What Are Push-to-Connect (PTC) Fittings?
Push-to-connect fittings, also known as quick-connect fittings, allow for easy and fast assembly of air brake lines. Instead of using compression nuts and ferrules, these fittings enable users to simply push the tubing into place for a secure and leak-free connection.
Parker offers D.O.T. push-to-connect fittings in both composite and brass materials, meeting SAE and D.O.T. specifications. This makes them ideal for air brake applications in semi-trucks, trailers, buses, and other mobile equipment.

Advantages of Composite vs. Brass PTC Fittings
When selecting push-to-connect fittings, it’s important to consider the material that best suits your needs. Here’s a comparison:
Composite PTC Fittings
✔ Lightweight & impact-resistant
✔ Can be rotated after assembly for proper alignment
✔ Corrosion-resistant
✔ Ideal for tight spaces
Brass PTC Fittings
✔ High strength & durability
✔ Resistant to extreme temperatures
✔ Suitable for high-pressure applications
✔ Compatible with various environmental conditions
How to Install Push-to-Connect Air Brake Fittings
Installing PTC fittings is a straightforward process. Follow these steps for a secure connection:
- Cut the tubing – Ensure a clean, square cut for the best fit.
- Insert the tubing – Push it firmly into the fitting until it stops.
- Check the connection – Pull back slightly to confirm it’s locked in place.
- Rotate if necessary – Composite fittings allow for rotation after installation.
That’s it! No special tools or extra components are required.
