Bronze 90° Elbow SANHA 4090, female thread 15 mm x 1/2" (MPN 140901512)

SANHA 4090 is a bronze 90° elbow with female threaded connections, sized for 15 mm to 1/2" pipe interfaces. It provides a compact right-angle transition between a 15 mm smooth pipe end and a 1/2" internal thread, enabling connection of copper or metal piping to threaded fittings in plumbing and heating systems. The fitting is manufactured from bronze to offer good corrosion resistance and mechanical strength for potable water and central heating applications where threaded joints are required.

Advantages

The bronze construction offers enhanced resistance to dezincification and corrosion compared with standard brass in demanding water and heating environments. The 90° geometry allows compact routing and space-saving installation where a right-angle change of direction is needed. Female internal threads provide secure, serviceable connections to standard 1/2" male-threaded valves, radiators, or fittings, while the 15 mm connection interfaces easily with copper or compatible metal pipe when joined by appropriate soldering or press methods.

Suitable for

• Domestic and commercial potable water systems
• Central heating and radiator connections
• Right-angle transitions between 15 mm pipework and 1/2" threaded fittings
• Plumbing repairs and retrofit work requiring a threaded coupling

Key specifications

• Material: bronze
• Angle: 90° elbow
• Connection types: 15 mm smooth pipe end to 1/2" female thread
• Application: potable water and central heating systems
• Suitable pipe materials: copper and compatible metal pipes

How to use

Prepare the 15 mm pipe end by cutting square and cleaning the surface according to the chosen joining method (soldering, brazing, or approved mechanical press/fit system). Apply appropriate thread sealant or tape to the male 1/2" thread before assembling into the elbow to ensure a leak-tight joint. Tighten the threaded connection to the torque recommended for the mating component; avoid over-tightening to prevent damage to threads. Inspect the assembled joint and perform a pressure test in accordance with local plumbing regulations.

Usage recommendations

Use this bronze elbow in systems where corrosion resistance and reliable threaded serviceability are important. Verify compatibility of joining methods and materials (solder flux, sealants, or press fittings) with bronze. Perform pressure and leak tests after installation and follow local codes for potable water and heating system installations.
