Quick-Connect Fitting304 Stainless Steel Pneumatic Threaded Straight Air Pump Hose Quick Connector High Temperature Resistant

• Quick Connection: Plug and unplug manually, shortening the installation, commissioning and maintenance time.
• Reliable Sealing: Equipped with O-ring and pre-coated PTFE anti-leakage glue, reducing the risk of leakage.
• Corrosion-Resistant Adaptability: Made of 304/316 stainless steel, it can withstand weak acid/alkali, humidity and high temperature, suitable for harsh environments such as food, chemical and marine industries.
• Flexible Piping: Can rotate 360°, adapting to narrow spaces and complex pipeline layouts.
• System Protection: Closes the passage during plugging and unplugging, reducing medium leakage and pressure loss.

Key Parameters

• Pipe Connection: 4 mm (PC4 series)
• Thread Specification: M5, R1/8 (01), R1/4 (02), R3/8 (03), R1/2 (04)
• Pressure Rating: ≤1.6 MPa (depending on the hose)
• Temperature Range: -40～250 ℃ (depending on the sealing ring material)
• Applicable Medium: Compressed air, water, oil and some corrosive fluids

Typical Applications

• Pneumatic Automation: Quick connection between cylinders, solenoid valves, FRL units and air pipes.
• Clean/Food Industry: Avoids contamination and is easy to disassemble and clean.
• Chemical/Marine Industry: Corrosion-resistant, extending service life.
• Mobile Equipment: Enables quick disassembly and assembly for convenient transportation.

Selection and Installation Points

• Selection: Match the port according to the outer diameter of the air pipe (4 mm) and thread specification (e.g., PC4-01).
• Installation: Ensure the pipe orifice is vertical and undamaged; insert it to the bottom and pull back to confirm firm connection; press the release ring to pull out when disassembling.
• Maintenance: Regularly inspect the sealing ring and clamping jaws, and avoid excessive bending of the air pipe.
