Product details
Plastic stud hole insert that plugs the bolt holes of a 2.5" flange to protect the sealing surface during storage, transit and maintenance.
These inserts feature four ribs that anchor into the stud holes of the flange, holding the protector firmly in place over the flange face. Manufactured from durable LDPE, they resist moisture, dirt, paint splatter and most oils, making them ideal for protecting costly flange equipment in refining, hydraulics and oil and gas operations.

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.
