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 |

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 |
