Product details
LDPE stud hole insert that plugs the four bolt holes of a 1/2" 150 Class flange to protect the raised face from contamination and handling damage.
Flange stud hole inserts are designed to cover and seal the critical gasket face of a flange without fitting into the bore. Four ribs engage the stud bolt holes around the flange perimeter, holding the insert firmly in place during production, transport, storage and maintenance work. The material resists moisture, dirt, paint spray and most oils, making it ideal for protecting expensive flange assemblies in harsh environments.

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.
