20/100pcs Pneumatic Fittings Plastic Connector PU 4mm 6mm 8mm 10mm For Air water Hose Tube Push in Straight Gas Quick Connection

Engineer reliable pneumatic and fluid systems with these 20/100pcs plastic push-to-connect fittings. Designed for 4mm, 6mm, 8mm, and 10mm tubing, they provide a secure, leak-resistant seal for air, water, and inert gas lines up to typical working pressures, ensuring consistent system performance. Features and Benefits - Push-to-Connect Design - Enables tool-free, one-handed installation and disconnection for rapid assembly and maintenance without special tools. - Multi-Material Tubing Compatibility - Seals effectively with polyurethane (PU), nylon, and polyethylene tubing for versatile system design. - Four Standard Sizes (4/6/8/10mm) - Covers the most common tubing diameters for pneumatic controls, water lines, and low-pressure fluid transfer. - Durable Plastic Construction - Resists corrosion from moisture and chemicals, ensuring long-term reliability in demanding environments. - O-Ring Seal - Provides a consistent, airtight and watertight connection that minimizes pressure drop and prevents leaks. - Straight Connector Configuration - Maintains a direct flow path to reduce turbulence and maximize efficiency in your pneumatic or fluid circuit. Applications - Pneumatic Control Systems - Connect air cylinders, valves, and tools in factory automation, woodworking, and automotive shops. - Aquariums and Hydroponics - Securely link water pumps, filters, and irrigation lines with reliable, non-corrosive fittings. - DIY and Prototyping - Build custom air or low-pressure fluid circuits for hobby projects, models, and testing rigs. - Compressed Air Lines - Route air to spray guns, airbrushes, and inflators in workshops and garages. Note: Ensure tubing is cut squarely and inserted fully to the shoulder for a proper seal. Check compatibility with your system's maximum pressure and fluid type.
