The Hallite 660 is a buffer seal developed to work in conjunction with high performance rod seals. It is interchangeable with common PTFE buffer seal housings.
The seal which is manufactured in Hythane® 181, is designed to provide a valve action to prevent excessive pressure build up in the cavity between the buffer seal and the rod seal. A polyacetal anti-extrusion ring is fitted to provide maximum extrusion resistance against shock pressure loads.
- T660 allow oils to reach the primary seal at low pressure preventing the primary seal from running dry.
- It will self energize for maximum seal ability at high pressure or during shock load to protect the primary seal from it.
- If there is ever a pressure trap, it will release the trapped pressure at the lowest level when compared to other buffers in the market.
- Easy installation.
- Long life.
