Reducer pipe fitting MAGNAPLAST Ultra dBR 110/75 (Ø110 to Ø75)

MAGNAPLAST Ultra dBR 110/75 reducer pipe fitting is a PVC transition piece engineered to connect a 110 mm diameter drain or sewer pipe to a 75 mm pipe. Designed for use in residential and commercial drainage systems, this reducer maintains hydraulic flow between different pipe sizes while providing a reliable, smooth internal profile to minimise turbulence and blockages. The component is suitable for both underground and above-ground installation where compatibility between standard 110 mm and 75 mm piping is required.

Advantages

The fitting offers a secure, watertight connection between dissimilar pipe diameters without the need for complex adapters. Its PVC construction resists corrosion and chemical degradation common in drainage environments, and the internal contour reduces the likelihood of sediment accumulation. The compact design facilitates installation in confined spaces and helps maintain consistent flow characteristics across the junction.

Suitable for

• Domestic waste and stormwater drainage systems
• Commercial and light industrial sewer branches
• Underground drainage connections and manhole interfaces
• Above-ground plumbing runs where diameter reduction is necessary

Key specifications

• Material: PVC suitable for drainage applications
• Input diameter: 110 mm
• Output diameter: 75 mm
• Type: concentric reducer for smooth internal transition
• Application: gravity drainage and sewer systems

How to use

Before installation, verify pipe diameters and clean contacting surfaces to remove debris and grease. Apply a compatible PVC solvent cement or gasket sealing method recommended for the specific piping system, then insert the smaller and larger pipes into the respective ends of the reducer until fully seated. Ensure correct alignment and slope for gravity flow, and allow any adhesive or seal to cure according to the manufacturer's instructions before pressurising or commissioning the system.

Usage recommendations

Use this reducer in gravity-fed drainage systems where a controlled transition from Ø110 to Ø75 is required. Avoid exposure to direct flame and incompatible solvents. For underground installations, ensure proper bedding and backfill to prevent point loads on the fitting; for above-ground use, provide mechanical support where spans or thermal movement could stress joints.
