Viega Bronze Extension Fitting 1", 40 mm, Female x Male Thread, Art. 357207

Viega extension fitting 1″ (model 3525, Art. 357207) moves the connection point of a one-inch tap or valve 40 mm forward. Its tapered R 1 male thread is screwed into the outlet in place, and the parallel Rp 1 female thread on the front end carries the tap, the valve or a further fitting.

This tap extension is made of bronze and is turned by an internal polygon with a 22 mm spanner size. Viega states an overall length of 60 mm, and the R thread arrives knurled from the factory, so hemp can go on without roughening.

The fitting is meant for drinking-water, heating and gas installations. Art. 357207 is named on DVGW certificate DV-7401AO2957, which concerns products for gas and water supply, and on DV-7421CS0446 for Viega tap extensions. Sealing material and tools are not included.
