Description

Viega Sanpress Inox press elbow 45°, 28 mm (model 2326, Art. 435806) connects two 28 mm stainless steel pipes and turns the run through 45°. It has a press connection on both sides, so the two pipe lengths are pressed directly into it.

Both press ends hold a factory-fitted black EPDM sealing element, which a cylindrical pipe guide protects as the pipe is inserted; the body is stainless steel 1.4401. With SC-Contur, a connection that was never pressed is not tight: it leaks visibly when the line is filled.

According to Viega, in a drinking-water, heating or compressed-air line the elbow withstands up to 16 bar, with up to 80 °C in drinking water and up to 105 °C in heating. DVGW approval covers the system, and Viega’s VdS certificate, valid only with 1.4521 pipe, also lists this article. Where one side must plug straight into another fitting, the alternative is the same-size elbow with a plug-in end. Only the elbow is supplied, without press tool or jaw; other fittings are under press fittings.

What does SC-Contur mean, and how does it help during pressure testing?

SC-Contur is Viega's name for a design feature of its press connectors, not a standard. Until a joint has been pressed it cannot seal, so an end you forgot to press is revealed by leakage during the leak test. Viega confirms the effect for a water test between 1 and 6.5 bar and an air test between 22 mbar and 3 bar; on this 28 mm elbow it works at both press ends.

Which pipes is this fitting compatible with?

Each press end is sized for 28 mm Viega system pipe made of stainless steel 1.4401 or 1.4521. Push each pipe in as far as the insertion depth you marked beforehand, and only then press. The pipe is not supplied with the elbow.

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

For Sanpress Inox, Viega gives 16 bar as the operating pressure, with temperature limits of 80 °C for drinking water and 105 °C for heating water. In drinking-water installations Viega allows brief peaks of up to 95 °C, for no longer than 60 minutes. These limits extend to this 28 mm elbow as part of the system.
