Poly Tube Compression Fittings

A Wide Range of Poly Tube Air Fittings Available for Pneumatic Tubing Systems

Poly tube compression fittings connect and secure plastic air tubing in pneumatic systems, allowing proper flow between components by linking pneumatic or compressed air lines to the system. Without requiring additional tools, these connectors grip and seal plastic tubing for a quick, reusable solution. Pushing the poly tube straight into the fitting, an internal collet with teeth will grip the outside of the tube to prevent removal, and an O-ring will seal around the tube to reduce leakage. They are easily removed by pushing the collet inward while pulling the tube out.

At Coilhose Pneumatics, we offer an extensive inventory of high-quality fittings, with a variety of air tool tubing connectors to support compressed-air and pneumatic tubing systems, including:

• Male and Female Connectors
• Elbows and Branch Trees
• Ferrules
• Threaded Tube Ends

Made from brass, our industrial air line compression connectors offer increased corrosion resistance when compared to zinc-plated steel, but are softer and more susceptible to wear. They are available in 1/4”, 3/8”, and 1/2” OD sizes, offering a reliable connection point for flexible polyurethane and PA-12 nylon tube fitting applications.

Applications of Industrial Air Line Compression Connectors

Poly tube air fittings can be used across various markets, including packaging and printing, pneumatic, chemical, and industrial. They require no flaring, soldering, or other tube preparation prior to installation, delivering a secure and reliable connection between pneumatic or compressed air systems and their application lines. Our poly tube compression fittings are designed to support the efficient operation of:

• Air lines
• Lubrication lines
• Fluid transfer
• Chemical dispensing
• Cooling lines
• Machine tools
