    Thank God that worked!

I live in a modular home. The hot water heater would blow out every time the wind blew from the south. Years of saying "gotta do something about that" so I did. This worked wonderful. Installed easy and We haven't had an issue even with 60 mph winds. Now to replace the others.

    Good seller, minor packing error could be easily improved
  

*by C***C on Reviewed in the United States on February 1, 2022*

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').
