Questions about this item

Will the 2 in press-fit end connect to my existing 2 in copper tube sized for ASTM B88?

Yes. Side A is a 2 in press-fit fitting made to ASTM B88 copper tube size, and the bronze body with EPDM O-ring seals up to 200 psi at 250 °F.

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

Pressurise the system to its working pressure — up to 200 psi — and inspect the 3 1/8 in straight adapter for any weeping at the press-fit and MNPT connections.

Does the 79285 come with the press tool jaws or pipe dope for the 1 1/2 in MNPT threads?

The box contains only the bronze straight adapter with its factory-fitted EPDM O-ring; press jaws and thread sealant are purchased separately.
