VIEGA Rotguss Double Nipple 3/4″ Male x Male Thread, Gunmetal (Brass Alloy), Art. 266615

Description

The VIEGA Rotguss double nipple (model 3280, article 266615) is a short, straight connector with an external (R) thread on both ends, sized 3/4″, 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 a standard way to bridge two threaded fittings — such as a valve and a coupling — without needing a length of pipe between them.
