Product details
Four-rib LDPE stud hole insert designed to protect 3/4" flange faces from contamination and damage.
This stud hole insert pushes into the bolt holes around a flange perimeter to fully cover and seal the gasket face. Manufactured from high-density low-pressure polyethylene, it resists moisture, dirt, paint and most oils, making it ideal for protection during production, transportation, storage and maintenance work.
Common in oil and gas refining and hydraulic applications where protecting costly flange equipment cost-effectively is essential.

Sizing questions
Which class do I need?
Use the pressure class stamped on the flange rim. Inserts are sized to the bolt holes of that class, so an insert for a different class may not fit.
How many do I need?
One insert per bolt hole. The bolt-hole count depends on the flange size and class — count the holes on your flange.
ANSI or DIN — which is my flange?
ANSI / ASME flanges are sized in inches (for example 4") with a pressure class such as 150 or 300. DIN / EN flanges are sized in DN (for example DN 100) with a PN rating. The standard and size are normally stamped on the flange rim.
