was a replacement for my autovent on NTI boiler. was a little larger in diameter than the original, yet fit the case opening. Works great. Fair retail price.

Solid air vent
This air vent does a great job on initial system fill. Allowing air out of the system at a very fast rate which allows a quicker system fill time. I like that the cap is suppose to be tight for normal operation which takes out the guess work. I have two in my system: one which came with my indirect water heater (triangle tube SMART) and I put one on my low loss header (hydraulic separator) for the viessmann boiler I just installed. Also is priced about $10 cheaper than others which is a plus (means I can have a spare on the shelf without spending big bucks).
