Viega Bronze Elbow 90° 1", Art. 264048

A thread is cut either inside a part (female) or on its outer surface (male). This 1" elbow has one of each: the R 1 male end goes into a 1" female outlet, for example on a valve or tee, and the Rp 1 female end takes a pipe or nipple with a 1" male thread.

Both ends follow EN 10226-1. The Rp 1 end is a parallel female thread and the R 1 end a tapered male thread, and each seals in the thread itself, whereas a G joint is usually sealed by a gasket. For sealing, Viega names three options: hemp with paste, PTFE thread tape or thread-sealing cord.

Yes. Viega's instructions name heating water and gases, along with drinking water, as media for these threaded connectors, and Art. 264048 is listed on DVGW certificate DV-7401AO2957. Viega approves them for gas installations subject to the notes on each model, so read the notes for model 3092 before using it on gas.
