Features

This genuine McAlpine 48mm trap waste extension adapter is a professional plumbing solution designed for kitchen sinks, baths, and shower drains.

Details

Identifying the correct replacement plumbing part can be highly confusing because traditional pipe sizes do not match actual tape measurements. For instance, a standard kitchen or bath waste is technically called a “1.5-inch” fitting, yet it actually measures roughly 48mm across the threads. Therefore, buying a part based on traditional naming often leads to receiving the wrong size. Furthermore, if your existing plastic sink thread was cut crookedly at the factory, a standard plumbing trap will sit unevenly. As a result, water will constantly drip into your cupboards, causing expensive wood damage.

Fortunately, this genuine McAlpine 48mm trap waste extension adapter resolves these measurement and leakage headaches instantly. Because the threads measure exactly 48mm in diameter, you can easily verify the fit with a standard ruler before purchasing. Once installed, its flat internal face and extra-thick rubber gasket flatten against your uneven drain pipe. Thus, as you tighten the nut, the rubber compresses deeply to fill any irregular gaps. Consequently, it creates a perfectly straight, watertight connection that stops leaks in seconds.
