Brass Push-In Tube Fittings — Fast, Reliable Connections for Industrial Applications

At Industrial Parts Fittings, we understand that performance, durability, and ease of installation matter in demanding industrial environments. That’s why we offer a comprehensive range of brass push-in tube fittings — precision engineered fittings that deliver secure, leak-resistant connections without the need for tools or complicated assembly.

Why Choose Brass Push-In Tube Fittings?

Brass push-in tube fittings are a type of quick-connect or push-to-connect fitting that lets you join tubing simply by pushing it into the fitting — no threading, soldering, or clamps required. These fittings feature internal grip rings and O-ring seals that lock and seal the tube instantly, speeding up installation while maintaining a reliable connection.

Key advantages include:

  • Fast, tool-free installation — push the tube in until it seats for an instant connection.
  • Re-usable and serviceable — fittings can be disconnected and reused if needed.
  • Durable brass construction — excellent corrosion resistance and strength for industrial and fluid handling systems.
  • Versatile compatibility with common tubing materials such as nylon, polyurethane, and polyethylene (tube type depends on product spec).

Whether you’re building compressed air systems, fluid distribution lines, or automation tubing runs, our push-in fittings save time while delivering professional performance.
