Sink trap extension McAlpine RS6 with flange 5/4" x 32 x 180 mm, chrome

McAlpine RS6 sink trap extension is a chrome-finished pipe adapter with an integrated flange, sized 5/4" x 32 x 180 mm. It is designed to extend or connect washbasin siphons, providing additional length and a secure flanged connection to align fittings and maintain reliable drainage. The chrome surface offers a smooth, corrosion-resistant finish intended for visible installations beneath basins.

Advantages

This sink trap extension provides a precise additional length to standard washbasin piping while maintaining a sealed connection via its flange. The chrome finish resists staining and is easy to clean, supporting both domestic and light commercial environments. Its dimensions allow compatibility with typical basin trap outlets and downstream pipe runs, helping to simplify installation and reduce the need for joint bending or improvisation.

Suitable for

• Extending washbasin siphon connections where extra length is required
• Replacing a short or damaged trap connector under sinks
• Installations requiring a flanged connection for secure sealing
• Visible plumbing runs where a chrome finish is preferred

Key specifications

• Material finish: chrome-plated surface for corrosion resistance
• Connection type: flanged end for sealed attachment
• Size: nominal 5/4" connection to 32 mm pipe diameter with 180 mm overall length
• Application: designed for washbasin/ sink trap extension use

How to use

Measure the required additional length between the existing washbasin trap outlet and the downstream inlet to confirm that the 180 mm extension provides the needed reach. Ensure mating surfaces are clean and free of debris, then fit the flanged end onto the trap outlet and secure according to the sink trap assembly method in use (compressing a washer, tightening a slip nut, or using a compatible coupling). Confirm alignment to avoid strain on adjoining fittings and test the connection by running water and checking for leaks.

Usage recommendations

Use the extension in conjunction with compatible trap fittings and appropriate washers or sealing rings. Do not overtighten mechanical joints to prevent damage to threads or chrome plating. For installations in commercial or high-use environments, periodically inspect joints and the chrome surface for signs of wear or corrosion and replace components as needed.
