Viega 25316 – Frequently Asked Questions
1) Is the Viega 25316 MegaPressG tee rated for gas lines?
MegaPressG is Viega's press system for gas, and the 25316 is a carbon steel MegaPressG tee. It presses onto black iron pipe rather than being threaded, so a gas branch can be made without cutting threads or open flame. Confirm the fuel gas and pressure against the approvals for your jurisdiction before you press.
2) What pipe size does the Viega 25316 tee fit on all three outlets?
All three ends are 1-1/4 inch, so it's a straight equal tee: 1-1/4 x 1-1/4 x 1-1/4. The connection pattern is press on every port (P1 x P2 x P3), meaning there is no threaded run or branch, every outlet gets pressed onto 1-1/4 inch pipe.
3) Can I use a MegaPressG tee on an existing threaded black iron gas line?
Yes, and that's the usual reason to reach for one. Because all three ports are press (P1 x P2 x P3), you cut the existing 1-1/4 inch pipe, deburr, mark insertion depth, and press, no threading or welding. The tee itself is carbon steel to match black iron pipe. You will still need threaded adapters wherever you transition to valves or appliance connections.
4) Is a carbon steel MegaPress fitting OK for a potable water line, or do I need copper or stainless?
Carbon steel is the material here, which is what you want for black iron pipe service such as fuel gas, compressed air, and similar industrial runs. It is not a potable water fitting, for domestic water you want Viega's copper ProPress or stainless press fittings instead. Match the fitting material to the pipe material you are pressing onto.
5) What does Smart Connect technology do on the Viega 25316 tee?
Smart Connect is the feature designed into the sealing element so an unpressed connection leaks noticeably during pressure testing. That lets you find a missed joint on a gas branch before the system goes into service rather than after. It is built into the 25316 tee itself, no separate part to order.
6) How much clearance do I need to install a 1-1/4 inch MegaPressG tee in a tight chase?
The fitting body measures 6.457 inches by 4.303 inches by 2.205 inches, so plan the pocket around that plus room for the press tool jaw to swing around each port. In a joist bay or chase, the jaw clearance is almost always the limiting factor, not the tee. Weight is 1.644 lbs, light enough that it does not need temporary support while pressing.
7) What is the exact part number and origin for the Viega 1-1/4 inch MegaPressG tee?
Order it as Viega part 25316. It is made in Germany. The description on the carton reads MegaPressG tee, carbon steel, 1-1/4 inch by 1-1/4 inch by 1-1/4 inch, which is useful if you are matching a submittal or a counter order.
