The Viega 79300 is a bronze straight adapter designed for potable water systems. It connects a 1/2 in press-fit copper tube to a 1/2 in FNPT threaded pipe. The fitting uses an EPDM O-ring and meets ASTM B75 and ASTM B88 standards for reliable performance.

Verify Press Tool and Copper Tube Compatibility

Before ordering, confirm that your press tool is approved for this fitting profile and that the copper tube matches the 1/2 in CTS dimension. The adapter is rated for a maximum operating pressure of 200 psi and a maximum temperature of 250 Degrees F. Ensure system conditions stay within these limits.

Questions about this item

Does the 79300 adapter come with the EPDM O-ring installed or must it be purchased separately?

The fitting ships with an EPDM O-ring already seated in the press-fit end, so no separate seal is required.

When should I select the 1/2 in press-to-FNPT straight adapter versus another configuration?

Choose this 79300 model when joining a 1/2 in copper tube to a 1/2 in female NPT thread in a straight run.

What does the 200 psi rating mean for a potable-water installation?

It certifies the bronze body and press joint for continuous service up to 200 psi at temperatures up to 250 Degrees F.
