Push to Connect Fittings

Designed for easy installation and straightforward use, push-to-connect fittings—also known as push-in or push fittings—are versatile components applicable to most pneumatic systems. Push-to-connect fittings are well-suited to sections requiring frequent disconnection and reconnection. They feature ends constructed to accept tubing when the fitting is pushed into the tube.

Polyconn has the push-to-connect fittings you need and the service you deserve. Explore our extensive catalogs and price lists for more complete specification information before placing your order. If you don’t see the exact push-to-connect fitting required by your application, let us know as we specialize in sourcing hard-to-find parts to meet the demands of any pneumatic system.

Composite Push-to-Connect Fittings

Composite push-to-connect fittings are an ideal solution for most industrial, robotics, machinery, mobile, or instrumentation applications. Polyconn has a full range of custom-designed and ready-to-ship composite push-to-connect fittings. Features include:
  • Collet detents fully retracting gripper teeth
  • Working pressures up to 150 PSI
  • 28” Hg (99% Vacuum)

D.O.T. Composite Push-to-Connect Fittings

Designed and manufactured to meet all requirements set by the Department of Transportation (D.O.T.), our D.O.T. composite push fittings are easy to assemble, resist mechanical pull-out during operation, and are specifically designed to be assembled and disassembled multiple times.

Inch Composite Push-In Fittings

Most USA-based companies and pneumatic systems use imperial measurements.  Polyconn offers a vast range of inch composite push-to-connect fittings as all components in an assembly must follow the same measurements. The bodies of these push fittings are constructed from PBT, and the threaded sections utilize nickel-plated brass.

Metric Composite Push Fittings

Metric composite push fittings are designed for installation into any metric pneumatic system. They feature bodies constructed from PBT with NBR seals, operate in a temperature range from 32° to 140°F, and are a lighter-weight, more economical option than their brass counterparts.

Transition Composite Push-to-Connect Fittings

Not all systems follow consistent measurements. Transition composite push fittings are your best option when you need to connect an inch tube to a metric thread or vice versa. While universal threads are not stocked, we offer options with BSPT, BSPP, or NPT threading.

Metal Push-to-Connect Fittings

Metal push-to-connect fittings are reliable and durable components for any system constructed from nickel-plated brass with metal tube. While capabilities, pressure restrictions, and other features will vary depending on your selected material and fitting model, all Polyconn’s metal push-to-connect fittings deliver high-quality performances and long operational lifespans.

D.O.T. Brass Push-to-Connect Fittings

D.O.T. brass push fittings are an ideal solution for systems that do not operate at temperatures over 200°F. They meet all guidelines and specifications set by the D.O.T. and SAE. They are often used in air brakes, tire inflation, and other pneumatic applications.

Nickel-Plated Brass Push Fittings

Polyconn’s nickel-plated brass push-to-connect fittings utilize electroless nickel plating to increase chemical resistance in your components. These high-quality and durable options are often found in robotics, conveyor systems, and other pneumatic applications requiring the transfer of compressed air and some liquids.

Stainless Steel Push-to-Connect Fittings

Stainless steel push-in fittings are a good choice for pneumatic systems where acetal, brass, or nickel-plated brass cannot be used. Our inventory is constructed from forged or machined bar stock 316 stainless steel and specifically designed to ensure superior clamping with many tube types.

Metric Stainless Steel Push-In Fittings

Similar to our standard stainless steel push fittings, metric stainless steel push-to-connect fittings are durable options that add aesthetic appeal to any metric pneumatic system. They are manufactured from forged or machined bar stock 316 stainless steel to provide long-lasting, reliable connections.
