Bolt Hole Flange Protectors
In stock
Flange Protection Discs are easy to fit. The disc has four pre-punched holes, through which cable ties can be easily attached for a secure fit. When needed other fastening products such as retainer plugs, pins and washers can also be applied.
These protective discs provide cost-effective full face protection for a flanges exposed sealing surface. They have a special design with multiple holes to match the flanges bolt hole diameter and bolt circle.
The extensive range covers a variety of sizes and pressure ratings. They includes options that are suitable for ANSI B16.5 and ASME B16.47 flange dimensions - Pressure Groups 150, 300, 600, 9 00, 1500 and 2500 pounds (lb).
Ensure you select an appropriate protector by first measuring both the Outside Diameter and Bolt Circle Diameter of your flange.
