Stainless Steel Fittings

Stainless Steel Fittings

Pneumax stainless steel fittings are engineered for demanding pneumatic, vacuum, and low-pressure hydraulic applications, offering superior corrosion resistance and mechanical strength. They are available in a wide selection of push-in, threaded, and adaptor styles crafted from AISI 316L stainless steel or RX-series brass with stainless steel components.

Features and Technical Specifications

  • Materials: Constructed from AISI 316L stainless steel (push-in Series SS) or RX-series brass with stainless steel elements for specific adaptors and flow control uses.

  • Tube Compatibility: Designed for metric tube sizes (commonly 4mm–12mm OD), supporting polyurethane, PA12 nylon, and other industrial tubing.

  • Thread Types: BSPP (parallel), BSPT (tapered), and NPT from M5 through 1/2", with adaptors and reducers available for custom circuits.

  • Pressure Rating: Standard stainless steel fittings handle compressed air or vacuum up to 10 bar; specialized high-pressure series can support much higher pressures as required in hydraulic or lubrication systems.

  • Temperature Range: Typical operating range -20°C to +140°C, providing reliable sealing and function in aggressive chemical or washdown environments.

  • Seal Options: Fitted with O-rings (NBR, Viton, or FKM depending on application) for reliable leak-free operation.

Common Series and Configurations

  • SS Series: Includes straight adaptor, male/female, elbow, bulkhead, tee, banjo, and flow control models—with parallel or tapered threads for pipes and panels.

  • RX Series: Brass body with stainless steel components—designed for food, beverage, and high-corrosion industrial installations.

  • Quick-Fit Options: Stainless steel quick push-in solutions for automation, actuator blocks, and modular manifolds.

Benefits and Applications

  • Ideal for harsh environments including chemical processing, food & beverage, robotics, and outdoor installations where corrosion or contamination must be minimized.

  • Long-term durability, high mechanical retention, and resistance to vibration and thermal cycling.

  • Available in a wide range of sizes and configurations to suit complex pneumatic panel layouts, air supply lines, and actuation islands
