Geberit Mapress Stainless Steel Slip Coupling 15mm to 108mm

A Geberit Mapress 316 stainless steel slip coupling has no stop in the middle, so it can slide right along the pipe. That makes it the fitting for repairs and for putting a new piece into a run that is already fixed.

Why a Geberit Mapress 316 stainless steel slip coupling helps on repairs

With a normal coupling you need to spring the pipe apart to get it in. On stainless that is rarely possible. So you cut out the damaged section, slide the slip coupling back along the pipe, drop in the new length and slide the coupling over the joint. Then you press both ends. For example, a pipe damaged by a drill on a commercial fit-out can be sorted without stripping back half the run.

• Sizes: 15mm, 22mm, 28mm, 35mm, 42mm, 54mm, 76mm, 89mm and 108mm
• No centre stop, so it travels along the pipe
• CrNiMo 316 stainless steel 1.4401 body
• Press-Fit on both ends, with a pressing indicator

Because there is no stop, you need to mark where the coupling should sit. Put a pen mark on both pipes so the coupling is centred over the joint, then press. An unpressed joint will leak on the pressure test, so check every one. Use pressing tools and jaws that suit Mapress.

Common Questions

How far do I slide the slip coupling back?

Slide it fully onto one pipe end, drop the new length in, then draw it back until it is centred over the joint. Mark both pipes so you can see it is centred.

Can it repair a run in 89mm pipe?

Yes, it comes in 89mm and 108mm as well as the smaller sizes. The large sizes need the right press tooling.

Does it work on carbon steel pipe?

No, it is made for Mapress 316 Stainless Steel system pipe only. Geberit sell a separate Carbon Steel range, and the two must not be mixed on one joint.
