  • HBY

  • Description

    Description HBY 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 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. * HBY 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. Application None Materials Polyurethane (PU) + Nylon (NY)

MATERIALS

PU

Polyurethane is a material that has the elastic properties of rubber. The proportion in its composition (diisocyanate, polyol, chain extender) is determined by its properties. This material is characterised by a strong mechanical resistance, good wear resistance, high elastic modulus, good flexibility and a very good ozone and oxidation resistance.

Chemical resistance Pure aliphatic hydrocarbons (propane, butane)
Mineral oils and greases
Silicone oils and greases
Water up to +50°C
Compatibility issue Ketones, esters, ethers, alcohols and glycols
Hot water, steam, alkalis, amines and acids
Temperature range -30°C/+90°C
-30°C / +110°C with our PUHT (short term peak at 150°C)
