Description for Taco 418-4

You already know Taco Hy-Vents as the industry standard for dependable, long-life service. The high-capacity, float-style vent can be placed either on the boiler or at the high points throughout the system. With threaded connections--1/8", 1/4", 1/2" and 3/4" --and operating pressure ratings up to 250 psi, these brass-body, nickel-plated vents meet the system requirements of even your largest installations. Vents are easily serviceable, if needed, by simply unscrewing the vent cap. Taco Hy-Vents are available in a variety of styles including the Slim-Line Hy-Vent and High Pressure Hy-Vent.

Worked for my needs

Comments about 1/2" FNPT x 3/4" MNPT Hy-Vent:

I ordered this to replace the air vent on my weil mclain gold plus 40 indirect fired water heater (powered by gas boiler).
This was the only product that I could find to match the Taco vent that was already there (and leaking). I still needed an adapter down to 3/4" FNPT, and plenty of teflon tape, but the vent is holding nicely.
My first vent from supplyhouse was delivered broken, but RMA was quick turnaround, and sent me a good one.

Good for a main boiler vent

By MM on LI

from Melville NY

Verified Buyer

Comments about 1/2" FNPT x 3/4" MNPT Hy-Vent:

This is the large size Taco vent, not to be mistaken for the smaller vents used on baseboard. This is much larger and threads into a 3/4" female or 1/2" male adaptor. I used this for a main air vent on my feed manifold on a boiler. Vents a high volume of air, is quick to install and requires no adjustment other than twisting the cap one turn from closed. Solid construction, this is not thin sheet metal, its a heavy cast body. I would use this for venting any large section of pipe or as a main vent on a boiler. For baseboard or radiators, use the smaller 1/8" version.
