ALFA RK plumbing elbow PE female-thread 25×1 for pipe connections

ALFA RK plumbing elbow PE female-thread 25×1 for pipe connections is a right-angle polyethylene fitting designed to join PE pipes with internally threaded components. It features a 25 mm PE socket on one end and a 1" (25×1) female thread on the other, providing a compact and corrosion-resistant junction suitable for water supply and irrigation systems in residential and light commercial contexts.

Advantages

The fitting combines the flexibility and chemical resistance of PE with a standard internal thread, enabling secure transitions between plastic piping and threaded valves or fixtures. Its right-angle design saves space and simplifies routing where directional changes are required. The material choice reduces the risk of corrosion and mineral buildup, while the simple geometry supports straightforward installation and reliable sealing when paired with appropriate sealing materials.

Suitable for

• Domestic water supply lines using polyethylene pipe
• Irrigation systems and garden watering networks
• Connections to threaded valves, taps, and fittings in light commercial installations
• Retrofit projects where a threaded interface is needed on PE piping

Key specifications

• Connection type: PE socket to female (internal) thread
• PE socket diameter: 25 mm
• Female thread size: 25×1 (1 inch nominal internal thread)
• Elbow orientation: 90° right-angle
• Material: polyethylene (PE) body with threaded female connection
• Primary application: cold and potable water distribution, irrigation

How to use

Prepare the PE pipe by cutting squarely and deburring the end. Slide the pipe into the 25 mm PE socket until it seats fully; for a permanent joint, use the recommended fusion or electrofusion procedure appropriate for the PE material and local standards. When connecting to the female thread, ensure the mating male-threaded component is clean and in good condition. Apply a suitable thread sealant or tape to the male thread and tighten to the manufacturer's recommended torque to achieve a leak-free joint. Verify alignment and test the assembled connection under pressure following local installation codes.

Usage recommendations

Use this PE elbow where chemical resistance and corrosion-free performance are required. Do not expose the fitting to sustained temperatures or pressures beyond the limits specified for the PE piping system in use. For buried or concealed installations, follow appropriate backfill and protection practices. When joining with threaded metal components, confirm compatibility and use suitable sealing materials to prevent galvanic issues and ensure long-term tightness.
