Hewalex reducer fitting HSA010012 for solar collectors, threaded female G1 x GZ1 connection

Hewalex reducer fitting HSA010012 for solar collectors, threaded female G1 x GZ1 connection is a hydraulic adapter designed for use in solar thermal installations. It provides a reliable transition between components with G1 and GZ1 female threads, enabling connection of collectors, pipes, valves or sensors where thread size conversion is needed. The fitting is intended for indoor and outdoor solar system plumbing where a compact threaded reducer simplifies assembly and reduces the need for additional adapters.

Advantages

The Hewalex threaded reducer offers a compact and sturdy solution for converting between G1 and GZ1 female threads without modifying existing piping. Its threaded female design ensures a tight mechanical connection compatible with standard solar thermal system components. The fitting reduces installation time by eliminating complex cutting or welding, and it supports maintenance operations by making disassembly and replacement straightforward. Materials and thread machining are selected to provide corrosion resistance and dimensional accuracy for leak-free connections under typical solar system pressures.

Suitable for

• Connecting solar collectors to piping with differing thread sizes
• Adapting valves, sensors or flow meters to existing female threaded ports
• Retrofit and repair work in domestic and small commercial solar thermal systems
• Hydraulic connections in collector arrays, manifolds and pump circuits

Key specifications

• Connection type: threaded female reducer
• Thread sizes: G1 to GZ1
• Application: solar thermal / hydraulic installations
• Compatibility: standard G-series BSP thread form used in solar plumbing
• Typical operating environment: potable and heat-transfer fluid circuits in solar systems

How to use

Ensure mating threads on pipes or components are clean and undamaged before assembly. Apply an appropriate thread sealant or tape compatible with the heat-transfer fluid in the system. Hand-start the fitting to avoid cross-threading, then tighten with an appropriate wrench until a secure, leak-free connection is achieved according to system pressure requirements and manufacturer torque guidance. When used externally on collectors or manifolds, check for correct orientation and access for maintenance. After installation, pressurize the circuit and inspect the joint for leaks.

Usage recommendations

Use thread sealants rated for the system fluid and temperature. During periodic system maintenance inspect threads and seals for wear or corrosion and replace the fitting if signs of degradation appear. For high-pressure or nonstandard fluid applications consult system documentation or a qualified installer to confirm suitability.
