Pressure means the fitting is designed for copper pipe under pressure. And cup or “C” means it receives a pipe or fitting “Ftg.”

What is a copper pressure fitting?

Copper press fitting is a flameless alternative to soldering copper pipe connections. In this system, a hydraulic tool is used to press specially designed connectors to join traditional pipes. These connectors house a sealing element that, when pressed, creates an even and reliable connection.

What are the different types of copper fittings?





The three most common types of copper pipe used in residential and commercial construction are Type K, Type L, and Type M. A fourth type, used for drain-waste-vent, or DWV, piping, can be found in some older homes.

How does a ProPress fitting work?

Unlike soldering, ProPress fittings do not need a completely cleaned pipe to work. The force of the press creates a strong seal regardless. Unlike soldering, ProPress systems do not need an open flame to be completed. This creates a safer work environment and by not requiring a hot work permit, saves time.

How do you use a copper slip union?

Quote from the video:
Quote from Youtube video: One you actually have to solder in two different pieces and join them together with threads. The other one which I prefer is a Quick Connect.

Is compression fitting better than solder?

Compression fittings are not nearly as robust as soldered fittings making them much more sensitive to powerful stresses. They are not ideal for applications where they could be potentially exposed to lots of flexing, bending and excessive vibration or tube movement.

Can you use compression fittings on hard copper?





Hard copper tubing is typically joined together by soldering fittings onto the ends of the pipe or tube. You can seal joints with hard copper using a mechanical compression fitting. Soft copper can also be soldered, but many people chose to use mechanical flare or compression fittings that seal joints by pressure.

What is difference between type L and Type M copper?

The key difference between types L and M is their pressure rating and wall thickness. The most common copper pipe sizes are ½ and ¾ inches. Type M ½ inch measures 0.028” in wall thickness whereas type L ½ inch measures 0.04” in wall thickness.

Are all copper fittings the same?

You may be surprised to find two types of copper pipe on the home center shelf, Type L and Type M. The difference is the wall thickness of the copper pipe sizes and therefore the pressure it can handle. The exterior dimensions are identical, meaning you use the same copper fittings.

Can you use compression fittings on soft copper?

Quote from the video:
Quote from Youtube video: They use pressure to tighten connections which prevents leakage compression fitting sizes refer to the outer diameter of the pipe. They work with so if you're using a 1/2 inch copper pipe.

What is a slip coupling in copper?



Copper slip couplings are designed without an internal stop and can be slipped over the copper pipe fully. This type of couplings is useful for repairs or situations where using a regular coupling is inconvenient.

What is a slip pipe fitting?

A slip fitting does the job of two couplings and extra pipe. Only one end of the coupling has a stop, allowing the opposite end to slide freely over the end of a pipe. The fittings are then released using a disconnect tool and slide back onto the other end of the pipe for a successful connection and leak repair.

How do I connect copper pipe without soldering?

Quote from the video:
Quote from Youtube video: Looking for an easy way to join solid copper together and you don't like to solder you don't know how to these new push fit fittings are an excellent way to join copper.

Do shark bites ever leak?



SharkBite fittings can leak due to one of these reasons: The pipe was not properly deburred prior to installation. The pipe was not properly inserted. The pipe was not squarely cut.

What is the best way to join copper pipes?

Brazing and press fittings are both reliable and acceptable joining methods for copper pipe. It appears that brazing is preferred for piping 2 inches and above, while press fittings are becoming the norm for piping below 2 inches in diameter.

Do push connect fittings work?

The speed of making a connection with push-fit fittings is perhaps the biggest advantage. In an emergency, you can quickly cap or repair a pipe by simply slipping on a push-fit fitting. Push-fit fittings are a great way to make pipe connections without having to solder or use clamps, unions, or glue.

Do push-fit fittings leak?

When leaks do happen, it’s almost always because of one, or a combination of the following: The pipe isn’t cut properly. The insert isn’t pushed all the way in. The pipe isn’t fully connected to the fitting.

Can you use push fit on copper pipes?



Originally developed to be used with plastic pipe systems, push-fit joints are a good way of joining copper pipes too (although they can’t be used with stainless steel or chrome-plated copper pipe). It’s important that your pipe ends are cut cleanly, so make sure you use a pipe cutter rather than a hacksaw.

What is an advantage of a push to connect coupling?

The ability to make a fast and reliable connection is the most significant benefit of Push to Connect fittings. Whether a new installation or an emergency repair, saving time is saving money. Unlike gluing or soldering, the tubing does not need not be completely dry.

Do professional plumbers use SharkBite?

When and when not to use SharkBite fittings. Most professional plumbers believe that SharkBite fittings and other kinds of push-fit fittings should only be used as an emergency, temporary fix, and not for any enclosed or permanent plumbing system. However, there is a growing selection of DIYers who would disagree.

Can you use push fit for hot water?

Push fit fittings and pipes, like copper, can safely withstand heat and pressure so they’re suitable for water and heating systems.
