Burajet SCW 8032/SCW is a fiber injectable packing based on PTFE fiber with a heavy-duty lubricant. For some applications, it may be necessary to retain it between braided compression packings (e.g. Burasoft L 6225/L or Buramex 6335). To reduce product contamination and to compensate better for radial shaft movements, a special retention between HPU (hydrolysis-resistant polyurethane) or FKM (fluorocarbon rubber) lipped rings is used.
