Brewer Alkotest KZ2012 KOLANKO GZ FI20X1/2 — plumbing elbow fitting PP 20x1/2"

Alkotest KZ2012 KOLANKO GZ FI20X1/2 is a polypropylene (PP) 90° elbow designed for connecting 20 mm plastic pipe to a 1/2" threaded fitting. Intended for use in water supply and heating systems, this plumbing elbow provides a compact change of direction with a female threaded end and a male pipe socket, combining the chemical resistance of PP with a reliable mechanical connection for domestic and light commercial installations.

Advantages

The elbow is made of durable polypropylene that resists corrosion, scale and many common waterborne chemicals, ensuring a long service life in potable water and heating circuits. Its standardized 20 mm socket and 1/2" threaded interface allow straightforward integration with existing plastic piping and threaded fixtures. The 90° configuration enables space-saving routing and simplified jointing, while the molded design reduces the number of separate sealing elements required for installation.

Suitable for

• Domestic hot and cold water distribution
• Heating system connections and radiator inlets
• Plumbing repairs and retrofits in tight spaces
• Connections between plastic pipework and threaded valves or fittings

Key specifications

• Material: polypropylene (PP)
• Dimensions: 20 mm pipe socket to 1/2" threaded connection
• Configuration: 90° elbow
• Thread type: 1/2" male/female threaded interface (standard plumbing thread)
• Application: cold and hot water, heating systems
• Connection methods: push-fit/solvent/socket for pipe and threaded joint for fittings

How to use

Prepare the 20 mm pipe by cutting squarely and deburring the end, then clean the socket and pipe surfaces. Insert the pipe into the PP socket to the recommended depth; if required by the installation method, secure with the appropriate adhesive, sealant or mechanical fastening suitable for polypropylene systems. Apply suitable thread sealant or tape to the 1/2" threaded connection and tighten to the mating fitting without exceeding recommended torque to avoid distortion. Test the assembly for leaks at operating pressure before commissioning.

Usage recommendations

Use compatible PP piping and fittings and follow local plumbing codes. Avoid exposure to open flame and direct UV for prolonged periods; if installed outdoors, provide protection from sunlight. For hot-water or heating circuits, verify temperature and pressure ratings of the overall system components to ensure compatibility.
