Enviropak 1121 is a thermally stable, chemically resistant, dry white PTFE fiber packing that will not harden or shrink in size in any valve service meeting Valve Manufacturer's Association specifications*.
Thermograf is a resilient, compressible, self-lubricating, chemically inert, thermally conductive, braided flexible graphite packing. Once compressed, Thermograf 1200 becomes a totally homogenous ring that remains responsive to gland and system pressure changes. Thermograf offers optimum sealability from a braided packing for valves or pumps.

Enviropak 3450 is produced from a high quality carbon core over which a double Inconel® wire inserted carbon yarn jacket is braided. The result is a stiff construction able to withstand high pressure. It will provide excellent performance in super heated steam. Enviropak 3450 is the perfect packing for air or motor activated valves when constant cycling demands the best.
