Is Propress a mechanical joint?

1.1 Summary Stainless steel pipe and fitting system using cold press connection technology. The system is assembled when the pipe is fully inserted into the fitting, then pressed on both sides of the fitting seal, creating a mechanical joint.

What is press fit piping system?

The Pressfit piping system is an innovative, rigid, self-restrained mechanical joining method for schedule 5 or lighter weight lightweight stainless steel and carbon steel pipe. This proprietary mechanical pipe joint is designed for use in small-bore piping systems, NPS ¹⁄₂ (DN15) to NPS 2 (DN50).

How does a Propress work?

Unpressed connection with the Smart Connect feature allows liquids and/or air to pass by the sealing element during pressure test. Pressed connection is pressed in front of, on top of, and behind the seal making a gas- and water-tight seal. The Smart Connect feature is sealed during pressing.

What is a mechanical fitting in plumbing?

Mechanical fittings They attach to the end of a pipe segment via circumferential grooves pressed (or cut) around the end of the pipe to be joined. They are widely used on larger steel pipes, and can also be used with other materials.

How much space do you need between ProPress fittings?

Tubing Diameter Minimum Distance (inches) Minimum Distance (mm)
2 in 3/4 in 20 mm
2-1/2 in 5/8 in 15 mm
3 in 5/8 in 15 mm
4 in 5/8 in 15 mm

What is meant by press fit?

An interference fit, also known as a press fit or friction fit is a form of fastening between two tight fitting mating parts that produces a joint which is held together by friction after the parts are pushed together.

What is a press fit coupling?

Learn More About Press 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.

Why is ProPress so expensive?

They are expensive because they are electro-hydrolic. If you can’t stomach the price of the Ridgid or Rothenberger get a manual Nibco. That, and the tons of value it adds to any plumber from all the money he can make off it.

How do I connect two different size pipes?

Bushing Fittings – Bushings, sometimes called reducer bushings, are used for connecting two pipes of different sizes. The larger diameter of the bushing fits inside of the larger pipe. The smaller pipe is then inserted into the smaller end of the bushing.

What are the different sizes of plumbing pipes?

In most cases, the main pipeline from the street to your home is either 3/4 or 1 inch in diameter, supply branches use 3/4-inch-diameter pipe, and pipes for individual components are 1/2 inch.

Why are ProPress tools so expensive?

How does a press fit fitting system work?

The term “press-fit” refers to a joining method for tube systems by means of fit- tings, which are mechanically pressed with specific tools. The pressing operation leads to a mechanical joint between the tube and the fitting. Hydraulic tightness is achieved by the O-ring-system.

Can a press fitting be used to weld pipe?

With press fittings, connections can be made in a fraction of the time that it takes to weld or solder pipe. Plus, significantly less training is required to operate the press tool compared to welding, brazing or soldering. This makes press fittings an excellent labor saving solution, especially when installing large-scale pipe systems.

Why are press fittings used instead of soldering?

Until recent years, tradespeople traditionally relied on welding, brazing and soldering to complete connections. While this is still a commonly used method for installing pipe systems, press fittings offer a variety of benefits that make them a better choice over welding or soldering in some instances.
