SUB

Description

The single piston or throat profile of the SUB is very suitable for working at low pressures due to the presence of the O-ring. At low pressures, the ring increases the force to seal and prevent by-pass. This type of seals is used back to back for dual function. Easy installation due to flexibility, excellent wear resistance, and good stability due to its depth. Its profile is made of polyurethane and the reinforcing ring is made of NBR.
