Bronze elbow SANHA 4090 90° female-threaded 22 mm x 3/4"

SANHA 4090 is a 90° bronze elbow with female (internal) threads in sizes 22 mm and 3/4". It is designed to change the direction of flow in plumbing and heating installations, allowing connection between a 22 mm copper or similar tube and a 3/4" threaded fitting. The fitting is manufactured from bronze to provide corrosion resistance and mechanical strength suitable for potable water, heating circuits and general hydraulic applications where a durable threaded elbow is required.

Advantages

The bronze construction offers increased resistance to corrosion and dezincification compared with standard brass in aggressive water conditions. Female-threaded design ensures secure connection to threaded components while the 90° angle enables compact direction changes in piping runs. The fitting combines metal-to-metal thread sealing compatibility with conventional sealing materials and provides reliable mechanical strength and thermal stability for standard plumbing and heating system temperatures.

Suitable for

• Domestic potable water installations
• Central heating systems and radiator connections
• Hydraulic assemblies requiring a 22 mm tube to 3/4" threaded transition
• Repair and retrofit work in existing piping systems

Key specifications

• Material: bronze
• Angle: 90° elbow
• Connections: 22 mm socket for tube and 3/4" female (internal) thread
• Typical applications: potable water, heating circuits, general hydraulic use
• Construction: threaded female fitting designed for metal thread seals with compatible sealing materials

How to use

Prepare the 22 mm tube end by cutting square and deburring the inner and outer edges. Apply appropriate thread sealant or PTFE tape to the male 3/4" thread of the mating component following the sealant manufacturer's instructions. Insert the tube into the 22 mm socket or connect the tube using the correct joining method for the system (e.g., soldered, compression or press connection as applicable), then engage the 3/4" male thread into the elbow's female thread and tighten to the required torque. Ensure alignment and support of connected pipes to avoid undue stress on the fitting.

Usage recommendations

Use compatible sealing materials for threaded metal connections and verify system pressure and temperature ratings before installation. Ensure the chosen joining method for the 22 mm tube is appropriate for bronze fittings and follow local plumbing codes and standards for potable water and heating systems.
