Polyplumb UFH Eurocone Adaptor - 15mm Pair

Polyplumb UFH Eurocone Adaptor - 15mm Pair

The Polyplumb 15mm Eurocone Adaptors are high-specification compression fittings designed to connect 15mm polybutylene or PEX pipe to an underfloor heating manifold. This "Pair" pack is specifically intended for a single UFH loop (providing the connection for both the Flow and the Return ports).

These adaptors utilize the universal 3/4" Eurocone (EK) thread, ensuring compatibility with almost all modern stainless steel or brass manifolds. They are engineered to provide a robust, mechanical joint that handles the constant thermal expansion and contraction cycles typical of underfloor heating systems.

Key Features and Specifications

Quantity: Pair (2 Fittings).

Pipe Compatibility: 15mm Outside Diameter (OD) plastic pipe (Polyplumb, Polyfit, or PEX).

Thread Size: 3/4" Eurocone (EK) Female.

Material: Nickel-plated brass for durability and corrosion resistance.

Seal Design: Features a high-performance EPDM O-ring and a split-ring compression collar to grip the pipe securely.

Standard: Manufactured to interface with 3/4" EK manifold outlets.

Common Applications

Standard UFH Loops: The go-to fitting for connecting 15mm plastic pipework to a central UFH manifold.

Radiator Manifolds: Often used in "point-to-point" plumbing where a manifold is used to distribute water to individual radiators via 15mm plastic pipe.

System Repairs: Replacing older or leaking manifold connectors.

Installation Best Practices

Pipe Inserts: You must use a 15mm pipe insert (stiffener) inside the plastic pipe before fitting the adaptor. This prevents the pipe from collapsing when the compression nut is tightened.

Square Cut: Use a sharp pipe cutter to ensure a perfectly square end. A jagged or angled cut can lead to an uneven seal.

Seating the O-ring: Ensure the pipe is pushed fully home into the adaptor body so the internal O-ring creates a watertight seal against the pipe wall.

Tightening: Hand-tighten onto the manifold port, then apply a final tighten with a spanner (usually a half to three-quarters turn). Over-tightening can damage the manifold's seating face or the adaptor's O-ring.

Essential Companion Products

Pipe Inserts: 15mm Plastic Pipe Inserts (Essential for a safe joint).

Manifolds: Stainless Steel UFH Manifold.
