When working with gas fittings, it’s important to use the correct type of tape in order to create a seal that will prevent leaks. For work with either natural gas or propane, you should use tape that has been specially designed to withstand the pressures and temperatures of these gases.
PTFE tape is specifically designed to withstand the pressures and heat that your gas connections might be subjected to all while creating a seal to prevent gas leaks.
It is a flexible, non-stick tape manufactured from a compound called Polytetrafluoroethylene (PTFE) that is often used in plumbing. It is made of Teflon, which makes it resistant to heat and chemicals.
But why should you use PTFE tape on gas fittings? We will give a brief explanation of this below, but you can scroll to the bottom of this article if you’d like more information.
Why Should You Use PTFE Tape on Gas Fittings?
Whether you are working with natural gas or propane, it’s important to use the correct kind of tape in order to seal the fittings. This is done so that they will not leak, which could be dangerous and result in loss of property.
NO 1#: Material Compatibility
PTFE tape is made from materials that are known to be compatible with both natural gas and propane. If you were to use another kind of tape, it might create a seal that would withstand high temperatures for short periods of time but not long-term exposure.
Secondly, it could react chemically with the gas preventing an airtight seal. When there’s a seal, you want it to be airtight so that the gas doesn’t escape.
NO 2#: Flexibility
PTFE tape is highly flexible and will stretch up to 150% of its original size without breaking. This makes it more suitable for use with flared fittings than materials like electrical or masking tapes. It will conform to the inside of your tubing rather than being loose and creating a lumpy mess.
NO 3#: Heat Resistance
Natural gas can get extremely hot, which is why it’s important to use tape that has been designed for high-temperature use. PTFE tape is resistant to temperatures up to 500 degrees Fahrenheit. This makes it ideal for use on gas connections.
NO 4#: Sticky Enough to Stay in Place
PTFE tape is sticky enough to stay in place without causing damage throughout the life of the fitting. When you’re ready to remove the tape, most adhesives can be removed with soap and water. It’s not as likely to create a mess as electrical tape can if you make a mistake.
NO 5#: Prevents Leaks
This tape is thin enough to seal small gaps in connections yet thick enough to create a sturdy bond. It creates an airtight seal that prevents leaks. It’s so reliable that it is the only type of tape to have earned a UL rating from Underwriter Laboratories.
NO 6#: No Residue Left Behind
PTFE tape isn’t going to leave a sticky or hard-to-remove residue behind when you remove it. This makes cleanup easy and won’t make a mess in your workspace the way electrical tape can.
PTFE is also non-flammable and corrosion resistant, so it’s safe for use on gas connections that will be under pressure.
NO 7#: Ease of Use/Installation
PTFE tape is easy to use and install, which makes it perfect for beginners or anyone who isn’t very experienced with plumbing connections. It has a split backing that allows you to easily pull the tape off the roll, so you don’t have to touch it with your bare hands.
NO 8#: Keeps Out Exterior Elements
This tape is designed to keep moisture and other contaminants out of your gas connections. It’s made from a material that can’t be penetrated by water or any other source of corrosion, which means that these elements won’t get inside the connection and damage it over time.
NO 9#: Economical
PTFE tape is very economical when compared to other types of tape. It’s durable enough that you can reuse it or use it on multiple connections without it wearing out, yet inexpensive enough that buying in bulk won’t break the bank.
NO 10#: Versatility
You can use PTFE tape on a wide range of applications, including kitchen fittings like dishwashers and gas appliances. It is generally considered non-conductive, though there are some exceptions to this.
With all of these benefits, it’s easy to see why PTFE tape is so popular among homeowners and plumbers. It’s easy to use yet still offers you complete peace of mind thanks to its high quality and reliability.
Frequently Asked Questions
1. What Kind of Teflon Tape Is Used for Gasoline?
PTFE tape can be used on gasoline connections, but it’s important to make sure that it hasn’t been designed for other types of use. Gasoline is extremely flammable and should only come into contact with products that are resistant to fire.
It’s also important that the product you choose doesn’t contain any elements that will dissolve or weaken in gasoline.
2. When Should You Use PTFE Tape?
PTFE tape is a product that is often used in plumbing. The tape can be used to seal joints on brand new pipework, but it is more commonly used on older pipework. Older pipework may weep more readily when things are moved around.
By using PTFE tape, you can help to prevent leaks and ensure that your plumbing system remains in good working order.
3. Is PTFE Tape the Same as Teflon Tape?
No. PTFE is a type of non-stick, waterproof tape that functions effectively as Teflon tape. It’s less likely to leave behind any sticky residue when you remove it.
Teflon tape can be used on gas fittings, but it has to be the right kind. A non-conductive type should be used on gasoline connections. PTFE is considered non-conductive and is more economical than other types of tape.
It’s also versatile, resistant to damage from elements like water, easy to use, and leaves behind zero residues. So if you’re looking for a product that is reliable and will get the gas fittings job done, PTFE tape is your best bet.
