What is a Push-to-Connect Fitting?
Push-to-connect fittings (also known as push-in or quick-connect fittings) are reusable connectors that quickly attach tubing for compressed air, pneumatic, or fluid systems. Designed for ease of use, they form a tight, leak-free connection with a simple push.
How Do Push-to-Connect Fittings Work?
When tubing is inserted, the collet’s stainless-steel teeth grip the tube, while the O-ring forms an airtight seal. Pressing the release ring disengages the collet, allowing the tube to be easily removed.
Where Are Push-to-Connect Fittings Used?
Commonly used in automation, pneumatic control systems, HVAC, packaging lines, and industrial machinery, making them ideal for installations that require quick disconnection and system flexibility.
Are Push-to-Connect Fittings Reusable?
Yes, they can be reused multiple times without degrading the seal, making them excellent for prototyping, testing, and maintenance applications.
