Flexible Rubber Tee 1 1/2 inch to 4 inch

A Flexible Rubber Tee lets you take a branch off a waste, soil or drainage pipe without solvent welding or matching a particular pipe system. Each end slips over a plain pipe and is clamped tight with a worm drive clip.

What it’s used for

These come out when the pipes don’t match. Picture an old cast iron stack with a new plastic branch, a run where the existing pipe has an odd outside diameter, or a quick repair where you can’t get a proper fitting in. Because the body is flexible it will take up a little misalignment between the three pipes, though it’s no substitute for setting the pipes out properly. Rubber connectors like this are for gravity drainage, not pressurised water.

Sizes available

Sizes are nominal inch sizes. Measure the outside of each pipe before you buy, as old imperial pipe and modern metric pipe don’t always line up, and a clip can only close a connector down so far.

Fitting tips

Cut the pipe ends square and clean off any loose rust, scale or old sealant so the rubber seals on a smooth surface. Push each pipe fully into the tee, then tighten the clips evenly with a screwdriver or nut driver. Don’t overtighten and cut into the rubber. Support the pipes either side so the tee isn’t carrying their weight. If it doesn’t come with clips, or you need spares, we sell Jubilee clips in the same section. Take a look at our full flexible rubber connectors range for couplings, caps and elbows too.

Common Questions

Can I tee a plastic branch into an old cast iron pipe with this?

Yes, provided you can cut a section out of the iron pipe to fit the tee. The rubber ends clamp onto each pipe, so iron and plastic can meet in the same fitting.

Does a rubber tee need its own support?

Yes. Bracket the pipes close to each leg so the tee is only sealing, not holding pipes up. A heavy branch left hanging on the rubber will drop over time.

Is this suitable for a pumped waste?

No. Flexible rubber connectors like this are for gravity drainage, so keep them off pumped or pressurised pipework.
