Galv Backing Ring PN16

Built for the demanding conditions of water treatment facilities, agricultural irrigation lines, and chemical drainage systems, the Galv Backing Ring PN16 delivers the kind of secure, pressure rated connection that engineers and site managers can rely on. Designed to fit behind a stub flange, typically made from PVC or polyethylene, it locks two pipe ends together using bolts and a gasket, applying consistent bolting pressure that forms a tight, leak-resistant seal capable of handling up to 16 bar of nominal pressure.

Installation is straightforward. As a loose ring, it rotates freely around the pipe end, making it easy to align bolt holes precisely before tightening, no wrestling with fixed fittings or misaligned patterns. Its standard PN16 bolt hole spacing ensures compatibility with widely used industrial flanges, so it slots into existing systems without modification.

A zinc coating provides long lasting protection against rust and corrosion, making the Galv Backing Ring PN16 equally at home in wet environments, outdoor installations, and chemically exposed drainage lines. When the job calls for a backing ring that holds firm under pressure and stands up to the elements, this is the one to reach for.

Summary: 

• Used to join plastic or metal pipes together in a flanged piping system
• It works by applying bolting pressure onto a stub flange, creating a tight, secure seal that can handle pressures up to 16 bar
• It fits behind a stub flange (often made of PVC or polyethylene) to lock two pipe ends together with bolts and a gasket
• The PN16 rating means it is built to support systems running up to 16 bar of nominal pressure
• Because it is a loose ring, you can rotate it easily to line up bolt holes during installation
• Coated in zinc to stop rust and corrosion in wet or outdoor areas
• Features standard hole spacing to match PN16 industrial bolt patterns

Applications: 
Used in water treatment, agriculture, irrigation, and chemical drainage lines
