## Summary description

Flat union fitting SANHA type U1 with female 3/4" thread, galvanized for corrosion protection. Designed for joining pipes or components in plumbing and heating systems where a compact, detachable connection is required. Suitable for use in potable water, heating circuits and general installation where a threaded union connection ensures serviceability and tight sealing.

## Long description

SANHA flat union fitting type U1 with a female 3/4" thread is a compact, detachable connection element designed for plumbing and heating installations. The fitting is galvanized to provide surface corrosion protection and is shaped to achieve a flat union joint that allows easy assembly and disassembly without rotating connected pipes. It is suitable for potable water systems, heating circuits and general installation tasks where a threaded union offers serviceability and reliable sealing.
Advantages
The flat union design permits connection and disconnection of components without turning attached pipework, reducing installation time and mechanical stress. Galvanized surface treatment increases resistance to corrosion in typical indoor installation environments. The female threaded connection ensures compatibility with standard 3/4" male threads, providing a straightforward mechanical seal that is serviceable and can be tightened or removed as needed.
Suitable for
 Potable water supply lines
 Central heating circuits and radiators
 Plumbing installations requiring detachable joints for maintenance
 Connections between pipes and valves or other threaded components
Key specifications
 Type: flat union, model U1
 Thread: female 3/4" (compatible with standard 3/4" male threads)
 Material surface finish: galvanized for corrosion protection
 Connection form: detachable threaded union enabling serviceability
 Application environments: potable water systems, heating installations, general plumbing
How to use
Prepare mating threads by ensuring they are clean and free of debris. Apply an appropriate pipe thread sealant or PTFE tape to the male thread according to system requirements and local codes. Hand-start the female 3/4" thread onto the male fitting, then tighten using appropriate tools until a leak-free joint is achieved; avoid over-tightening to prevent damage to threads or sealing surfaces. For flanged or union alignment, ensure sealing faces are parallel and seated correctly before final tightening. After assembly, pressure-test the installation following applicable standards.
Usage recommendations
Use corrosion-resistant sealing materials and follow local regulations for potable water installations. Inspect the galvanized surface for damage before installation and avoid using the fitting in highly aggressive chemical environments without verification. Perform a pressure test after installation and schedule regular inspections as part of preventive maintenance.
