SANHA flat union fitting U2 type, galvanized, female-male thread, model G3310025

The SANHA flat union fitting U2 type is a galvanized female-to-male threaded connector designed for creating a removable, sealed joint between threaded pipes or components. Model G3310025 provides a compact connection point that facilitates installation, maintenance and replacement in water and heating systems. The fitting’s flat union design allows disassembly without rotating the adjoining pipes, simplifying repairs and modular assemblies where space is limited.

Advantages

The galvanized surface offers corrosion resistance suitable for general plumbing and heating environments. The combination of a female and male threaded end enables direct connection to a range of standard threaded fittings, reducing the need for additional adapters. Its flat union construction permits easy separation of joined parts for maintenance or replacement while maintaining a reliable seal when assembled.

Suitable for

• Joining threaded pipes in domestic and commercial water supply systems
• Installation and maintenance of heating circuits and radiators
• Temporary connections during repair or system upgrades
• Modular assemblies that require periodic disassembly

Key specifications

• Material: galvanized metal suitable for plumbing use
• Design: flat union with removable joint
• Connection type: one female threaded end and one male threaded end
• Application: intended for water and heating systems
• Installation: threaded assembly, suitable for standard threaded fittings

How to use

Prepare the mating threaded pipe ends by cleaning threads and applying appropriate thread sealant or tape as required for the system media and local codes. Thread the male end into the female counterpart by hand until seated, then tighten to the recommended torque using suitable tools while avoiding over-tightening that could damage threads or deform the union face. To separate, loosen the threaded joint and pull the union halves apart; the flat union allows disassembly without rotating long pipe runs.

Usage recommendations

Use compatible thread sealants and observe system pressure and temperature limits. Verify material suitability for the specific water quality and heating medium. Inspect the sealing faces for debris or damage before assembly and perform leak tests after installation.
