FloPlast Solvent Soil Double Socket Coupler – SS106 110mm

Glued stacks are lengthened with the FloPlast Solvent Soil Double Socket Coupler SS106, which joins two plain ends of 110mm solvent soil pipe in a straight line. Both ends are solvent sockets.

Jobs for the FloPlast Solvent Soil Double Socket Coupler SS106

It lengthens a stack past a single pipe, or reconnects an offcut into the line. For a cracked length, two of these let you cut out the bad section and cement in a replacement piece.

Cut the pipe square and deburr it. Pencil the insertion depth onto each pipe, brush cement on both faces, then push in and turn slightly before holding still.

Clip the stack close to the coupler. Solvent joints are rigid, so the stack needs proper support to avoid strain.

Work in dry conditions where you can, since damp surfaces weaken a solvent joint. In cold weather, give the cement longer to set before testing.

Common Questions

What is a double socket pipe coupler? It joins two plain ends of pipe in a straight line. The FloPlast SS106 has a solvent socket at each end for 110mm solvent soil pipe, and it’s also the go-to fitting for cutting in a repair.

Can you solvent weld 110mm soil pipe? Yes, FloPlast’s solvent soil range is designed to be solvent welded. Just don’t put cement on ring seal fittings, as they rely on the rubber seal.

How do I solvent weld soil pipe? Cut the ends square and deburr them, coat both surfaces with SC125 or SC250 cement, then push the pipe fully home and hold it still briefly. FloPlast suggest waiting 2 to 3 hours before short discharges and 24 hours before continuous flow.

Is all soil pipe solvent weld? No, there are ring seal systems too, which push together with a rubber seal and lubricant. The SS106 is for the solvent weld range, so check which type you’ve got before buying fittings.

Can I use the SS106 outside? Yes, FloPlast describe their solvent soil as UV resistant, so it’s fine on an outside stack.

Is it hard to fit a double socket coupler into an existing stack? It can be awkward to get both pipes into the sockets when the stack is fixed. The SS107, with one solvent and one ring seal socket, makes that easier and lets the joint move for expansion.
