McAlpine S28L-ISO Waste Pipe Adapter – 1 1/4″ UK to 32mm European Compression

McAlpine S28L-ISO Waste Pipe Adapter – 1 1/4″ UK to 32mm European Compression

Features

The McAlpine S28L-ISO Waste Pipe Adapter is an essential problem-solving plumbing fitting designed to seamlessly bridge the gap between different manufacturing standards. Featuring a dual-compression design, it is engineered specifically to connect European 32mm metric pipework straight to standard UK 1 1/4″ imperial plumbing.

Moulded from high-grade white polypropylene, this inline adapter features compression nuts and heavy-duty internal rubber seals on both ends. This allows you to join the slightly smaller European metric waste pipe to rigid UK domestic basin pipework securely without the use of solvent cement or specialized tools, ensuring a completely watertight transition.

• Genuine McAlpine fitting ensures trade-quality reliability and an absolute leak-free seal
• Dual-compression connection on both ends replaces the need for messy solvent welding
• Effortlessly adapts 32mm European metric pipework to standard UK 1 1/4″ imperial waste pipes
• Includes all necessary internal rubber sealing washers and grab rings for immediate setup
• Durable white polypropylene construction resists boiling water, impact, and chemical cleaners

Details

Installing an imported European bathroom vanity unit or a designer European space-saving trap kit often results in a major plumbing headache. While European waste pipework is a true metric 32mm, standard UK 1 1/4″ domestic waste pipework is slightly larger in diameter (typically measuring around 34mm to 36mm externally). Because the sizes are so frustratingly close but completely incompatible, standard UK couplers will slip and leak, while forcing the pipes together splits the plastic and causes structural-damaging water leaks beneath your floorboards.

The McAlpine S28L-ISO Compression Adapter completely eliminates this cross-border installation nightmare. With specialized, independent compression sockets on each side, it securely clamps onto the true 32mm European pipe on one end and grips the standard UK 1 1/4″ pipe on the other. It takes the guesswork out of international plumbing, giving you a clean, professional, and entirely watertight connection by hand in seconds.
