Pressboard Flange Protectors

Pressboard Flange Protectors are an economical, full-face solution designed to protect flange sealing surfaces during shipping, storage, and handling. Manufactured from durable tempered Masonite hardboard, these protectors help prevent nicks, corrosion, and surface damage that can lead to costly rework, delays, or rejected parts.

For manufacturers, fabricators, and distributors, pressboard flange protection is a simple, cost-effective way to preserve product quality and protect profit.


Economical Full-Face Flange Protection

Pressboard flange protectors are designed to completely cover the face of the flange, shielding critical sealing surfaces from impact, debris, and environmental exposure. As a result, they are widely used for domestic shipments, yard storage, and general material handling where dependable protection is required at a low cost.

Because they are lightweight and easy to install, these flange face protectors provide reliable coverage without slowing down operations or adding unnecessary expense.


Durable Masonite Construction

Each protector is manufactured from 1/8″ thick tempered Masonite hardboard, offering a strong balance of rigidity and impact resistance. This material helps maintain consistent protection during handling while remaining economical for high-volume use.

Unlike flimsy alternatives, Masonite pressboard holds its shape and continues to protect the flange face throughout shipping and storage.
