8515 (TA-Luft VDI 2440 & API 622 2nd certified)

It is a gland packing made by braiding yarn (PAT) containing PTFE film in the outer covering of MacFoil (expanded graphite) in a cross-sectional angular shape.
Since the surface of the gland packing is covered with the PTFE film, the thermal expansion during thermal cycling and the relaxation of thermal shrinkage stress (surface pressure lowering) in the PTFE-based gland packing have been greatly suppressed, I will.
This is a new type of gland packing that can achieve stable performance over a long period of time.
