Sink strainer screw ferrule McAlpine BSWFERRULE-41 41 mm

Replacement ferrule (screw for sink strainer) by McAlpine with a 41 mm diameter, designed to provide a secure threaded connection between a kitchen sink strainer basket and the waste assembly. The component is intended for use in repair or installation of compatible sink drain systems where a standard 41 mm ferrule is required. Made to fit common sink waste fittings, it restores the mechanical seal and stable attachment of the strainer to the drain.

Advantages

The ferrule offers a precise threaded interface that simplifies reassembly of the sink strainer and waste unit, helping to maintain a reliable mechanical connection. Its 41 mm diameter matches standard sink strainers, enabling straightforward replacement without modifying surrounding plumbing. The part is compact and easy to handle during installation, and it supports a leak-resistant connection when combined with the appropriate seal or washer.

Suitable for

• Repairing a kitchen sink strainer connection
• Replacement during waste assembly installation
• Maintenance of standard 41 mm sink drains
• DIY plumbing projects involving compatible waste fittings

Key specifications

• Diameter: 41 mm (compatible with 41 mm sink strainers)
• Function: Threaded ferrule / screw for securing strainer basket to waste assembly
• Material: metal (designed for mechanical strength and durability)
• Compatibility: standard kitchen sink waste fittings that accept 41 mm ferrules
• Application: replacement part for sink drain repair or installation

How to use

Disassemble the sink strainer and waste assembly to access the existing ferrule or screw. Remove the old ferrule and clean mating surfaces, verifying that the strainer basket and waste threads are free of debris and damage. Fit the replacement 41 mm ferrule onto the strainer tailpiece or waste thread, and hand-tighten to engage threads. Complete installation by tightening to the appropriate torque using suitable tools while ensuring an appropriate washer or seal is positioned to prevent leaks. After assembly, run water and inspect visually for any sign of leakage and retighten if necessary within manufacturer-recommended limits.

Usage recommendations

Use with compatible 41 mm sink strainers and a proper sealing washer. Inspect surrounding threads and surfaces for wear before installation; replace damaged parts to ensure a leak-free connection. Avoid overtightening metal ferrules to prevent thread damage—tighten until secure and test under normal water flow.
