McAlpine S12A-F Trap & Waste Thread Extension Adapter – 1 1/4″

Features

The McAlpine S12A-F Trap & Waste Thread Extension Adapter is a versatile, trade-quality fitting designed to solve tricky bathroom basin plumbing issues. Featuring a standard 1 1/4″ BSP thread, this multi-purpose component can be used as a short fixed extension piece to bridge awkward gaps between your waste and trap, or as an adapter for irregular or extra-thick waste threads that standard traps won’t grip.

Moulded from high-grade white polypropylene, it features a specialized flat internal face loaded with a thick, heavy-duty sealing washer. This unique design creates a secure, water-tight seal on non-standard fittings, leaving the male-threaded bottom end perfectly prepped to accept any standard 1 1/4″ waste trap.

Details

When installing unique designer basins, thick ceramic sinks, or non-standard waste kits, you often find that the waste thread is too short, too thick, or irregularly shaped for a standard trap to screw onto properly. Forcing a standard fitting onto a mismatched thread results in cross-threading, ruined plastic, and slow, destructive leaks hidden inside your vanity cupboard.

The McAlpine S12A-F Adapter eliminates this plumbing nightmare. Its specialized flat-face interior and extra-large washer crush down onto irregular or short threads to form a perfectly flat, watertight seal. It effortlessly converts problematic pipework into a standard, universal 1 1/4″ male thread, allowing you to spin your trap into place in seconds without leaks, mess, or stress.
