Introduction
At HERED Pneumatic, we pride ourselves on our expertise in pneumatic components, with a special focus on push-in fittings. This guide offers an in-depth look at these essential components, their applications, and why HERED is your ideal partner for pneumatic solutions.
Understanding Push-In Fittings
Push-in fittings, also known as push-to-connect or one-touch fittings, are revolutionary components in pneumatic systems. They allow for quick, secure connections between tubing and pneumatic devices without the need for tools, significantly reducing installation time and complexity.
How Push-In Fittings Work
1. Internal Structure:
- Sealing Ring: Typically made of NBR (Nitrile Butadiene Rubber), it surrounds and seals the air tubing.
- Lock Claw: Usually stainless steel (SUS316), it grips the tubing firmly to prevent disconnection.
- Release Mechanism: Often a POM (Polyoxymethylene) button or sleeve for easy disconnection.
2. Connection Process:
- Simply insert the tubing into the fitting until it stops.
- The lock claw automatically grips the tubing, creating a secure seal.
3. Disconnection:
- Press the release button or sleeve.
- While holding the release, gently pull the tubing out.
Key Features of HERED Push-In Fittings

Installation Best Practices
1. Proper Tubing Preparation:
- Use a specialized tube cutter for clean, square cuts
- Avoid using scissors or utility knives, which can create uneven edges
2. Insertion Technique:
- Insert the tubing firmly until it reaches the internal stop
- Gently pull back to ensure proper engagement of the lock claw
