PEX Fittings

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

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.

Advantages

Direct Manifold Connection

  • The Eurocone end seats on the manifold outlet

No Welding or Pressing

  • Nut compression installation

Detachable

  • Separated by opening the nut during maintenance

Complementary Parts

  • The line is branched or closed with tees and plugs

Construction and Design Features

  • Brass body, nut and clamping ring
  • Eurocone or female-thread connection end
  • Ring specific to the pipe size
  • Mechanical connection tightened with tools

Send the pipe size (e.g. 16×2), connection type and quantity; we will confirm suitable PEX fittings from stock.

How to Choose?

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