VIEGA Rotguss Double Nipple 1/2″ Male x Male Thread, Gunmetal (Brass Alloy), Art. 266592

Description

The VIEGA Rotguss double nipple (model 3280, article 266592) is a short, straight connector with an external (R) thread on both ends, sized 1/2″, letting two female-threaded fittings, valves, or appliances be joined directly in line.

It’s made from Rotguss, a corrosion-resistant copper-tin-zinc casting alloy commonly marketed as gunmetal or red brass, with a polygonal wrench flat for tightening, threaded to DIN EN 10226-1. It carries DVGW approval for both gas and drinking water installations.

It’s the smallest common size in the 3280 double-nipple range, used to bridge two threaded fittings on individual fixture connections.
