3/4" Class 150 Flange Stud Hole Insert - Blue LDPE

Blue LDPE stud hole insert that plugs the four bolt holes of a 3/4" 150 Class flange to protect the gasket face from contamination and damage.

These inserts are designed for flanges with protruding bolt holes around the raised face. Four ribs push firmly into the stud holes to hold the cap in place, offering a quick and cost-effective alternative to full-face protectors. Commonly used in oil and gas refining, hydraulic systems and industrial production where flange protection during fabrication, transport and storage minimises costly damage to equipment.
