Solder Ring Coupler 8mm to 67mm

A Solder Ring Coupler is a straight copper connector with a ring of solder built into each end. Heat it with the pipes in place and the solder runs into the joint, so you do not need to feed extra wire.

Using a Solder Ring Coupler

This is the fitting you use most on copper: joining lengths, putting in a repair, or connecting new pipe to old. The small 8mm, 10mm and 12mm sizes suit microbore and old imperial work. 15mm to 28mm cover everyday water and heating, and 35mm to 67mm handle larger mains and commercial pipework.

• Sizes: 8mm, 10mm, 12mm, 15mm, 22mm, 28mm, 35mm, 42mm, 54mm and 67mm
• Copper, straight coupling
• Solder Ring built into each end
• Has a pipe stop in the middle

Square and deburr the pipes, then polish the pipe end and the fitting socket with wire wool until they shine. A thin coat of flux goes on the pipe only. Push the pipes in, heat the fitting rather than the pipe, and stop once the solder shows as a full ring at each mouth. Let it cool before moving it. The full range sits under Solder Ring fittings.

Common Questions

What is a solder ring coupler? It’s a straight copper fitting that joins two lengths of copper pipe of the same size. The solder is already inside the fitting, so you don’t need to add any.

How do I solder a solder ring coupler? Clean the pipe ends and the inside of the fitting, apply flux, and push the pipe in fully. Heat the joint until you see the solder appear round the mouth, then let it cool naturally.

Can I use a solder ring coupler on plastic pipe? No, this coupler is for copper pipe only, as plastic can’t take the heat needed to make the joint. For plastic pipe, use a push-fit fitting instead.

Can I reuse a solder ring coupler? Not really, because once the solder has run the ring is used up. If a joint has to come apart, cut it out and fit a fresh coupler.

What sizes do solder ring couplers come in? We list them from 8mm all the way up to 67mm, which takes in the 15mm and 22mm sizes you’ll find in most houses.

Is the solder in the coupler lead-free? Yes, the built-in solder ring uses a lead-free formulation.
