The 15mm End Feed Slip Coupler joins two lengths of 15mm copper tube in a straight run with a soldered capillary joint. Unlike a standard coupler it has no internal tube stop, so it slides fully onto one pipe and back across the joint — ideal for repairs and for connecting two fixed pipes that can't be sprung apart. Common on 15mm radiator tails and hot and cold distribution. Manufactured from copper to BS EN 1254-1 and fits copper tube to BS EN 1057.

Also known as: slip coupling, repair coupler, repair coupling, slip socket, sliding coupler, no-stop coupler, slip fix coupler, endfeed slip coupler.

End feed means a capillary joint: clean the tube and fitting, apply flux, heat evenly and feed lead-free solder to the mouth of the fitting until a ring forms. See our guide: How to solder end feed fittings.
