Expanded Graphite Packing – Type: CH GR1

Grafan material is essentially pure carbon in Graphite form processed into a flexible foil material without fillers, binders nor other additives. The product is self lubricating, dimensionally stable, impervious to gases and fluids, and shows exceptional temperature and chemical resistance. Grafan offers unrivalled sealing capabilities under extreme temperature, media and pressure conditions giving extended packing life.                                                        
Graphite in this form is self-lubricating with a low coefficient of friction (comparable to Teflon), high thermal conductivity and permanent volumetric elasticity (spring back) which results in no volume reduction (compression set) in use. Resilient with ideal fluid and gas sealing characteristics and extreme capabilities, Grafan offers the ultimate range and performance in packing material.

Carsten Holms CH GR1 is a crimped Grafan Ribbon Tape, available from 6mm to 75mm wide, for in-situ packing of Valve Stems and then it is easily compressed into a uniform packing ring. Using this system, a small tape inventory can pack any size of gland with superior service results.
