Vekolux

Double connection fitting with drain-off facility for radiators with integrated valves, connection R1/2 and G3/4

The Vekolux double connection fitting is designed for installation onto radiators with integrated valves with an Rp1/2 female thread and a G3/4 male thread connection. The self-sealing connection makes the fitting easy to install on the radiator. Models in angle and straight forms, each designed for one- and two-pipe systems, mean that the connection fitting can be used in a number of different ways.

Features & Benefits

Complete radiator drain-off

Supply and return shut-off in one operation

For left and right connection to the radiator

Cover for angle and straight forms

All versions suitable for R1/2 and G3/4 connection
