Push-to-Connect Pneumatic Fittings | 4-10mm OD Tube | Quick-Connect Air & Water Hose Couplings

PM Air Couplings are push-to-connect fittings designed for reliable, leak-free connections in pneumatic and low-pressure water systems. These straight couplings accept 4, 6, 8, and 10mm OD copper or plastic tubing, enabling fast installation without tools for a secure, professional-grade seal. Features and Benefits - Push-to-Connect Design - Enables rapid, tool-free installation and disconnection, saving significant time on assembly and maintenance tasks. - Multi-Size Compatibility - Accommodates 4mm, 6mm, 8mm, and 10mm outer diameter tubing, providing versatile solutions for various system layouts. - Brass Construction with O-Ring Seal - Ensures durability, corrosion resistance, and a consistent, leak-proof connection for both air and water applications. - Straight Connector Configuration - Ideal for creating in-line extensions or repairs within your tubing runs without altering direction. - Ergonomic Colored Collar - Allows for easy, single-handed operation by simply pushing the collar to insert or release the tube. Applications - Pneumatic Tool Systems - Connect air lines to tools, valves, and cylinders in workshops, automotive, and manufacturing environments. - Low-Pressure Water Lines - Suitable for drip irrigation, water filtration setups, and coolant line connections where quick changes are needed. - Compressed Air Networks - Build or repair air supply lines for spray guns, dust collection, and automated machinery with reliable fittings. - DIY and Prototyping Projects - Perfect for hobbyists and engineers creating custom pneumatic or hydraulic circuits requiring fast reconfiguration. Note Ensure tubing is cut squarely and deburred before insertion for optimal seal performance and to prevent O-ring damage.
