The Polypipe Eurocone UFH Adaptor is the fitting that joins your underfloor heating pipe to the G¾" male Eurocone ports on a Polypipe Stainless Steel Eurocone UFH Manifold. It comes in two sizes: UFH12EC for 12mm pipe and UFH15EC for 15mm pipe. Each pack contains 2 adaptors (one pair), which is exactly what one circuit needs: one adaptor on the flow port and one on the return port.
Polypipe's Eurocone manifolds are built so the pipe size is chosen at the adaptor, giving flexibility in pipe size and system selection with fewer connections in the pipe run. Select the size that matches your pipe in the variant selector, then order one pack per circuit.

Compatibility: check before you order
These adaptors are for Polypipe Eurocone manifolds with G¾" male ports (UFH12752EC to UFH12762EC). They are not for Polypipe push-fit manifolds, which use a different connection. Choose the adaptor to match the outside diameter of your pipe: UFH12EC for 12mm, UFH15EC for 15mm.

How Many Packs Do I Need?
One circuit uses one flow port and one return port, so you need one pack of 2 adaptors for every circuit. The number of packs equals the number of manifold ports you are using.

Key Features
Sized to Your Pipe
UFH12EC takes 12mm pipe and UFH15EC takes 15mm pipe, so the same manifold can serve either system.
G¾" Eurocone Connection
Threads onto the G¾" male port of the Polypipe Eurocone manifold, the standard connection for the whole 2 to 12 port range.
One Pair per Circuit
Each pack holds 2 adaptors for the flow and return of a single circuit, which keeps ordering simple: packs = circuits.
Fewer Connections
Connecting the pipe through a Eurocone adaptor means fewer connections than building up the joint with extra fittings.
Matches Polypipe Packs
Polypipe's own Overlay manifold packs specify UFH12EC adaptors, so this is the correct part for 12mm Overlay circuits.
Full Manifold Range
Fits every size in the Polypipe Stainless Steel Eurocone UFH Manifold range, from 2 ports up to 12 ports.
Test before you cover
Pressure test every circuit and check each adaptor for leaks before screed or the floor build-up covers the pipe. Follow the Polypipe installation guide for the correct test procedure and pressure.

Frequently Asked Questions
Should I choose UFH12EC or UFH15EC?
Match the adaptor to the outside diameter of your pipe. Choose UFH12EC for 12mm pipe and UFH15EC for 15mm pipe. If you are unsure, check the size printed on the pipe or your underfloor heating design.
How many packs do I need for my manifold?
Order one pack per circuit. Each pack has 2 adaptors, one for the flow port and one for the return port. A 6 circuit system needs 6 packs, which is 12 adaptors in total.
Are Eurocone adaptors included with the manifold?
No. The Polypipe Eurocone manifold has bare G¾" male ports, so the adaptors are ordered separately to suit your pipe size. That is what lets one manifold work with 12mm or 15mm pipe.
Can I use these on a Polypipe push-fit manifold?
No. They are made for Eurocone manifolds with G¾" male ports. Polypipe push-fit manifolds use a different pipe connection.
Are these suitable for Overlay systems?
Yes for 12mm circuits. UFH12EC is the adaptor Polypipe specifies with its Overlay and Overlay Plus manifold packs, one pair per circuit.
Do the adaptors suit pipe from other manufacturers?
They are designed for Polypipe underfloor heating pipe at 12mm and 15mm. If you plan to use another make of pipe, confirm the outside diameter and suitability with the pipe supplier before ordering.
