BONFIX 2000440 – Straight reducing coupling alu-press (25 x 16)

Straight reducing coupling for clean pipe transitions

The BONFIX 2000440 is a straight alu-press reducing coupling for connecting 25 mm and 16 mm multilayer pipes. Working on an installation where a larger pipe needs to be reduced to a smaller diameter? This fitting offers a compact and reliable solution.

Suitable for potable water and heating systems

This press coupling is designed for potable water installations, heating systems, cooling water lines and dry compressed air systems. That makes it suitable for residential, commercial and renovation projects.

Why use a straight reducing coupling?

A straight reducing coupling allows two different pipe diameters to be connected directly. This keeps the installation clean, reduces the need for additional fittings and helps improve installation efficiency.

Added safety with Leak Before Pressed

BONFIX alu-press fittings include a Leak Before Pressed function. If the connection has not yet been pressed, this becomes visible during the pressure test. This helps installers identify incomplete pressings before the system is put into operation.

Durable material construction

The fitting body is made from brass and the press sleeve is made from stainless steel 304. EPDM seals provide reliable sealing performance. This material combination supports long term use in systems where pressure, temperature and reliability matter.

Compatible with multiple press profiles

The BONFIX 2000440 can be pressed with TH, H, U, F and CH profile jaws. This gives installers flexibility when working with common pressing tools on site.

Installation advice

Cut the pipe straight, calibrate and deburr it carefully, then push the pipe fully into the fitting. Check the correct position through the inspection window. The pressing process must be completed fully in one movement.
