SANHA threaded union with gasket 15 x 1/2 — SANHA-Therm fitting

The SANHA threaded union with gasket 15 x 1/2 — SANHA‑Therm fitting is a mechanical connector designed for joining pipe sections or connecting fittings in plumbing and heating installations. It combines a threaded connection with an internal gasket to provide a reliable, serviceable joint. The coupling is intended for use in systems that accept 15 mm and 1/2" connections and is compatible with common pipe materials when installed according to manufacturer recommendations.

Advantages

This threaded union provides a removable connection that simplifies assembly and maintenance of piping systems. The integrated gasket improves leak resistance and reduces the need for additional sealing materials. The threaded design enables straightforward mechanical tightening without special tools, while the compact form factor fits into confined installation spaces. The fitting is suitable for both new installations and retrofit work where ease of disassembly is required.

Suitable for

• Connecting 15 mm to 1/2" pipe or fitting transitions in plumbing systems
• Joining copper, steel or multilayer pipes where compatible
• Domestic and light commercial heating circuits and hot water supply
• Repair, replacement or temporary connections requiring easy disassembly

Key specifications

• Connection type: threaded union with gasket
• Nominal size: 15 mm × 1/2" connection
• Seal type: integrated gasket for leak resistance
• Material: metal fitting suitable for plumbing and heating use
• Application environment: potable water and heating systems (following local codes)

How to use

Prepare the mating pipe ends by ensuring they are clean, deburred and free from scale or corrosion. Hand-start the threads to avoid cross-threading, then tighten the union by hand and finish with an appropriate wrench until the gasket compresses to form a seal; do not overtighten. Verify alignment of piping to avoid stress on the joint. After installation, pressure test the system according to applicable regulations and check the union for any signs of leakage.

Usage recommendations

Use only compatible pipe materials and follow the system’s temperature and pressure limits. Replace the gasket if the fitting is disassembled multiple times or if any damage is observed. Follow local plumbing codes and manufacturer installation guidance for sealing, joint preparation and testing.
