Alkotest KW2012 KOLANKO GW FI20X1/2 pipe fitting PP elbow 20x1/2

Alkotest KW2012 KOLANKO GW FI20X1/2 is a polypropylene (PP) elbow pipe fitting intended for changing the direction of a pipeline while connecting a 20 mm pipe to a 1/2-inch threaded fitting. Designed for potable water supply and low-pressure HVAC systems, this PP elbow provides a corrosion-resistant alternative to metal fittings and is suitable for residential and light commercial plumbing installations.

Advantages

The polypropylene construction offers good chemical resistance, low weight and reduced risk of corrosion compared with metal alternatives. The elbow supports standard GW/fi threaded connections and provides a reliable joint with straightforward installation. Its smooth internal surface reduces flow resistance, and the material is compatible with common water system temperatures and pressures encountered in household and light commercial applications.

Suitable for

• Domestic potable water supply lines
• Bathroom and kitchen plumbing installations
• Low-pressure HVAC piping and circulation systems
• Light commercial plumbing where corrosion resistance is required

Key specifications

• Material: polypropylene (PP)
• Connection types: 20 mm socket to 1/2-inch standard threaded fitting
• Function: 90° elbow for changing pipe direction
• Application: cold and warm water distribution, low-pressure HVAC systems
• Properties: corrosion-resistant, lightweight, smooth internal bore

How to use

Prepare mating pipe and threaded fitting by cleaning contact surfaces and ensuring dimensions match the 20 mm socket and 1/2-inch thread. Insert the pipe fully into the PP socket and tighten the threaded connection to the recommended torque for the mating component, using appropriate thread sealant or tape if required by the system design. Verify alignment and support the piping to avoid mechanical stress on the elbow. Follow local plumbing codes and practices during installation.

Usage recommendations

Use this elbow in systems within the manufacturer’s recommended temperature and pressure limits for polypropylene fittings. Avoid exposure to aggressive chemicals not compatible with PP and provide mechanical protection where the fitting may be subject to impact or long-term UV exposure. When integrating with metal components, ensure compatible sealing materials and correct torque to prevent leaks.
