Features

  • EMPTY TANK: Pre-purged vacuum ready for filling with propane; built from high-grade, welded steel and powder coated for rust prevention
  • OVERFILL PREVENTION DEVICE: Comes with an OPD valve to prevent overfilling; required by law in most States, if your tank doesn't have this, most places won't fill it!

  • SUIT YOUR NEEDS: With a standard-size connection valve, this large 40LB tank will connect as easily as smaller tanks, and work with RVs or trailers, propane tank attachable heaters, and other accessories.

  • Quality brand at a great price
Style: 40 LB Tank
Propane is so much cleaner and quieter than using gas in a generator, but these larger tanks can be hard to find locally. This showed up ready to go and seems to be great quality. Same brand they sell at the ACE Hardware near our house

  • Seemed to be priced within 10% or so of a used one. Go figure??
Style: 40 LB Tank
I did the Facebook/Marketplace and Craigslist ads for a used one. So after a few weeks of looking for a reasonable deal, I gave up. Amazon's price on this (and I bought a smaller one as well) was within 10 or 15% more than some beat-up used hand-me-down. Your experience may vary. :) Anyway, works well, looks good and is 100% as well built as any other tank I've ever owned. ... show more
