Copper reducing tee SANHA 5130 35 x 18 x 35 mm

Copper reducing tee SANHA 5130 35 x 18 x 35 mm is a solder-type plumbing fitting designed to join three copper pipes where the branch requires a smaller diameter. Manufactured by SANHA from copper alloy, this reducing tee creates a permanent, leak-resistant connection after proper soldering. It is intended for use in potable water systems, heating circuits and refrigeration installations that require a transition from 35 mm main runs to an 18 mm branch.

Advantages

This SANHA reducing tee offers corrosion-resistant copper construction, compatibility with standard soldering techniques, and dimensional precision for reliable joints. The fitting’s concentric geometry ensures consistent flow characteristics and minimal pressure drop at the branch. Its material and manufacturing quality support long service life in potable water and closed heating systems when installed according to applicable standards.

Suitable for

• Domestic and commercial potable water distribution where a reduction from 35 mm to 18 mm is needed
• Central heating circuits and radiator branches requiring a smaller feed line
• Refrigeration and HVAC installations with copper pipe transitions
• Plumbing repairs and retrofits involving change of pipe diameter

Key specifications

• Material: copper alloy suitable for soldering
• Connection type: solder (capillary) joints for three pipes
• Sizes: main run 35 mm × branch 18 mm × opposite run 35 mm
• Geometry: reducing tee for concentric branch connection
• Typical applications: potable water, heating circuits, refrigeration lines

How to use

Prepare pipe ends by cutting square and deburring inner and outer edges. Clean mating surfaces and fitting sockets with appropriate abrasives or flux cleaners. Apply flux compatible with copper soldering to both pipe and fitting surfaces. Assemble the fitting onto the pipes, ensuring correct insertion depths and alignment. Heat the joint evenly with a suitable torch until the solder flows and produces a continuous fillet around each socket. Allow the assembly to cool naturally and then inspect each joint for full penetration and absence of gaps or voids. Finally, pressure-test the system according to local regulations before commissioning.

Usage recommendations

Use certified solder and flux materials appropriate for potable water where required, and follow applicable national plumbing codes. Ensure system is purged of contaminants prior to soldering and allow cooling time before applying pressure. For installations involving refrigerants or specialized heating fluids, follow manufacturer and industry safety guidelines.
