TUUBER 2-inch Vent 2X Superior Seal Air Admittance Valve

TUUBER 2-inch Vent 2X Superior Seal Air Admittance Valve

Q: can pipe dope be used or Teflon fkr threads?

Can be used but not recommended and not needed. This is just a vent to allow water to drain.

Q: Can this be used outdoor?

[I'm not a plumber.] But, I don't see why it couldn't be used outside. The seals might be more prone to wear if exposed to the weather.

Q: What is the dfu rating?

From their website: “174020 - 2" Dual-Seal 20 AAV maximum DFU rating Individual and Branch 10 DFU, Stack 12 DFU”

Q: can you just screw it on or is teflon tape required to seal the pipe threads?

a little tape never hurts but not necessary.
