Questions about this item

What comes in the box with the Viega ProPress 2956 cap, and do I need to buy the EPDM O-ring separately?

The cap ships with its EPDM O-ring already installed; no separate seal purchase is required.

How do I know the 1/2 in copper ProPress cap is the right version for my potable-water line?

It is rated for 200 psi at up to 250 °F and carries NSF/ANSI 61 and 372 certifications for drinking water.

What does the 200 psi pressure rating mean when the fitting is pressed onto 1/2 in copper tube?

The joint will hold 200 psi continuously from 0 °F to 250 °F once the press tool completes the crimp.
