Sigma 225 CombinationPacking PTFE + Polyamide Fibre Gland Packing
ITEM : Sigma 225

PRODUCT NAME : Sigma 225 CombinationPacking PTFE + Polyamide Fibre Gland Packing



APPLICATIONS / USES : A Special application performance packing made of  combination of Pure PTFE fibre with additional polyamide synthetic fibre reinforced in core & all four corners to provide sliding surface and heat dissipation property. The combining benefit of pure PTFE, Polyamide & high temp resistance lubricants gland packing offers longer sealing ability due to excellent dimensional ability.
