The McAlpine MS4 Multifit 90° Bend 1 1/4" is a push-fit plumbing fitting designed to create a right-angle turn in waste or soil pipework. It’s part of McAlpine’s Multifit range, which provides tool-free connections and flexible installation options in drainage systems.

Function & Purpose

This 90° bend allows two lengths of 1 1/4" pipe to be joined at a right angle, helping route waste pipework around corners, behind cupboards, under sinks, or through stud walls. The swept internal profile helps maintain smoother flow and reduces the risk of blockages compared with sharper-angled fittings.

Compatibility

The fitting is designed for 1 1/4" (32 mm) pipework, a common size for basin, sink, and bathroom waste connections. It works with compatible rigid waste pipe or flexible waste products used in domestic and light commercial installations.

Design & Build Quality

Manufactured to McAlpine’s quality standards, the MS4 90° bend features a robust body with secure push-fit seals that make installation quick and reliable without glue or solvent. The Multifit design allows the fitting to accept small variances in pipe dimension while maintaining a watertight connection.

Ideal Applications

This 90° bend is ideal for routing waste pipework in kitchen, bathroom, or utility areas where pipe direction needs to change sharply. It’s commonly used behind sinks and basins to guide the waste outlet toward the main drain, especially in tight spaces where a neat, compact turn is required.
