3700 ACRYLIC FIBER WITH PHENOLIC FIBER IN CORNERS BRAIDED PACKING
Made of polypropylene fiber by reinforcing, braiding and impregnating with PTFE. Phenolic fiber in corners give the packing much better wear resistance.

The base material and process are the same as MK8000, supplemented by a silicone rubber material as an elastomer at the center. The product has better compression compensation performance. It is suitable for pumps, valves and kettles with higher linear speed and higher pressure.
