Brass male threaded adapter Alkotest ŚZ2012 GZ 20 × 1/2 welded connection

Alkotest ŚZ2012 GZ 20 × 1/2 is a brass male threaded adapter designed for welded connection. The fitting provides a transition from a welded pipe or component to a G-type (BSPP) 20 × 1/2 external male thread, enabling secure mechanical connection to female threaded fixtures. Manufactured in brass, the adapter is intended for use in plumbing and heating systems where a welded joint and a standard BSPP male thread outlet are required.

Advantages

The brass construction offers good corrosion resistance and mechanical strength for typical domestic and commercial plumbing applications. The welded connection design ensures a permanent, leak-resistant joint to the pipe or component, while the standardized G-type male thread allows compatibility with a wide range of fittings and valves. The compact shape facilitates installation in confined spaces and supports reliable sealing when used with appropriate thread sealant or tape.

Suitable for

• Plumbing installations requiring transition from welded pipe to BSPP male thread
• Heating system connections where a welded joint and external thread are needed
• Repair or modification of pipelines and fixtures with G-type (BSPP) threaded components
• Applications in potable water, radiators, and general fluid distribution systems

Key specifications

• Material: brass
• Connection type (pipe side): welded joint
• Thread type: G (BSPP) external
• Thread size: 20 × 1/2 (G-type)
• Application areas: plumbing and heating systems

How to use

Prepare the pipe end for welding according to standard practice and ensure surfaces are clean and free of contaminants. Weld the adapter to the pipe following appropriate welding procedures and safety guidelines. After the weld has cooled, inspect the joint for completeness and any defects. Apply suitable thread sealant or PTFE tape to the male thread as required by the application, then connect the mating female threaded fitting and tighten to the recommended torque for the system to ensure a leak-free joint.

Usage recommendations

Use the adapter within the pressure and temperature limits of the system and ensure material compatibility with conveyed media. For installations involving potable water, verify that the brass alloy meets local drinking water regulations. When welding, follow safety procedures and welding standards to avoid creating stress or defects that could impair sealing or mechanical strength.
