End Feed Slip Coupling 15mm WRAS Approved – Bag of 25

The 15mm end feed slip coupling is a straightforward but genuinely useful fitting for any plumber working on copper pipework. Unlike a standard end feed coupling, the slip coupling has no internal stop, which means the fitting can slide fully along the pipe in either direction. This makes it the go-to choice when repairing a section of existing pipework where you cannot pull the pipe ends apart far enough to fit a standard coupling. If you’ve ever tried to replace a corroded or leaking section mid-run, you’ll know exactly why this fitting exists.

Each bag contains 25 fittings, which makes this a practical buy for anyone doing volume repair work or wanting stock on the van. At 15mm, these are sized for standard household copper pipe and will suit the vast majority of domestic heating and plumbing repair jobs. The end feed design means you apply solder to the cup end of the fitting after assembly, giving a permanent, watertight joint when done correctly.

Why WRAS Approval Matters on an End Feed Slip Coupling

These 15mm end feed slip couplings carry WRAS approval, which stands for the Water Regulations Advisory Scheme. WRAS approval confirms that the fitting has been independently tested and is suitable for use in contact with drinking water in the UK. On any job involving potable water supply, using WRAS approved fittings is the right call, and on some contracts it is a requirement. It is also worth noting that most local water authorities and building control inspectors will want to see WRAS approved materials specified on new installs and significant repairs.

The fittings are manufactured to meet the dimensional standards expected from quality copper end feed fittings, giving a consistent fit on standard 15mm copper tube. Consistency matters when you are sweating multiple joints in a session, because you want the same amount of solder draw every time, not a lottery of tight and loose fits.

Bag Quantity for Trade Use

Buying in bags of 25 makes sense for anyone doing regular plumbing work. A single repair job might only need one or two slip couplings, but having a bag on the van means you are not caught short when a second issue shows up on the same visit. Keeping a stock of end feed slip couplings alongside standard couplings, elbows, and tees is the kind of sensible preparation that separates a well-equipped plumber from one making return trips to the merchant.

These fittings are suitable for use on domestic hot and cold water systems, central heating pipework, and general copper tube installations. They work with standard 15mm copper pipe to BS EN 1057 and are compatible with lead-free solder, which is the correct choice for potable water applications.
