rod T-seals

Materials: Nitrile rubber seal with split hard plastic Backup rings on either side of the sealing element

Applications: The assembly installs in a standard O-ring groove. T-seals resist spiralling and extrusion and are available in Intermediate and Wide Base styles to suit MIL-5514F O-ring glands designed for 1 or 2 Backup rings respectively

Piston Seal 5 piece
Double Acting Solid (DAS) Style

Materials: Nitrile rubber sealing element supported by 2 polyester Backup rings and 2 polyacetal wear rings

Applications: Medium to heavy duty seals that can be used in a wide variety of conditions and either solid or split pistons

Glide Ring Piston Seals

Materials: PS1400 and PS1600 - glass filled PTFE with round rubber O-ring energiser PS1500 - same size as PS1400 but molded from 60 Durometer polyurethane with a band of molybdenum molded into the OD to reduce friction PS1800 - glass filled PTFE with square section rubber O-ring energiser

Applications: Glide Ring Piston Seals provide a low friction seal that can be installed in a space saving housing. They use standard O-ring energisers that allow a wide range of fluid and operating temperature compatibilities
