PEX Fittings

A PEX connection fitting is a brass compression fitting with a clamping ring that connects cross-linked polyethylene (PEX) or multilayer pipe to a manifold, valve or fitting.
It is used for underfloor heating manifolds, radiator supply lines and plumbing distribution. Eurocone 3/4″ and 1/2″ female-thread types are supplied for Ø16×2 and Ø17×2 mm pipes.
Main Applications
- Underfloor heating manifold connections
- Radiator supply lines
- Plumbing distribution manifolds
- In-wall PEX line connections
- PEX pipe joints in renovations
- Combi boiler and calorifier outlets

Material Options
| Part | Body | Nut | Clamping ring |
|---|---|---|---|
| Material | Brass (depending on model) | Brass (depending on model) | Depending on model |
| Surface | Natural or nickel plated (depending on model) | Natural or nickel plated (depending on model) | — |
| Connection | Eurocone 3/4″ or 1/2″ female thread | Hexagonal | Clamps the pipe to the body |
| Pipe | Ø16×2 / Ø17×2 mm | — | Specific to pipe size |
| Note | Chosen to suit the pipe size | Tightened with a wrench | Ring changes if pipe size changes |
Which material? When choosing a fitting the pipe outside diameter and wall thickness (e.g. 16×2 or 17×2) must match exactly; a ring of a different size spoils the seal.

How to Choose?
- Determine the pipe sizeRead the pipe outside diameter and wall thickness (16×2, 17×2).
- Choose the connection typeUse Eurocone for manifolds and female-thread fittings for valves and fittings.
- Plan the layoutAdd a PEX tee for branching and a plug for closing.
- Cut the pipe carefullyCut the pipe square and burr-free so it seats fully in the fitting.
