Pneumatic fittings provide the essential link between tubes, hoses and other components in a pneumatic system. Air fittings feature tighter seals and have lower pressure requirements than hydraulic fittings and are typically offered in various connector types.  In addition to connecting pneumatic components and stopping the flow of unused ports, miniature fittings are also used to control air flow pressure and directional flow.

Choosing the Right Fittings for Your Pneumatic System

Fittings help control the force and directional flow of compressed gas or air used in pneumatic systems. One of the first considerations in choosing a connector is the type of vessel that you will be connecting to such as the flexibility of the hose or tube, as well as the inner diameter (ID) and outer diameter (OD) of the vessel to ensure an adequate seal and secure connection. Fitting material choice for your pneumatic connector is also important, including gas compatibility or resistance to heat or corrosion.
Other considerations in choosing the right pneumatic system connector include:
  • Type of connection and the function it performs
  • Operational pressure of the pneumatic system
  • Operating temperature range
  • P.S.I. requirements for your application
  • Amount of vibration produced by the pneumatic system
  • Thread type of the receiving fitting

Miniature Air Fittings provide Versatility for Your Pneumatic System Applications

Although simple in design, miniature pneumatic fittings have been an important part of Pneumadyne’s product offering for over 30 years. A variety of configurations, sizes and materials are available to link the pneumatic components in your application.

Most of these fittings are also electroless nickel plated for corrosion resistance.

Threaded Air Fittings

A variety of configurations including Adapters, Bulkheads, Couplings, Elbows, Tees and Plugs are offered with thread sizes ranging from 10-32 UNF to ½ NPT. Our popular captured o-ring seal is standard on fittings with 10-32 & ¼-28 UNF threads and provides a superior seal ensuring a leak resistant pneumatic system fitting.

Barb to Barb Air Fittings

Pneumadyne’s barbed fittings are offered in Coupling, Cross, Elbow and Tee configurations and available for use with polyurethane tubing ranging from 1/16 ID to 3/8 ID. To meet installation preferences, both single and double barb designs are featured. These precision machined brass fittings are electroless nickel plated for corrosion resistance.

Push-to-Connect Air Fittings

Push-to-Connect fittings enable quick tubing connection and disconnection. A variety of Male and Female ConnectorsElbows and Tees feature tube ODs ranging from 1/8 to 3/8 and 10-32, 1/8 NPT or ¼ NPT threads. To ensure a leakproof fit, thread sealant is standard on all male pipe threads and the 10-32 UNF thread features an o-ring for a superior seal.

Metric Air Fittings

Several of Pneumadyne’s fittings are also available with M3, M5 and M6 threads. Configurations with M5 and M6 threads feature our captured o-ring for a superior seal and leak resistant fit. Nylon gaskets are included with M3 threaded fittings.

Stainless Steel Air Fittings

Stainless Steel fittings are suitable for applications in corrosive environments where brass and Acetal are typically prohibited. Our 316L Stainless push-to-connect fittings feature FPM seals to withstand high temperatures. Barbed configurations are machined from 303 Stainless Steel and passivated for corrosion resistance.
