McAlpine T25 Threaded Female Waste Connector 1.5″ BSP to 40mm / 43mm

McAlpine T25 Threaded Female Waste Connector 1.5″ BSP to 40mm / 43mm

Features

This genuine McAlpine T25 threaded female waste connector provides a direct bridge between mechanical threads and rigid solvent weld pipes. On one side, a free-spinning 1.5″ BSP female running nut connects straight to standard bath, kitchen sink, or shower waste outlets. On the opposite side, a smooth 43mm socket accepts standard 1.5″ plastic solvent weld pipe lines perfectly. Consequently, it creates a rigid, leak-proof transition zone without the need for angled elbows. Because it includes a high-grade rubber sealing washer, it locks tightly against male threads to ensure long-term, flood-free drainage performance.

• Genuine McAlpine fitting delivers professional, trade-tested reliability
• Converts a standard 1.5″ BSP male thread straight into rigid plastic pipe
• Smooth 43mm inner diameter socket fits UK 1.5″ solvent weld waste pipes
• Features a captive female spinning nut to prevent awkward pipe twisting
• Supplied complete with an internal rubber washer for a compression seal
• Ideal for eliminating restrictive 45-degree or 90-degree shower trap outlets

Details

Standard shower traps or kitchen outlets often ship with restrictive 45-degree or 90-degree elbow connections. Unfortunately, forcing these pre-fixed angles into a straight pipe run restricts your wastewater flow rate significantly. Furthermore, trying to glue a standard solvent pipe directly onto a mechanical drain thread is completely impossible. While nominal pipe measurements are called “1.5-inch”, the rigid solvent pipe actually measures a precise 43mm externally. Therefore, mismatching your compression nuts and solvent components leads to loose, weeping joints that slowly rot out subfloors.

Fortunately, this genuine McAlpine T25 threaded female waste connector resolves these plumbing layout issues cleanly. Because it features a straight profile, you can bypass awkward, pre-moulded trap elbows entirely. Instead, the 1.5″ BSP female spinning nut twists directly onto your trap outlet thread while the pipe remains static. Thus, the pre-installed rubber washer compresses tightly into place to stop leaks. Additionally, the opposite 43mm socket receives your rigid solvent pipe directly for a permanent weld. Consequently, you maximize water flow and achieve a straight, compact pipe run.
