Product details
Stud hole insert with four ribs that engage the bolt holes of a large flange to protect the sealing face from damage, dirt and moisture.
This flange protector fits over the raised face of a DN 250 300 Class flange, with four integral ribs that locate into the stud holes to hold the cap securely in place. Moulded from rigid LDPE, it shields the gasket face and bolt threads during production, transport and storage, and resists moisture, dirt, paint and most mineral oils. Quick and cost-effective to fit, it is widely used in oil and gas refining, hydraulic plant and pipe fabrication.

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.
