Plastic Body Push To Connect Fitting

Pneuforce Plastic Body Push-to-Connect Fittings for Pneumatic Tubing

Pneuforce plastic body push-to-connect fittings are designed for fast, reliable connection of polyurethane, nylon and other pneumatic tubing used in compressed air automation systems. Manufactured with a durable POM engineering polymer body and nickel-plated brass threaded connections, these fittings provide a strong, lightweight and dependable solution for pneumatic valves, cylinders, manifolds, air preparation units and machine automation equipment.

Pneuforce fittings are known for their distinctive Click-Click feel and sound during tube insertion and release. This positive tactile feedback helps confirm proper tube engagement and disconnection, giving maintenance technicians and machine builders confidence when assembling or servicing pneumatic circuits.

What Are Push-to-Connect Pneumatic Fittings?

Push-to-connect fittings, also known as push-in fittings or one-touch fittings, allow pneumatic tubing to be inserted directly into the fitting without compression nuts or special tools. The internal gripping mechanism holds the tube securely, while the internal seal helps prevent compressed air leakage.

To disconnect the tubing, the release collar is pressed and the tube can be removed. Pneuforce fittings are designed so tubing can be connected and reconnected repeatedly without damaging the tube or fitting when installed correctly.

The Pneuforce Click-Click Connection

Unlike many competing push-to-connect fittings that provide little or no feedback during tube removal, Pneuforce fittings are engineered to produce the distinctive Click-Click feel and sound when the stainless steel gripping mechanism releases.

This positive tactile and audible feedback helps maintenance technicians know the tube grip has released, making tube removal clearer, more controlled and more confidence-inspiring during machine assembly, service and troubleshooting.

POM Body with Nickel-Plated Brass Threads

The POM engineering polymer body provides a durable, lightweight and precise fitting housing suitable for general industrial pneumatic applications. The nickel-plated brass threaded section provides strength, corrosion resistance and reliable connection to pneumatic components.

This combination gives Pneuforce plastic body fittings an excellent balance of performance, durability, weight and cost effectiveness.

Thread Sealing Options

Pneuforce plastic body fittings are available with multiple thread styles for different pneumatic components and international machine standards. NPT and BSPT tapered threads include pre-coated thread sealant for faster, more consistent assembly.

Universal Tri Thread fittings and parallel thread models such as M3, M5, M6 and 10-32 UNF use an NBR O-ring seal to provide reliable sealing against the component port.

Common Applications

• Pneumatic Cylinders: Tube connections for single and double acting cylinders.
• Control Valves: Connections for solenoid valves, manual valves and valve manifolds.
• Air Preparation Units: Filters, regulators, lubricators and FRL assemblies.
• Vacuum Venturi: Pneumatic tubing connections for vacuum generators and ejectors.
• Packaging Machinery: Fast assembly and maintenance of compressed air circuits.
• Industrial Automation: Robotics, conveyors, actuators and OEM machine systems.

Choosing the Correct Push-to-Connect Fitting

Choose the fitting based on tube outside diameter, thread type, fitting shape, working pressure, temperature range and available installation space. Always match the tube size exactly to the fitting size and ensure the tubing is cut square before insertion.

For harsh environments or high-temperature applications, Pneuforce also offers all-metal nickel-plated brass push-to-connect fittings.
