Underfloor heating pipes – PE-Xb/Al and PE-RT II/EVOH
Our underfloor heating range includes multilayer pipes in 500 m and 600 m coils, plus an adapter for connecting them. The category is intended for installers and contractors laying underfloor heating loops or installing radiator systems. The 16x2.0 mm pipes are available in two material constructions.
What you'll find in this category
- 16×2 PE-Xb/Al/PE-Xb pipe, 500 m coil: cross-linked polyethylene with an internal aluminium layer, size 16x2.0 mm.
- 16×2 PE-RT II/EVOH/PE-RT II pipe, 600 m coil: polyethylene with raised temperature resistance and an internal EVOH layer, size 16x2.0 mm.
- PEX 16×3/4" 6K29 adapter: brass, with a G3/4" thread and a 29 mm hexagon, supplied in packs of 2.
How to choose
- Internal pipe layer: choose a pipe with an aluminium layer (PE-Xb/Al/PE-Xb) or an EVOH layer (PE-RT II/EVOH/PE-RT II), depending on the project requirements.
- Pipe size: both pipes measure 16x2.0 mm. Check the outside diameter and wall thickness, as the fittings and manifold must be compatible.
- Coil length: choose from a 500 m or 600 m coil. Select the length to suit the total length of the loops and minimise waste.
- Adapter operating limits: the brass adapter operates at up to 70°C and 6 bar. It allows a glycol concentration of up to 50%.
- Connection thread: the adapter has a G3/4" thread. Make sure it matches the thread on the manifold or fitting.
Typical applications
The 16x2.0 mm pipes are used in cold and hot water systems and surface heating systems. They are also suitable for both low- and high-temperature radiator systems. The adapter connects a 16 mm pipe to a G3/4" threaded connection.
Frequently asked questions
What size are the pipes in this category?
Both pipes measure 16x2.0 mm. They differ in material and coil length: PE-Xb/Al/PE-Xb comes in a 500 m coil, while PE-RT II/EVOH/PE-RT II comes in a 600 m coil.
What are the operating parameters of the PEX 16×3/4" adapter?
The adapter is made of brass. Its maximum working pressure is 6 bar, its operating temperature is 70°C and its maximum glycol concentration is 50%. It has a G3/4" thread and a 29 mm hexagon.
