Weld-on coupler 16, Continuous thread, Rp 3/8, Length 26 mm - Riegler 113286

Weld-on coupler 16, Steel with a bare metal surface ST 37-2, Continuous thread, Rp 3/8, Length 26 mm, Working pressure max. 50 bar The steel fittings are made of tubular steel to DIN 2441 and boast good resistance to mechanical stresses. Hot dip galvanised steel fittings are completely coated with a layer of pure zinc and are therefore protected against rust. They are used in pipe construction, plumbing and gas installations as well as a wide range of industrial applications, especially in conjunction with the popular malleable iron series.

About Steel fittings

Steel fittings extend, join and reduce threaded lines wherever mechanical loads are involved. All of them are rated for a working pressure of 50 bar and the range covers threads from R 1/4 up to R 3 male.

What matters when choosing

• Thread size follows the pipework. Male threads run from R 1/4 to R 3, female ones are available as Rp 1/4 and Rp 3/8.
• On double nipples the overall length decides how far the gap is bridged. Lengths from 25 to 200 mm are offered in steps.
• The finish follows the surroundings. Galvanised ST 37-2 steel is protected against rust, while bright ST 37-2 and black steel suit places where that coating is not needed.
• Maximum working pressure is the same 50 bar across all 147 items, so combining individual fittings involves no mixed pressure ratings.

Typical applications

• Pipework built with threaded joints
• Extending and spacing valves and manifolds
• Compressed air distribution in workshops and halls using steel pipe
• Repair work on existing threaded lines where single sections are replaced
• Connecting shut-off cocks and strainers in supply lines

Threads are made to ISO 7-1 and EN 10241, the base material is steel tube to DIN 2441. Galvanised versions are fully covered with a pure zinc layer and thus protected against rust.
