Polyplumb Pipe Stiffeners - 15Mm (Pack Of 50)

Polyplumb Pipe Stiffeners - 15Mm (Pack Of 50)

The Polyplumb Pipe Stiffeners, 15mm (Pack of 50), are absolutely essential components for securing and guaranteeing the performance of any 15mm plastic push-fit plumbing system, particularly those using Polybutylene (PB) pipe. Often referred to as pipe inserts or spigots, these stiffeners are mandatory to maintain the circular shape and structural integrity of the plastic pipe where it enters the push-fit fitting.

Key Features and System Integrity
Essential Component: These inserts are not optional; they must be used in conjunction with all 15mm Polyplumb push-fit fittings (elbows, tees, couplings, etc.) to ensure a watertight seal.

Size and Compatibility: Designed specifically for 15mm plastic pipe (Polybutylene or PEX).

Function:

Maintains Shape: Prevents the soft plastic pipe from deforming or collapsing when inserted and compressed by the fitting’s grab ring and O-ring seal.

Secures the Seal: Provides a solid internal surface for the fitting's O-ring to press against, ensuring a leak-proof and pressure-tested connection.

Material: Durable high-quality plastic or metal, suitable for central heating and domestic water systems.

Quantity: Supplied in a convenient Pack of 50, offering excellent value for trade use and standard plumbing projects.

Compatibility: Designed for the Polyplumb system but often compatible with other major push-fit brands (always check manufacturer guidance).

The Installer's Advantage
Using the correct pipe insert is a non-negotiable step for compliance and safety in plastic push-fit plumbing. Having these 15mm Polyplumb stiffeners readily available ensures installers can work quickly and confidently, knowing every joint is mechanically sound and guaranteed, minimizing the risk of call-backs.
