Viega 79305 – Frequently Asked Questions
1) What are the two ends on the Viega 79305 ProPress adapter?
The 79305 is a P x FPT adapter: one end is a 1/2 inch ProPress crimp socket for copper tube, the other is a 3/4 inch female pipe thread. So it takes you from 1/2 inch press copper to a 3/4 inch male-threaded connection such as a valve nipple, appliance connector, or threaded riser.
2) Is the 1/2 inch side of the Viega 79305 the press end or the threaded end?
Press side is 1/2 inch, thread side is 3/4 inch. Viega sizes P x FPT adapters press-end first, and the connection type is listed as P x FPT with dimensions of 1/2 inch x 3/4 inch. If you need the reverse (3/4 inch press to 1/2 inch FPT), the 79305 is the wrong part number.
3) Is the Viega 79305 the right fitting to tie 1/2 inch copper into a threaded shutoff or gauge port?
Yes, if that device has a 3/4 inch male thread. The adapter gives a 3/4 inch female pipe thread on one side and a 1/2 inch press socket on the other, so it is the transition piece between press copper and any 3/4 inch MPT component: hose bibb nipple, pressure gauge tee, backflow assembly port, or a threaded brass valve.
4) Can I use the Viega 79305 bronze ProPress adapter on potable drinking water lines?
It is a Zero Lead bronze fitting, which is what Viega designates for potable water service. The body material is bronze throughout, so it pairs with copper tube systems on domestic hot and cold water without a dissimilar-metal concern at the press joint.
5) What does Smart Connect on this Viega adapter actually do for the installer?
Smart Connect is Viega's unpressed-joint feature: an unpressed fitting deliberately leaks during pressure test so you can find the joint you missed before the walls close up. On the 79305 it applies to the 1/2 inch ProPress end only. The 3/4 inch FPT side is a conventional threaded joint and still needs thread sealant or tape.
6) Do I need a special press tool jaw for the Viega 79305?
The press end is 1/2 inch, so you press it with a 1/2 inch ProPress jaw in a compatible press tool. No soldering, no flux, no open flame, which is why these get specified for occupied buildings and tenant turnovers where hot work permits are a problem.
