Description
Viega plug 1″ with an external rim (model 3290, Art. 320294) closes a female-threaded outlet that is not needed, such as the spare branch of a tee. The brass plug screws in with its R 1 male thread and is tightened with a spanner on its square head.
The R 1 thread is a tapered male thread to EN 10226-1. Viega knurls its R male threads at the factory, so hemp can be wound on without roughening them first. Sealing material is not included. Viega’s range also has a 1″ plug without the external rim, model 3291.
The plug is intended for drinking-water, heating and gas installations. Tees, nipples and other parts for screwed lines are in our range of fittings for threaded pipework, while the maker’s press systems are among the Viega products we carry. Before the installation goes into service, Viega requires a load and leak test.
