## Summary description

McAlpine HC55 is a white mounting reduction connector designed to join or adapt pipe connections with diameters 6/4 x 5/4". Intended for use in plumbing and drainage systems, this connector provides a secure transition between mismatched pipe sizes and is suitable for domestic and light commercial installations requiring a compact reduction fitting.

## Long description

McAlpine mounting reduction connector HC55 6/4 x 5/4" white is a compact plastic fitting designed to provide a secure transition between two different pipe diameters in plumbing and drainage systems. The fitting is intended for situations where a 6/4" connection must be adapted to a 5/4" connection, offering a clean and simple means of joining mismatched pipe sizes in domestic and light commercial installations.
Advantages
The connector delivers a reliable mechanical connection without the need for extensive modification to existing pipework. Its white finish provides a neutral appearance suitable for visible plumbing under sinks or behind fixtures. The compact form factor saves space in restricted service voids and simplifies installation by reducing the number of separate parts needed for a reduction.
Suitable for
 Connecting a 6/4" pipe to a 5/4" pipe in sink, basin, or appliance drains
 Domestic plumbing repairs and small renovation projects
 Light commercial installations where compact reduction fittings are required
 Retrofitting or adapting existing drainage lines with mismatched diameters
When it may not be suitable
This plastic reduction connector is not designed for use with high-pressure water systems or applications that require metal fittings for mechanical strength or elevated temperature resistance. It may be unsuitable where local plumbing codes mandate specific materials or inspection access that the compact fitting does not provide.
Key specifications
 Material: durable plastic (white finish)
 Connection sizes: 6/4" to 5/4" reduction
 Application area: plumbing and drainage
 Installation type: push-fit or solvent/adhesive compatible depending on system (verify before installation)
 Typical use: domestic and light commercial installations
How to use
Before installation, verify the pipe diameters and the intended connection method. Prepare pipe ends by cutting square and removing burrs, then dry-fit the connector to confirm proper alignment. Depending on the pipe material and system, secure the joint using the recommended method for the system—push-fit engagement, sealing lubricant, or appropriate adhesive/sealant—following manufacturer guidance and local codes. After assembly, check the joint for alignment and perform a leak test at operating pressure.
What to consider before purchase
 Confirm the exact pipe diameters to ensure compatibility with a 6/4" to 5/4" reduction
 Check local plumbing regulations for permitted materials and fitting types
 Determine whether the installation requires additional seals, clamps, or adhesives
 Assess space constraints to ensure the connector's compact size fits the service area
Usage recommendations
Use the McAlpine HC55 in low-pressure drainage and waste applications where a clean, compact reduction is needed. Always follow pipe manufacturer and local code instructions for joint preparation and sealing, and test the connection for leaks after installation.
