PP 90° elbow fitting 25 mm Detal-met KOLN90/25

Detal-met PP 90° elbow fitting 25 mm is a polypropylene pipe connector engineered to change the flow direction by 90 degrees in plastic piping systems. Designed for use with 25 mm diameter polypropylene and other compatible plastic pipes, this compact elbow provides a corrosion-resistant joint for low-pressure water supply, drainage, irrigation and HVAC applications. The fitting is intended for systems where a durable thermoplastic connection is required and where space constraints call for a neat, angled turn.

Advantages

The polypropylene construction ensures chemical resistance, low weight and long service life compared with metallic alternatives. Its smooth internal surface reduces flow resistance and limits debris build-up, while the uniform 90° angle provides predictable hydraulic behavior. The fitting is easy to handle and install, and its compact design minimizes the space needed for pipe routing when changing direction.

Suitable for

• Low-pressure potable and non-potable water supply lines with 25 mm plastic piping
• Drainage and waste piping in residential and light commercial installations
• Irrigation systems and garden water distribution where 25 mm pipes are used
• HVAC condensate and low-pressure ventilation drains compatible with polypropylene

Key specifications

• Material: polypropylene (PP)
• Angle: 90 degrees
• Designed pipe diameter: 25 mm
• Application: low-pressure fluid conveyance (water, waste, irrigation)
• Surface: smooth internal bore to reduce flow resistance
• Weight: lightweight thermoplastic construction for easier handling

How to use

Prepare pipe ends by cutting square and deburring to ensure a clean fit. Ensure the mating pipe is compatible with polypropylene fittings and meets the required outside diameter of 25 mm. Insert the pipe fully into the fitting until it seats; when using solvent-weld or heat-fusion methods follow the pipe and fitting manufacturer instructions and local plumbing standards. After assembly, test the joint at working pressure and inspect for leaks before burying or concealing the connection.

Usage recommendations

Use the fitting in applications within the temperature and pressure limits suitable for polypropylene. Avoid exposure to direct flame and prolonged UV radiation without protective measures. For pressurized potable water systems confirm compliance with local regulations and use recommended joining methods for reliable, leak-free connections.
