What are Compression Fittings

Compression Fittings (sometimes also called “Fittings to tighten“) were historically the first solution used for the connection of multilayer pipes and are still widely used in the civil sector because they are reliable and very easy to install. In fact, they do not require specific equipment for assembly: the joints are tightened by hand with a simple plier and all operations are reversible, this means fittings are removable and reusable.

The mechanical coupling of the pipes takes place by screwing the nuts on the fitting, in this way the profiles of the fitting tighten around the pipe, evenly distributing the compression and maintaining an optimal mechanical seal. The O-ring seals inside the fittings, on the other hand, guarantee the hydraulic seal of the system under pressure.

Main advantages

• Simple and reliable principle
• Easy assembly, requires no specific equipment
• All fittings are unscrewable and reusable
• Excellent sealing characteristics under pressure

What are press fittings

Press fittings are a joining system for multilayer pipes suitable for use in hot and cold water distribution systems, for sanitary or heating / cooling purposes. The mechanical coupling between pipe and joint takes place thanks to pressing using manual or electromechanical pliers, which permanently shape the fitting around the pipe in a few seconds. The hydraulic seal between the pipe and the fitting is instead guaranteed by the O-Ring seals inside the fittings. If the pipe is pressed with an electromechanical clamp, the fittings all have a constant and uniform seal, each joint is made in a few seconds and with minimal effort.

Further advantages of this system are safety on site, because all assembly does not require flammable or chemical substances as in other solutions, and the speed of execution: the joints are in fact immediately stable, so as soon as the last joint is made, the system is immediately ready for testing without any waiting time.

The Fornara ForPress series

The ForPress series is compatible with a large number of different profiles (F, TH, U, H, B) and is rich in details that improve performance and facilitate installation.
The fittings are built according to the Leak before press principle: if the fitting has not been pinched then it loses water, this feature allows you to immediately identify any sections that are not pinched during testing with the system pressurized.
The plastic end-of-stroke rings of the tube are also equipped with inspection windows that allow you to see if the tube has been fully inserted and is “in contact” before proceeding with the clamping.

Main advantages of the Fornara ForPress series

• Fittings compatible with different shaping profiles (F, TH, U, H, B)
• Control windows for the stop pipe
• Immediate and uniform sealing of the joints thanks to the use of pliers
• Speed ​​of implementation and immediate testing of the system
• Safety on the construction site
• Low cost of fittings

The complete fittings for each system

In every drinking water distribution system, whether it is a renovation or a new construction, there are specific points where some connecting component is needed that solves a particular situation.

The Fornara line offers a very wide range of fittings that meet the needs of numerous “real” cases such as: switching from one diameter to another, switching from male to female connection, performing eccentric joints etc

All Fornara fittings provide maximum hygienic safety, compliance with Italian and international standards, reliability and long life and a very high quality-price ratio.
