Gasket
Joint compound AKA dope is used as a lubricant and to seal minor imperfections of the threads
Not cleaning the pipe or joint enough, not using flux, or not heating the pipe or joint enough. You use the blue tip of the flame on the joint and the capillary action sucks the solder into the joint. You have to clean the pipe with sandpaper or steel wool, the joints with a fitting brush on the inside, and use a proper flux and solder.
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.
It is the only type of weld you can make to seal this type of joint. There are flange ends that can be welded onto pipe with a butt weld, but sockets and slip-ons must be fillet welded.
it is defined as the pipe cemented in the well to seal off formation fluids and to keep the hole from caving in.
Pipe joint compound or Teflon tape
HDPE pipe can use a rubber ring, if the rubber ring is properly sealed with a steel gasket. The rubber ring must be placed in a groove in the pipe and then the steel gasket is placed on top of it.
To effectively seal a leaking pipe joint, you can use plumber's tape or pipe sealant. First, turn off the water supply to the pipe. Then, clean the area around the joint to remove any dirt or debris. Apply the plumber's tape or pipe sealant to the threads of the joint and tighten it securely with a wrench. Turn the water supply back on and check for any leaks. If the leak persists, you may need to replace the joint or seek professional help.
Pipe grooved at end of pipe with grooving machine. Butt grooved pipe or fitting together and slip rubber seal onto end of each grooved joint, apply light coating of grease made for grooved piping on rubber seal. Coat split coupling for joint with grease also and put coupling around joint and clamp together tightly.
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.
Mission CAP or IPS plug if there is a female fitting

The pipe under the sink is leaking at the connection because there may be a loose or damaged seal or fitting, causing water to escape from the joint.
Pipe grooved at end of pipe with grooving machine. Butt grooved pipe or fitting together and slip rubber seal onto end of each grooved joint, apply light coating of grease made for grooved piping on rubber seal. Coat split coupling for joint with grease also and put coupling around joint and clamp together tightly.
You can use pipe thread sealant aka "Pipe Dope" you can get this at most hardware stores.
A hole has developed in the spout or where it screws onto the pipe needs more Teflon tape or joint compound to seal the threads.
If you have a PVC pipe leaking at the joint, you should first turn off the water supply to prevent further leakage. Then, dry the area around the leak and apply PVC primer and cement to seal the joint. Allow it to dry completely before turning the water supply back on. If the leak persists, you may need to replace the joint or seek professional help.
