FloPlast Ring Seal 92.5 Deg Bend Socket/Spigot – SP161 110mm

The FloPlast Ring Seal 92.5 Deg Bend Socket/Spigot SP161 turns a 110mm soil pipe through a little more than a right angle, with a socket carrying a rubber seal and an unsocketed spigot as its other end.

Fitting the FloPlast Ring Seal 92.5 Deg Bend Socket/Spigot SP161

The spigot goes straight into the next fitting’s socket, keeping the bend compact. The extra few degrees build a small fall into a horizontal leg coming off a drop. It is a common choice on WC runs.

Bevel any cut ends, grease them with silicone, seat the pipe and back it out a fraction. Make sure the extra angle tilts the run downhill towards the drain.

It is not the bend for the foot of a stack, where FloPlast advise a long radius rest bend or two 45 degree bends. Keep a rodding point within reach.

Do not use solvent cement on Ring Seal joints, as it damages the seal.

Common Questions

Why are soil pipe bends 92.5 degrees? The extra angle builds a small fall into the horizontal leg, keeping waste moving towards the drain. Make sure you fit it so that tilt points downhill.

Can you solvent weld push fit soil pipe? No, ring seal joints like the SP161 use silicone lubricant only. Solvent cement damages the rubber seal.

How do I fit push fit soil pipe into the SP161? Bevel the cut end, grease it with silicone lubricant, push it home, then ease it back a fraction for expansion. The spigot end goes straight into the next fitting’s socket.

Is the SP161 good for a WC run under the floor? Yes, it’s a common choice where the WC pipe turns under the floor towards the stack. Keep a steady fall and support the pipe on both sides.

How does a socket/spigot bend differ from a double socket bend? One end has a ring seal socket and the other is a plain spigot, so it can plug directly into another fitting. That keeps the turn compact and saves a short length of pipe.

How hot can the waste be? It’s rated for 70°C to 75°C continuous discharge, with hotter flows for no more than 2 minutes at a time.
