What is PU pipe connector manifold type?

Pneumatic push-in fittings, also called pu pipe connector, provide a leak-free means of easily connecting hoses in your compressed air system. Fittings can have between 1-6 inlet/outlet ports or may have additional functionality such as an integrated pressure gauge or silencer.

How to install pneumatic pus-in PU pipe connector?

The hose is easy to install by pushing it into the release ring-end of the fitting until it stops. The internal lock claws will automatically clamp around the hose for an immediate and secure connection.

How to uninstall pneumatic push-in PU pipe connector?

Push the release ring inward towards the fitting to disengage the lock claws. Similarly pull back on the tubing to remove it. The opposite end may be another push to connect fitting, threaded male, threaded female or a threaded male with an inner hex-type connection. The threaded connections usually have a pre-applied thread lock coating. The tube must be fuller inserted for a proper seal.

The pros and cons of using push-in fittings

Pros

• Push-in fittings come with a quick release system which allows for simple and easy installation by hand. Thereby, eliminating the need for tools and adhesive. Due to the ease of connecting and disconnecting air lines, it allows for frequent changing of air lines at a low cost.
• Push-in fittings are offered in a wide range of tube sizes, connections, and thread combinations to suit the desired outcome.

Cons

• Push-in fittings require firmer tubing with harder walls to resist being damaged by the internal claws. Firm tubing will be less flexible; therefore, it may not be suitable for systems where hoses will be routed around tight turns. If flexible tubing is desired, we recommend using hose tail barbed fittings instead of push-in fittings. Nylon, Polyethylene (PE), or Polyurethane (PU) tubing material is ideal for push-in fittings. It is also best suited for pneumatic (air) applications; however, it can be used for water applications.

Applications

Push-in fittings are used in all types of compressed air systems, but are most commonly used in applications having pneumatic cylinders, tools, and equipment. They can be used for water applications, but extra measures have to be taken (controlled surge pressure, water compatibility, insert ring, etc.) The push on connection method allows for rapid changing of components, so it is ideal if you have one air source for multiple tools that can be exchanged out.
