BPG 7888


This engineered low fugitive emission valve packing set is featuring a combination of braided wire reinforced expanded graphite rings and a highly adaptable core. The permanently elastic components of the sealing set ensure lowest leakage rates and reduced friction over the entire life cycle of the valve.



Our BPG 7888 sealing set is designed for use in low fugitive emission valve applications.
