Plastic elbow 45° 25 mm Detal-met Kolano PP 45° 25mm

Detal-met Kolano PP 45° 25mm is a polypropylene 45-degree elbow designed for connecting 25 mm piping in domestic and light commercial plumbing and heating installations. The fitting provides a compact, angled change of direction for water supply, drainage, and low-pressure fluid circuits. It is compatible with common solvent-weld or push-fit installation methods depending on the piping system used, and is intended for straightforward integration into repair and new-build projects where a reliable elbow joint is required.

Advantages

The polypropylene construction offers chemical resistance and good mechanical durability while remaining lightweight. The 45° angle reduces flow disturbance compared with sharper turns and helps optimize routing in constrained spaces. Its 25 mm diameter matches standard small-bore piping, allowing consistent flow characteristics and easy replacement of existing components. Installation is simple when used with the matching joining method, and the fitting requires minimal maintenance in normal operating conditions.

Suitable for (tasks / use cases)

• Domestic water supply line alterations and rerouting
• Drainage and condensate lines in light commercial settings
• Low-pressure heating circuit connections and bypasses
• Plumbing repairs and retrofit work where a compact bend is needed

Key specifications

• Material: polypropylene (PP)
• Nominal angle: 45 degrees
• Nominal diameter: 25 mm
• Compatible joining: solvent-weld or push-fit (system-dependent)
• Intended fluid: water and low-pressure non-aggressive fluids
• Typical applications: plumbing, drainage, low-pressure heating circuits

How to use

Select the appropriate joining method for the existing pipework (solvent-weld or push-fit) and prepare pipe ends by cutting square and deburring. For solvent-weld systems, apply the recommended primer and solvent cement to the pipe and fitting per the adhesive manufacturer's instructions, assemble immediately and allow the joint to cure before pressurizing. For push-fit installations, ensure pipe ends are clean and fully inserted to the required depth until the joint engages. Verify alignment and support the piping to avoid undue stress on the elbow.

Usage recommendations

Use the fitting only within the pressure and temperature limits of the piping system and follow local plumbing codes. When replacing an existing elbow, confirm diameter and joining method compatibility. Provide mechanical support near the elbow to prevent movement and check joints periodically for leaks after installation and during initial operation.
