Copper Press-Fit Cap

The Viega ProPress 2956 is a copper crimp fitting cap designed for potable water systems. It fits 1-1/2 inch copper tube size using a press-fit connection method. The fitting carries certifications including CRN, CSA, FM, IAPMO UPC, ICC, NFPA 13D, NFPA 13R, NSF/ANSI 372, NSF/ANSI 61, PHCC and UL Listed. It suits plumbers and contractors needing a permanent end-of-line seal.

Build Quality and Daily Use

The cap body is copper with an EPDM O-ring rated from 0 to 250 degrees Fahrenheit at up to 200 psi. Overall length measures 1 5/8 inches and there is no centre stop. Press-fit installation eliminates open flame on site, reducing fire risk and speeding up joint completion. The copper construction resists corrosion in typical potable water conditions.

Before Ordering Check

Verify the existing pipe is 1-1/2 inch copper tube size and that your press tool accepts this fitting profile. Confirm local code accepts the listed standards for the intended application. Buyers needing a threaded or soldered cap, or a fitting with an integrated centre stop, will need a different product. The cap is not sold with any pipe or press tool.

Questions about this item

What pressure does the ProPress press-fit connection handle?

The press-fit joint is rated for a maximum operating pressure of 200 psi, which is the limit the copper cap and its EPDM O-ring seal are designed to hold.

What copper tube size and overall length does the 2956 cap require?

It fits 1-1/2 inch copper tube and has an overall length of 1 5/8 in, so the pipe must be cut to leave that much clearance for the cap to seat fully.

How is the ProPress 2956 cap installed and what step is often missed?

Cut the copper tube square, deburr, mark the insertion depth, then press with a calibrated ProPress jaw; the step people skip is verifying the depth mark is still visible after pressing.
