Graphited PTFE Packing

Category: PTFE Packing

Product Style Number & Name:

PA4300 Graphited PTFE packing

PA4300L Graphited PTFE packing with lube oil

PA4301 SGPTFE packing

 

Uni-seals GPTFE yarn is a homogenous yarn developed from high quality PTFE resin and graphite powder through special process. It has low friction and good thermal conductivity, and is suitable for most chemical mediums.

 

PA4300 Graphited PTFE packing

The packing is braided from Uni-seals GPTFE yarns. Its consistently high thermal conductivity ensures an effective seal, especially at high temperature and speeds. There are no free graphite particles on the surface therefore little contamination would occur.

 

PA4300L Graphited PTFE packing with lube oil

Braided from Uni-seals GPTFE yarns with silicone lubricant. It is an economical GPTFE packing.

 

PA4301 SGPTFE packing

Braided from super grade Uni-seals GPTFE yarns, it is a good alternative to Gore GFO packing.

 

Applications:

Widely used in pumps, valves, reciprocating and rotating shafts, mixers and agitators. Especially designed for services involving surface speeds and temperature higher than those normally specified for pure PTFE packings.
