Carsten Holms CH AR3 combines the benefits of the remarkable properties of two outstanding gland packing fibres, G1 has the best combination of features of any packingfibre but it may extrude or deteriorate in high mechanical loading conditions. The addition of Du Pont’s Kevlar® adds steel like strength. CH AR3 G1 Kevlar® combi-packing is square inter-braided to add the strength of Kevlar® where it is most needed on the corner posts for dimensional stability and to resist extrusion. The G1 yarns are braided to the packing surfaces to enhance smooth running and sealing capability.
CH AR3 is THE packing for extended life in high pressure or mechanical load conditions, particularly on worn or large tolerance equipment and in the most demanding chemical environments. Shaft wear is virtually eliminated, and high speeds and aggressive chemicals can be handled, because of the presence of G1 on sealing faces. Extrusion and gland maintenance is negligible, even in the most arduous of applications, due to the inter-locked braiding of Kevlar®.
