Teflon Tape and Pipe Dope On Gas Piping? 

I was trained to use just pipe dope on gas and oil. Install drip leg at fixture

@theolumbersplunger I put them before the flex line. Here in Idaho, we use the UPC, Section 1212.8 states the trap is to be installed downstream of the appliance shut off valve as close to the inlet of the appliance as practical, before the flex connector

My boss only uses tape or dope one or the other, but I'll use both tape and dope every time so I sleep better. 👍 And we put the sediment trap on the appliance side.

Just dope. On the gas control valve too

One or the other. Gas company uses a yellow Teflon tape, specifically for gas lines.

NYC, special Teflon Tape for gas, which is yellow. Pipe dope on master plumbers test is 'Pro Dope' only, nothing else.

Dope only...sediment trap as close as possible to control valve...😉

in france we dont know this blue glue. We only use yellow teflon (special gaz product).

I'm from Albuquerque NM and here code says it has to be at the gas valve on the wall but we can use both so I always use both tape and dope

I don’t put the dope on the nipple going into the valve only tape but use tape on the rest of the sediment trap. Also i do the sediment trap onto the valve this is here in California.

As an HVAC technician. I only use pipe dope for gas lines. I also add the drip leg right by the tank if applicable. Sometimes I'll put it a little further up stream if the drop comes down, then flex lines to the WH.

I put the sediment trap as close to the point of use as possible.

A protective device should always be located as close as possible to the protected device unless there is some issue of user safety, emergency access, or vulnerability to some sort of environmental threat.

Use 2 wrenches, look at that Gas Valve pivot forward

So here in Fresno CA we put it on gas control valve, or right after shut off valve. Sometimes they don’t even seem to care still pass inspection 😂

Central Valley , CA and we use yellow teflon with pipe dough

Western WA. Today I just used white dope. Usually I'm a yellow tape blue dope guy. But that's what the propane co did on a commercial stove set up that I followed up on with a shut off and some other code details.The fire suppression guy was there and I was in a hurry. So ,whatevs ,as the kids would say. I hope it flies.

So I looked it up. Here in germany you can use teflon tape and loctite and I could be wrong with this but I guess hemp with fermit is used by the majority of plumbers here for gas

I use both and always have sediment trap near appliance

I put both, the only thing I do different is that I put the Teflon second that's how the plumber that I started with made me do it.

Tape (with dope) keeps the threads clean for the next plumber.

Wall and dissimilar metals get both. Same material threads only needs 1 of the 2.

I live in N.Y and the old pipe fitter’s that I worked with would say you don’t use tape near the gas valve because you don’t want a small piece of tape to extinguish the flame and fill the house with gas (This was before thermal couplers ) it made sense now .gas units lights on demand, but there was a time when people lived, and died by the fact that that the pilot light was kept on. Today equipment is much safer than it ever was. It’s just made of old crushed up Chevrolet and rusted Fords and plastic.. but much safer…

I do both. Gas tape and pipe dope and i always install my drip leg by the gas valve.

I put the sediment trap at the unit because it makes more sense. The sediment flows into the trap and it gets replaced when i put in a new water heater. I also use tape and dope because that's how the company I work for likes it, but if it were me, I would just use rector seal.

I usually put the sediment trap on the water heater and I usually always put Teflon and pipe dope. Just in case 👍

I use both and sediment trap at the appliance

Tape and dope. Sediment trap at the gas control valve 🍻

All I've ever used is teflon tape. All I've ever seen any contractor I've hired use is teflon tape.

A tech came to replace a regulator underneath my cooktop and only used white teflon tape. I asked him why not yellow teflon or pipe dope and he said it’s unnecessary. And the only difference between the white and yellow teflon is it’s thickness.. but I thought the yellow teflon is specifically formulated to not react with natural gas..What do you guys think? I have no idea on the subject

I only use tephlon and pipe dope on high pressure systems or anything above 1 inch and drip legs at fixture

I usually put the sediment trap at the control valve if there is no room to put it at the gas valve.

I basically always use both tape then dope and put the trap at the unit like you’ve done here

Pipe dope only but have used both and at the gas valve for drip

That's a lot of dope... Replacing that gas valve soon.

Dope and Teflon sediment filter at tank

yes and yes

So I’m from Florida and we have individual gas companies as well as some plumbing companies that do gas. What’s that situation like in Texas? Majority one way or the other?

Just pipe dope and for tank heaters I put it on the tank but for tankless I put it right after the ball valve.

Yellow tape yellow dope

Just pipe dope. Sometimes the Teflon can get loose and clog up your lines.

CA it goes just after the valve and tape and dope all day.

Code in my area is does it work, yup don’t move it no more

What kind of wrench is the silver auto auto adjustment jaw

Don't use tape on gas valve or oil pumps it can split the housing and can get stuck in the seat

Tape is risky by gas valves it can hold open the valve if it gets past the screen. But I’ve seen it done

Teflon tape only 4 me unless i have a leaky fitting.

We are not allowed to use Teflon on gas pipe in Delaware

Pipe dope only and sediment trap at the gad shut off

Tape only.

Drip leg at fixture and just dope but white or yellow never blue dope

So pipe to manifold connection is not where you want to use pipe tape not even a little bit! But I guess you'll find out!

I put both

Same as you ny

Just pipe dough....dirt leg at tank connect.
