  • 120 Gallom Propane Tank
Style: ASME Certified
Tank was received from the shipper I damaged with the exception of slight marks in the paint coating. Fine all other respects. Tank appears well built to ASME specs. Good value for price paid.

  • More is Better
Style: ASME Certified
When Edison decides to cut power because of the wind, be prepared with darn near 100 gallons of propane to run your RV Generator. It took more time, patience and parts to get my Generator to run off this Bulk tank. The Propane Company added a 1st stage regulator to protect underground piping, I had to add an Independent 2nd stage and set to an 11” water column then I had to Tee in below my onboard RV Regulator setup. It runs like a Champ now. ... show more

  • Flame King (Propane Tank) refuses to stand behind this SUBSTANDARD PRODUCT.
Style: ASME Certified
Where to start? They are selling decades old tanks - which they just sand down and paint and try to pass off as new. This is the condition of this tank after just a few months. Not only is it totally corroded - but leaking gas to the point I had to have an emergency service call to remove it and put it way away from my house for safety. THEN they refused to refund even though they are LYING about this product and want to send me another tank - suggesting that I put a cover over it or use Rustoleum on it. DO NOT BUY FROM THESE PEOPLE!!! ... show more

  • good experience
Style: ASME Certified
pretty neat I can order a 120 gal propane tank and have it delivered to my house. The delivery guys where great and put the tank on the other side of the house where I built a pad with a hand truck. Price was much better than the local tank suppliers at least 300-400 dollars. I had purchased a gas fireplace so the gas line was run from tank (15 ) feet to fireplace, then propane delivered. Propane delivery guy needed to check things out since first delivery so he put some propane in tank and checked for leaks on tank and in house. No leaks, everything good and filled tank.

  • Good value
Style: ASME Certified
Had it filled today by the gas company and had no issues. The tank delivery service was great! They placed it exactly where I wanted it, so it was an easy installation. Good size for the number of appliances I have and one of the best prices I found. Much cheaper than the local gas companies. The only negative I've found is the paint. It doesn't peel, but it's actually rusting through in areas. I'll just have to get some quality oil based exterior white and paint over it. If you decide to paint yours, just make sure you use a color that's acceptable. White is one in our area and silver is another. It needs to reflect heat and not absorb it like darker colors do. ... show more
