Keyplumb - Ufh Eurocone For 15Mm Pipe Underfloor

Keyplumb - Ufh Eurocone For 15Mm Pipe Underfloor

The Keyplumb 15mm Eurocone Connector is a precision compression fitting designed to connect 15mm plastic pipe (PEX or PERT) to an underfloor heating manifold or a radiator valve with a 3/4" Eurocone (EK) outlet.

While 16mm is the most common UFH size, 15mm pipe is frequently used in "overlay" systems or when tapping into existing domestic plumbing for small-area UFH (like a bathroom). This connector allows 15mm plastic pipe to interface perfectly with the standard 3/4" EK ports found on manifolds and mixing valves.

Key Features and Specifications

Pipe Compatibility: 15mm Outside Diameter (OD).

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

Material: Nickel-plated brass body.

Components: Includes the nut, a split compression ring, and a serrated tail insert with O-ring seals.

Standard: 3/4" EK (Eurocone) standard for leak-free mechanical jointing.

Common Applications

Manifold Connection: Connecting 15mm UFH loops to a standard manifold.

Radiator Plumbing: Connecting 15mm PEX or Polybutylene pipe to Eurocone-style radiator valves.

Retrofit Systems: Ideal for low-profile UFH systems that utilize 15mm pipework instead of the standard 16mm.

Installation Best Practices

Pipe Inserts: Ensure the serrated tail insert is pushed fully into the 15mm pipe.

Calibration: Even with 15mm pipe, using a calibration tool to re-round the pipe after cutting is recommended to avoid damaging the O-rings.

Torque: Tighten the nut onto the manifold thread by hand, then apply a final tighten with a spanner (usually a half-turn) to compress the split ring onto the pipe.

Compatibility Note: These are designed for plastic pipe; if you are trying to connect 15mm copper to a Eurocone port, you would typically use a different specialized copper-to-Eurocone adaptor.

Essential Companion Products

Manifolds: Stainless Steel UFH Manifolds.

Control: UFH Mixing Valve with Gauge.

Pump: Grundfos UPM3 Flex.
