So I had my gas hot water heater vent redone. Had no issues before the work was done. On windy days the pilot light would go out once or twice a day. Loved waking up in the morning to have a cold shower.Found this high wind cap through google search. I replaced my cap within 10 minutes was so easy to install. Have had really windy days and no problems the cap worked perfectly.

This vent cap is perfect for keeping blasts of wind from coming back down the chimney. It was easy to install and works well.

Purchased from seller Express Fireplace & Hobby the 4-inch B-vent Cap, High Wind Cap (aluminum version, as recommended by my HVAC technician to replace the old corroding steel version); $34.04 total for item and shipping. Arrived quickly enough, though I was in no hurry, with minor dents from the item being packed up against the side of the box rather than being surrounded by the packing paper (which could be easily done with normal attention to packing care). The dents are minor and will not affect the performance, so I'm still happy with the purchase from this seller, Express Fireplace & Hobby.The mating tube of this part fit snugly to the OUTER diameter (rather than inside, like the old steel cap) of the vent pipe (pictured). Being thin aluminum, the cap is delicate, and to prevent bending and damage, careful gentle tapping is needed in order to intall it while ensuring it was evenly on axis as it was moved over the pipe until it snapped into the mating groove. Once the retainer tabs are in the groove on the pipe, though secure it became slightly loose. So I tapped it slightly further and may add a screw or three (though not required) in order to prevent any potential rattling noise.Note the labels in the attached pics, such as "WARNING INTERNET BUYERS". I checked the Duravent warranty and, as far as I can tell, caps would still be covered by their five-year limited warranty (considering annual maintenance, cleaning, and inspection by a 'certified technician').

Liked the design. Will have to wait and see if it prevents wind from blowing out pilot light. Wish they would give dimensions on inlet pipe and not just height and width.
