Pneumatic push-in fittings, also called push to connect fittings, 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 push-in fittings
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 fittings
Push the release ring inward towards the fitting to disengage the lock claws and 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, 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.
FAQs – Pneumatic Push-in Bulkhead Connector for PU Pipe:
1. How does a pneumatic push-in bulkhead connector help in connecting PU pipes through panels or enclosures?
A pneumatic push-in bulkhead connector allows PU pipes to pass securely through panels or walls while maintaining an airtight connection, ensuring stable and reliable airflow.
2. Is the push-in bulkhead connector suitable for high-pressure pneumatic applications?
Yes, the push-in bulkhead connector is designed to handle standard pneumatic pressures, providing strong locking and leak-free performance in industrial air systems.
3. Can the bulkhead connector be used with different sizes of PU pipes?
Absolutely. The bulkhead connector is available in multiple size options, making it compatible with various PU pipe diameters used in pneumatic setups.
4. Does the push-in bulkhead connector allow easy installation without special tools?
Yes, the push-in design of the bulkhead connector enables quick installation—simply push the PU pipe into the fitting and secure the threaded section on the panel.
Great finishing and tight sealing on both sides. The connector works smoothly even under high pressure. Definitely worth the price.
We used this Bulkhead connector for multiple pneumatic lines and the results were excellent. Completely leak-free and very durable.
High-quality connector with excellent grip on PU tubing. No pressure loss at all. Very reliable fitting for machines running continuously.
Solid build and perfect threading. Keeps the PU pipe fixed firmly even during heavy machine vibration. Highly recommended.
Super easy to install and very long-lasting. Airflow is stable and no loosening over time. One of the best connectors we have used.
