Sink Trap McAlpine HC4PF-32 with metal strainer and rubber plug, 5/4x32

McAlpine HC4PF-32 is a sink trap designed for domestic washbasins and sinks with a 5/4x32 connection size. The unit combines a removable metal strainer that retains debris and a rubber plug for manual sealing of the outlet. Constructed for under-sink installation, the trap provides wastewater drainage and a water seal to help prevent sewer gases from entering the room while allowing straightforward access for cleaning and maintenance.

Advantages

The integrated metal strainer captures food particles and other solids, reducing the risk of blockages while remaining removable for cleaning. The rubber plug offers simple, tool-free sealing when required. The trap’s 5/4x32 connection fits a wide range of domestic basins and sinks, and the design allows easy disassembly for inspection or unblocking. Materials and finish are selected for corrosion resistance in normal household use.

Suitable for

• Kitchen sink installations where a removable metal strainer is needed
• Bathroom washbasins requiring a 5/4x32 waste connection
• Situations where periodic access to the trap chamber for cleaning is desired

Key specifications

• Connection size: 5/4 x 32 (suitable for standard domestic basin wastes)
• Containment: removable metal strainer to capture debris
• Sealing: rubber plug for manual outlet closure
• Installation location: under-sink application for kitchens and bathrooms
• Function: wastewater drainage with water seal for odor prevention

How to use

Install the trap directly beneath the basin waste, ensuring the 5/4x32 connection is tight and properly aligned with the sink outlet and drainage pipe. Place the metal strainer into the outlet to intercept solids; remove the strainer to clean accumulated debris and rinse before replacing. Use the rubber plug to manually seal the outlet when temporary water retention is needed; remove the plug to restore normal drainage. Follow standard plumbing practice to secure threaded joints and check for leaks after installation.

Usage recommendations

Periodically remove and clean the metal strainer to maintain drainage performance and reduce the chance of blockages. Avoid using aggressive chemical cleaners directly in the trap; if mechanical clearing is required, disassemble the trap as recommended and inspect seals before reinstallation.
