Aramid Braided Packing For Auto Water Pump Seal

Manufacturers braid Aramid Packing from high-quality DuPont Aramid/Kevlar fiber. It has a PTFE impregnation and a lubricant additive. It is highly durable. It shows good chemical resistance, high elasticity and very low cold flow. It is wear-resistant but may damage the shaft if not used properly. A least shaft hardness of 60 HRC is therefore recommended. Compared with other kinds of packing, it can resist more severe media and higher pressure. The packing is also lubricated with a silicone-based compound for a quick break-in.
