Geberit Mapress Stainless Steel Gas Reduced Branch Tee 22mm to 108mm

The Mapress Stainless Gas Reduced Branch Tee drops a smaller supply off a larger stainless gas run, in 17 sizes from 22mm x 22mm x 15mm up to 108mm x 108mm x 54mm, for Gas Safe registered engineers on commercial gas pipework. All three ends are press sockets with yellow seals.

Geberit make it from CrNiMo 316 stainless steel 1.4401 to EN 10088, with yellow HNBR seal rings, yellow marking and yellow protection plugs. Their datasheet lists natural gas, liquefied gas and biogas. It is silicone-free, and like the rest of the range it leaks if left unpressed, so a tightness test shows up any missed joint.

Sizes read run x run x branch. We carry branches from 15mm to 35mm on 22mm to 42mm runs, 54mm runs with 22mm, 28mm, 35mm or 42mm branches, and 76.1mm, 88.9mm and 108mm runs with a 54mm branch. Only use yellow-sealed Mapress gas fittings on gas; never swap in a black-seal water fitting because it fits the pipe.

Elbows and couplings for the job are in our Geberit Mapress Gas 316 Stainless Steel Press Fit section.

Common Questions

How can I tell a Mapress gas fitting from a water one? Gas fittings are marked yellow, with a yellow HNBR seal and yellow plugs. Water fittings have a black seal and clear plugs.

Who can fit the Mapress Stainless Gas Reduced Branch Tee? Work on a gas installation must be done by a Gas Safe registered engineer.

Which gases is it approved for? Geberit list natural gas, liquefied gas and biogas.

What if I forget to press a joint? Mapress fittings are made to leak if unpressed, so the tightness test will find it.
