Metal Push in Fittings

Pneumax Metal Push-In Fittings are high-performance connectors manufactured from brass or stainless steel for use in pneumatic, low-pressure hydraulic, and vacuum applications. These fittings provide reliable, tool-free connections for nylon and polyurethane tubing in industrial automation systems.

Features and Specifications

• Material: Made from nickel-plated brass or stainless steel, with versions specifically designed for welding environments and high corrosion resistance.

• Tube Sizes: Accommodate metric tubes ranging from 4mm to 16mm outside diameter.

• Thread Sizes: Available with thread connections M5, M6, M12x1.5, 1/8", 1/4", 3/8", and 1/2" for integration with a wide variety of system components.

• Operating Pressure: Typically rated up to 10 bar for air and up to 250 bar for high-pressure brass series; breaking pressures can reach 40–168 bar depending on tube size and fitting series.

• Temperature Range: Standard metal fittings operate from -20°C to +80°C, with special series (e.g., stainless steel, HP) rated up to +140°C.

• Seal: Equipped with O-rings (NBR or Viton) and locking mechanisms to ensure leak-free performance and secure tube retention under pressure.

• Fluid Compatibility: Suitable for compressed air, vacuum, and certain hydraulic fluids; high-pressure series can handle oils and greases in lubrication systems.

Application and Benefits

• Used in industrial automation, automotive manufacturing, robotics, packaging machines, and environments requiring robust, reliable pneumatic connections.

• Metal push-in fittings offer high mechanical strength, resistance to aggressive chemicals, and long service life, making them ideal for harsh or high-duty-cycle applications.

• Designed to integrate seamlessly with Pneumax technopolymer and metal tube ranges, including PA12 nylon and polyurethane options.
