Questions about this item

Will the 3/4 in press-fit end join my existing copper pipe without soldering?

The press-fit connection is designed for 3/4 in pipe and uses an EPDM O-ring to seal without soldering, while the opposite end provides a 1/2 in MNPT thread.

How can I confirm the joint is leak-free after pressing?

Press the fitting with a compatible tool, then pressurise the system up to the 200 psi rating and inspect the 2 21/32 in straight adapter for any moisture at the O-ring seal.

Does the box include the press tool or pipe?

The package contains only the 316 stainless steel straight adapter; press tools and pipe must be sourced separately.
