Description
Tefapak GRF 260 Gland Packing
The GRF 260 gland packing is based on gPTFE, i.e., graphitized, expanded PTFE. The GRF packing is made of PTFE foil thin strips braided with graphite addition. The high graphite content improves thermal conductivity, sliding properties and reduces friction wear, which significantly extends the service life in dynamic applications.
