McAlpine T12A-F Flush Waste Thread Adaptor — 1.5″ BSP Male to Female Spigot

Features

This genuine McAlpine T12A-F flush waste thread adaptor is a specialist problem-solving fitting designed for kitchen sinks, baths, and shower drains. It features identical 1.5″ BSP threads on both ends, with a captive female nut on top and a flush male spigot below. Consequently, it works perfectly as an ultra-short extension piece for tight spaces. Additionally, it is uniquely suited for fixing uneven or poorly cut waste threads. Because it utilizes an extra-thick rubber sealing washer against a flat internal face, it creates a completely watertight seal even on irregular plumbing joints.

Details

Installing a new kitchen waste or bath drain can quickly reveal manufacturing flaws. For example, plastic threads on cheap sinks are often molded unevenly or cut out-of-square at the factory. Therefore, when you attempt to screw a standard plumbing trap onto these flawed threads, the joint sits crookedly. As a result, water continuously drips down the side, potentially rotting out your floorboards. Redoing the entire waste system because of one poorly cut thread is a incredibly frustrating and costly problem.

Fortunately, this genuine McAlpine T12A-F flush waste thread adaptor resolves these uneven thread defects instantly. Because it features a flat internal sealing face paired with an extra-thick rubber washer, it accommodates crooked surfaces easily. Thus, when you tighten down the top nut, the heavy-duty rubber compresses deeply to fill any irregular gaps. Furthermore, it creates a perfectly true 1.5″ male connection point below. Consequently, your trap connects straight and true, stopping troublesome leaks in seconds without messy sealants.
