PPH Backing Rings

PPH Backing Rings are precision-molded components used to reinforce and support flange connections in plastic piping systems. Made from Polypropylene Homopolymer (PPH), these rings are designed to be used in conjunction with stub ends or flanged joints, ensuring proper compression of the gasket and providing a leak-proof, strong mechanical joint.

Due to their high chemical resistance, lightweight, and non-corrosive properties, PPH backing rings are widely used in chemical processing, industrial fluid transport, wastewater management, and corrosive fluid pipelines.

Key Features of PPH Backing Rings

Strong Mechanical Support – Ensures proper flange alignment and even gasket compression.
Excellent Chemical Resistance – Ideal for corrosive environments including acid, alkali, and saltwater exposure.
Corrosion-Free Material – Will not rust or corrode, even under harsh conditions.
Lightweight and Durable – Easier to handle and install than metal alternatives.
UV & Weather Resistant – Suitable for outdoor applications.
Compatible with PPH Flanged Systems – Designed for perfect fit with PPH stub ends.
Reusable – Can be dismantled and reused for maintenance or system modification.
