Adjustable Pipe Reducer 110/50, 45–88° angle, grey-green, No name (MPN HP/RN15)

Adjustable Pipe Reducer 110/50, 45–88° angle in grey‑green is a plastic fitting designed to connect a 110 mm pipe to a 50 mm pipe while allowing angular adjustment between 45° and 88°. The fitting compensates for differences in diameter and alignment, making it suitable for installations where pipe direction must change or where exact alignment is not possible with fixed fittings. The neutral grey‑green finish is appropriate for visible and concealed installations in drainage, waste and ventilation systems.

Advantages

This adjustable reducer provides a smooth transition between large and small diameter pipes and reduces the need for multiple elbows or additional fittings. The adjustable angle range allows installers to achieve correct alignment without complex cutting or jointing. Its durable plastic construction resists corrosion and is lightweight for easier handling and installation. The fitting is compatible with standard 110 mm and 50 mm pipe systems where a secure, sealed connection is required.

Suitable for

• Drainage systems where a 110 mm outlet must connect to 50 mm waste or branch lines
• Ventilation and soil stacks requiring angular adjustment between pipes
• Retrofit and renovation projects where existing pipe alignment differs from new components
• Temporary connections or test setups needing adjustable angle and diameter transition

Key specifications

• Connection diameters: 110 mm to 50 mm
• Adjustable angle range: 45°–88°
• Material: durable plastic (grey‑green finish)
• Application: drainage, waste and ventilation systems
• Compatibility: designed for standard 110 mm and 50 mm pipe profiles

How to use

Measure and mark the required insertion depths on both pipes and ensure pipe ends are clean and free of debris. Set the reducer to the approximate angle needed, then insert the 110 mm and 50 mm pipes into the respective ends until they reach the indicated depth or stop. Adjust the angle within the 45°–88° range to obtain correct alignment and secure the connection according to the pipe system’s sealing method (push‑fit, gasket, or solvent/weld where applicable). Verify alignment and test the system for leaks after installation.

Usage recommendations

Use appropriate sealing methods for the specific pipe material and local regulations. Avoid excessive mechanical stress or twisting after installation; support adjacent pipe runs to reduce load on the reducer. For long runs or pressurized applications, follow system manufacturer guidelines to ensure proper sealing and structural support.
