Product details
Blue LDPE stud hole insert designed to protect the bolt holes and raised face of a 3" ANSI 300/600 Class flange.
This flange protector features four ribs that push firmly into the stud bolt holes around the flange perimeter, holding it securely in place during production, transportation, storage and maintenance work. Manufactured from high-density low-pressure polyethylene (LDPE), it shields the gasket sealing surface from moisture ingress, dirt contamination, paint overspray and most mineral oils.

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.
