30'' x 3/4'' High Capacity Gas Flex Line - Premium Quality Black Non-Whistle Fire Pit, Fireplace, Dryer Gas Line - Perfect Gas Line for NG or LP Fire Pits - Versatile Usage - Easy Installation

I built my own gas fire pit . Other gas flex brands would whistle as the gas would flow through the flex. This flex is whisper quiet. No whistle or unwanted gas flow sounds. Gas flow is consistent.

After 3 different returns, this one was perfect for my Chambers Model C stove. No signs of leaks, seems very solid, just wish they had a longer line available.

Very nice gas flex line for my gas fireplace log set. No whistling or noise whatsoever. Be careful about the fittings that come with this set to make sure they fit your gas pipe and burner. I had to purchase additional fittings to make the connections (two trips to the hardware store). But then, the fireplace worked great--much improved.

Used it on my Generac Home Generator where the generator meets the 3/4" black gas line. Very durable and great flexibility.

Got an fire pit installed, i told the contractor it whistles really loud when you turn the gas up. He added some valve to make it "more silent" but there was little to no height in the flame... So i said what about a whistle free flex line... he told me "oh no its not that its just that pressure is too high"........ IDIOT! I bought this, installed it myself, MAGIC the obnoxious whistle is gone and i got a HUGE flame! IDIOT CONTRACTOR!

The media could not be loaded. My firepit installation was amazing!!! The noise.. not so much. I didn't even consider the whistling effect of the hose. After installing this hose... 99% of the whistle is gone. There is only a slight "whoosh" sound when the gas valve is fully open. You really can't even hear it over the flame. What an upgrade!!!! If you have a whistle going on, don't hesitate, get this!!

For hook up to generator off NG

HAD to fix the whistle in our new firepit usage. It was driving us crazy not being able to enjoy the flames and company with the noise always a deterrent. It was an easy fix once the works were undone and this replacement hose was installed. There is only a super tiny bit of noise at the very highest degree of gas volume but overall this was a blessing to find and I wish the original installers of our backyard haven would have known/recommended it's usage vs. us trying to solve a problem after building was complete. Would highly recommend this line for a peaceful solution to anyone who has experienced this whistling noise while using their gas firepit.
