12 300# 1/8 THICK FLANGE PROTECTOR

The 0880B1200 is a brown Pressboard Class 300 ring face Flange Gasket with a 12 inch nominal pipe size, a Class 300 pressure rating, and a thickness of 0.125 inch. This flange gasket compresses between two pipe flanges under bolt load to create a leak-tight joint.

This material stands up to dust and debris ingress, handling damage. Pressboard is specified for rigid construction that resists handling damage and consistent thickness for reliable fit. It is not the right choice where wet or chemical exposure or pressure sealing service are present.

It sees regular use in flange face protection, shipping and storage, and construction and turnaround projects.

Stocked as 0880B1200 and sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
