Description

Viega Sanpress Inox press tee 28×28 mm x Rp1/2 (model 2317.2, Art. 437190) takes a threaded branch off a stainless steel line. Both run ends are press connections, while the side outlet has a female thread into which a valve, pressure gauge or sensor with a matching male thread screws.

The tee is stainless steel 1.4401. Each press end holds an EPDM sealing element, and thanks to SC-Contur a joint left unpressed by mistake leaks during filling. The fitting has spanner flats, so you can hold the tee with a spanner while a part is screwed into the branch.

It takes Viega 28 mm system pipe in drinking-water, heating and compressed-air lines. The system is designed for 16 bar, and Viega gives maximum operating temperatures of 80 °C in drinking water and 105 °C in heating. The tee is DVGW and VdS approved, with VdS applying only in combination with 1.4521 pipe. A press tool and jaw do not come with it. For a removable connection, see the union connector and the press fittings category.

Which thread standard is it (G, R or Rp), and how is the joint sealed?

The branch has an Rp1/2 female thread, which is a parallel pipe thread. A part with a tapered R male thread screws into it and the seal is made on the thread itself, so apply a thread-sealing material suitable for the line. This joint does not need a flat gasket.

Which pipes is this fitting compatible with?

Pipe is pressed into the two run ends only: they take Viega stainless steel system pipe with a 28 mm outside diameter, grade 1.4401 or 1.4521. The Rp1/2 outlet is not meant for pipe; a threaded part is fixed in it. In a sprinkler installation that needs VdS approval, use pipe in grade 1.4521.

What maximum pressure and temperature does it withstand in drinking-water and heating systems?

The Sanpress Inox system is built by Viega for PN 16 nominal pressure, which equals 16 bar. In drinking-water installations the operating temperature limit is 80 °C (95 °C is allowed for no more than 60 minutes), and in heating systems to DIN EN 12828 it is 105 °C.
