PVC Reducer NICOLL 125/110 internal socket low-noise for drainage

NICOLL PVC reducer 125/110 internal socket low-noise for drainage is a compact transition fitting designed to connect 125 mm down to 110 mm PVC pipes in sanitary and wastewater systems. The internal socket construction provides a neat, space-saving joint while the low-noise design reduces sound transmission from fluid flow and discharge. This reducer is intended for use where a reliable diameter change is required without increasing external dimensions.

Advantages

The reducer offers stable, leak-resistant connections between different pipe diameters and is manufactured from PVC for chemical resistance and dimensional stability. Its internal socket form keeps the exterior line continuous and tidy, making it suitable for installation in confined or visible areas. The low-noise feature minimizes vibration and noise transfer along the drainage line, supporting compliance with building comfort and acoustic requirements.

Suitable for

• Building drainage systems in residential and commercial properties
• Sanitary and wastewater installations requiring diameter transition
• Renovation projects where existing 125 mm pipes must be adapted to 110 mm fittings
• Plumbing layouts with limited space or where external appearance matters

Key specifications

• Material: PVC (polyvinyl chloride)
• Connection type: internal socket reducer
• Input diameter: 125 mm
• Output diameter: 110 mm
• Function: low-noise drainage transition
• Application: sanitary and wastewater systems

How to use

Select the reducer matching the pipe diameters and align the 125 mm pipe into the larger socket and the 110 mm pipe into the smaller end. Ensure pipe ends are clean and free of debris; apply appropriate PVC solvent cement or recommended jointing method if required by the project or local codes. Push pipes fully into the sockets to the stop and allow any adhesive or sealant to cure before testing. Verify alignment and slope to maintain correct drainage flow.

Usage recommendations

For best results, handle the reducer and associated pipes according to local plumbing standards. Use compatible PVC solvent cement or gasket systems specified for internal socket connections, maintain correct fall for drainage, and avoid mechanical stress at the joint. Where acoustic performance is critical, combine low-noise fittings with proper pipe supports and isolation to further reduce vibration transmission.
