Product details
Four-rib stud hole insert that pushes into bolt holes to protect flange faces from damage, dirt, moisture and contamination.
Designed for 1" nominal diameter flanges rated 300/600 class, these inserts offer a quick-fit alternative to full-face flange caps. The four ribs engage the stud holes around the flange perimeter, holding the insert securely in place during production, transport, storage and maintenance work. LDPE construction provides chemical resistance to oils, water and most industrial solvents.

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.
