  • Press-fit installation saves labour time

ProPress 90° elbow 1/2″ press × 1/2″ FNPT

This bronze crimp elbow joins 1/2 in copper tube to a 1/2 in female NPT thread in a single press operation. It is designed for potable-water systems and meets ASTM B75 and ASTM B88 standards. The fitting suits installers who want a flame-free joint on copper piping.

Bronze body with EPDM seal rated 200 psi at 250 °F

The bronze construction and EPDM O-ring handle the listed pressure and temperature limits without solder or flux. The press-to-FNPT configuration lets you transition directly to threaded valves or equipment. No bolt holes or flange thickness apply to this elbow shape.

Replaces soldered 90° copper elbows

The press connection cuts installation time and removes open-flame risk on renovation sites. The jump is worth it when local code accepts press fittings and the system stays within the 200 psi and 250 °F ratings. Buyers needing larger diameters or different thread types should select another fitting.

Questions about this item

What maximum pressure and temperature does the ProPress 90° elbow rated for?

The bronze elbow with EPDM seal is rated for 200 psi maximum operating pressure and 250 °F maximum operating temperature, meeting ASTM B75 and ASTM B88 requirements for potable-water systems.

What tube and thread sizes must the pipe and mating fitting match for this elbow?

Side A accepts 1/2 in copper tube for press-fit connection, while Side B provides 1/2 in FNPT threads for a female pipe-thread adapter.

Which tool and jaw are required to press this fitting, and what common step is missed?

Use a Viega ProPress tool with the correct 1/2 in jaw; the step often missed is fully inserting the tube until it bottoms out before pressing, otherwise the seal can leak.
