McAlpine articulated extension 32x32 mm chrome P-300-FLEXCP-RS9 siphon accessory

The McAlpine articulated extension 32x32 mm chrome P-300-FLEXCP-RS9 siphon accessory is a flexible, chrome-finished connector engineered to adapt drainage layouts where direct alignment is not possible. It provides an adjustable joint between 32x32 mm drain components to correct misalignment and simplify connection of sinks and basins. The chrome surface offers a corrosion-resistant appearance suitable for visible plumbing under washbasins and kitchen sinks.

Advantages

This articulated extension allows angular adjustment to bridge offsets without the need for cutting pipes or repositioning fixtures. The quick-fit design reduces installation time and the chrome finish resists corrosion and staining in typical domestic environments. Its compact form factor fits within standard trap and tailpiece assemblies, preserving under-sink space while enabling reliable joint movement.

Suitable for

• Adjusting misaligned sink or basin drain connections
• Retrofit installations where existing piping cannot be easily moved
• Domestic bathroom and kitchen sinks with 32x32 mm connections
• Situations requiring a chrome-finished visible fitting

When it may not be suitable

This articulated extension is intended for use with 32x32 mm drainage systems; it is not suitable for sizes or systems with different diameters. It is designed for typical domestic drainage conditions and may not be appropriate for high-pressure or industrial drainage applications. For concealed installations requiring solvent-welded or rigid connections, a fixed coupling may be preferable.

Key specifications

• Connection size: 32 x 32 mm
• Type: articulated/adjustable extension for siphon connections
• Surface finish: chrome plated, corrosion-resistant appearance
• Application: sink and basin drainage alignment and adaptation

How to use

Fit the articulated extension between the existing siphon/trap and the tailpiece or waste outlet by sliding each end onto the corresponding 32x32 mm connections and securing according to the trap manufacturer’s instructions. Adjust the joint angle to achieve correct alignment, then tighten any compression fittings or clips to ensure a watertight connection. Test the assembly for leaks by running water and checking joints; readjust and retighten if necessary. Ensure there is adequate seal material where required by the connected components.

What to consider before purchase

• Confirm that both mating components use 32 x 32 mm connections
• Verify that a visible chrome finish is acceptable in the installation area
• Check compatibility with the existing siphon or trap type (compression, push-fit, etc.)
• Assess whether an adjustable joint is preferable to a fixed coupling for long-term stability

Usage recommendations

Use the articulated extension to correct minor misalignments and simplify retrofit installations. After installation, run a full flow test and inspect periodically for signs of loosening or wear, especially in installations subject to frequent movement or heavy use.
