Bronze Press-Fit Adapter 1 in x 3/4 in

This Viega ProPress 2912ZL bronze adapter joins a 1 in press-fit copper tube to a 3/4 in female NPT thread. It is designed for potable water systems and meets ASTM B75 and ASTM B88 standards. The straight adapter shape provides a direct transition between press and threaded connections. Installers use it to connect press piping to threaded valves or equipment.

Verify Pipe Size Thread Type And Pressure Rating

Confirm the existing copper tube is exactly 1 in copper tube size for the press end. Ensure the mating component has a 3/4 in male NPT thread for the female threaded end. Check that system pressure does not exceed 200 psi and temperature stays within 250 Degrees F. The EPDM O-ring is compatible with potable water applications.

EPDM O-Ring Enables Press Connection Without

The factory-installed EPDM O-ring creates a watertight seal when pressed with a compatible ProPress tool. This eliminates the need for solder, flux or open flame on the press side. The bronze body resists dezincification in potable water. The 1 27/32 in overall length fits tight spaces where a union would be too long.

Questions about this item

Does the box include the press tool and copper pipe, or do I need to buy them separately?

The box contains only the bronze adapter with its factory-fitted EPDM O-ring; the press tool and 1 in copper tube for Side A must be purchased separately.

Should I choose the 1 in x 3/4 in model or a different size for a 3/4 in female-threaded line?

This 2912ZL adapter matches a 1 in press-fit copper tube on Side A to a 3/4 in FNPT thread on Side B, so select it when that exact transition is required.

What does the 200 psi rating mean once the fitting is pressed onto the tube?

After a correct press, the joint is rated for 200 psi maximum operating pressure and 250 Degrees F maximum temperature in potable-water systems.
