Viega ProPress 2956 Copper Cap

The Viega ProPress 2956 is a copper press-fit cap designed for 2 inch copper tube. It terminates potable water lines without soldering, using an EPDM O-ring for a secure seal. The fitting meets CRN, CSA, FM, IAPMO, ICC, NFPA 13D, NFPA 13R, NSF/ANSI 372, NSF/ANSI 61, PHCC and UL standards.

Suitable for press-tool installers

This cap suits plumbers using Viega press tools who need a permanent, flameless end stop on 2 inch copper. It is not for technicians without press equipment, for systems exceeding 200 psi or 250 degrees F, or for non-copper pipe materials requiring different fittings.

2 inch copper termination

The cap handles potable water up to 200 psi and 250 degrees F with an overall length of 1 13/16 in. It runs out for high-pressure steam, extreme cold below 0 degrees F, or applications demanding a removable threaded closure instead of a permanent press connection.

Questions about this item

What copper tube size must I already have for the ProPress 2956 cap to press onto it?

The cap is made for 2 in copper tube size and uses a press-fit connection with an EPDM O-ring, so the existing tube must match that diameter.

Will the 2956 cap hold pressure on a system that still uses older copper piping rated below 200 psi?

The fitting is rated for 200 psi maximum operating pressure and meets NSF/ANSI 61 and 372, so it will perform to its rating if the older piping and joints also meet that pressure class.

How can I confirm the 2956 cap is sealed correctly after pressing it onto the tube?

After pressing, visually inspect the press indicator ring and the EPDM O-ring seat, then pressure-test the line up to 200 psi at temperatures between 0 and 250 °F to verify a leak-free joint.
