Flexible Graphite Compression Packing Seal, Shiny Gray, 7/16 in Square, 25 ft Length
Flexible Graphite Compression Packing Seal, Shiny Gray, 7/16 in Square, 25 ft Length
This shiny gray flexible graphite packing is a braided rope for sealing pumps and valves in both stationary and moving setups. Its expanded graphite yarn carries heat away from the shaft, which supports high shaft speeds and lowers friction across cold and hot operating ranges. The packing grows denser each time the gland follower is tightened, and it contains an anti-corrosion additive.
Pressure ceilings are 2,500 psi for valve service and 125 psi for pump service. It handles media across a pH range of 0-14, excluding fuming nitric acid, aqua regia, and oleum. Operating temperatures run from -400 F to 6,000 F in non-oxidizing atmospheres, with upper limits of 850 F in oxidizing atmospheres and 1,200 F in steam. Suitable for low-pressure steam valves, boiler feed pumps, and expansion joints.
