This 3-foot propane regulator hose with the built-in tank gauge is seriously convenient - no more guessing how much propane you have left! It's a universal low-pressure regulator that works with most gas grills, heaters, and fire pit tables. The connection is 3/8 inch female flare nut with 5/8-18UNF threads - which is the standard Type 1 connection for most propane appliances. The hose itself is 5/16 inch diameter and made from high-quality rubber that's thick, flexible, and corrosion-resistant. Installation couldn't be easier - it's tool-less, so you just hand-tighten the connections to your tank and appliance. The gauge is my favorite part - it gives you a clear reading of how much propane is in your tank, so you're never surprised by running out in the middle of cooking. The flow capacity is 95,000 BTU per hour, which is plenty for most grills and fire features. I've used this with my fire pit table and it creates a secure, air-tight connection with no gas leaks whatsoever. The construction feels solid - the swivel nut makes connecting to the tank easy without kinking the hose. A little note - it's normal to hear some noise from the regulator when gas is flowing; that's just resonance and nothing to worry about. The 3-foot length gives you some flexibility in tank placement without being so long that it gets in the way. I've had mine through a full season of use now, and it's held up great against weather and UV exposure. If you're tired of the guesswork with propane tanks or need to replace an old, worn-out regulator, this is definitely worth getting. The peace of mind knowing exactly how much fuel you have is worth it alone!
