A flare joint is used on gas fittings and uses a nut and flare fitting to make the connection. This is a dry fit with no joint compound. The copper is soft enough that it compresses with the nut and forms the seal.

The number one key to a successful copper pipe sweat joint is achieving proper heat application. This involves using the right torch and flame size to evenly heat the joint without overheating the copper, which can lead to oxidation. Additionally, ensuring that the surfaces of the pipe and fitting are clean and free of oxidation or debris is crucial for a strong bond. Finally, using the appropriate solder and allowing it to flow into the joint properly will ensure a reliable seal.
The same that is used above ground. Sweat fitting coupler. I would not use copper underground in an area that has winter.
You cannot sweat copper pipe if it has water in it. You must remove the water first. Even the steam from water will keep you from successfully sweating a joint without leaks. bob...
Joint compound AKA dope is used as a lubricant and to seal minor imperfections of the threads
Yes they have compression joint fittings for copper.

When you use soft copper tubing, you flare the end to make the connection. You put a nut on the tube and then flare the end so that it looks like a funnel. Then you can connect the tube to a fitting and when you tighten the nut it compresses the copper and makes a seal.

When soft copper tubing is used the end is flared so that it can seal against the fittings. A flaring tool is used to spread the end of the tubing so that it looks like a small funnel. When you tighten the nut onto a fitting it compresses the copper against the flare on the fitting and makes a seal. It is a dry seal, no pipe dope should be used on a flare fitting. This is almost always on a gas line of some sort, air, natural gas, propane or some other gas. It can be used for liquids, but generally isn't.

To effectively seal a copper pipe, you can use a soldering technique. This involves heating the joint where the pipe connects and applying solder to create a watertight seal. Make sure to clean the pipe and fittings thoroughly before soldering to ensure a secure bond.
No, hard copper pipe will split when you try to flare it.
A water-seal pot is required to connect to an HP flare to prevent backflow of gases or liquids from the flare system back into the equipment or process. It acts as a barrier to protect the system from contamination and to ensure proper functioning of the flare.
To fix a leaking PVC joint on a seal, you can try tightening the joint, applying PVC primer and cement, or using a repair coupling.
A flare connection is often preferred to a solder connection in plumbing and HVAC applications because it provides a stronger and more reliable joint that can withstand vibration and thermal expansion. Flare connections create a mechanical seal that is less likely to leak over time, especially in high-pressure systems. Additionally, flare fittings are easier to disassemble and service, making maintenance simpler compared to soldered joints, which are permanent and require heating to remove.
