Underfloor Heating Pipe Fittings

What sizes are underfloor heating pipe fittings?

Most of these fittings are suitable for 16mm pipe as this is the most common size of UFH pipe. We do stock others sizes including 12, 15, and 17mm manifold adaptors.

Manifold Adaptors connect UFH pipe to ½“ thread on bottom of manifold.

Compression Fittings connect underfloor heating pipe together or to copper pipe.

• 16mm straight compression coupling – used for joining UFH pipe or repairing small sections.
• 16mm elbow compression coupling – allows an exact 90° bend
• 16mm – 15mm compression coupling – common for connecting to a radiator

underfloor heating pipe fittings come with an insert, olive and nut. This ensures connections are secure and reduces the possibility of leaks.
