Function and benefit: The rotary connection on the pressure washer can rotate 360 degrees to reduce load on the rod, hoses, and operators. This design prevents hose twisting and kinking, improving durability and ease of use. Performance specs: Max working pressure 4000 psi; max flow rate 30.0 GPM. Suitable for hot and cold water with long service life. Temperature and material: Maximum working temperature 120 C (250 F). Made from stainless steel for corrosion resistance and reliability. Dimensions and threads: Outer diameter of the external thread is 0.66 inches; inner diameter of the internal thread is 0.59 inches. Connects via 3/8 NPT external swivel joint and 3/8 inch female thread connection, with a universal swivel that can connect to compatible fittings. Compatibility and connection options: Designed to work with standard 3/8 NPT external swivel fittings and 3/8 inch female thread connections. The universal swivel enables connection to a wide range of compatible hoses and accessories. Use scenarios: Fleet vehicle washing and maintenance bays: Enables continuous cleaning without hose torque buildup, reducing operator fatigue and hose wear. Construction and industrial exterior cleaning: Allows flexible movement around buildings, equipment, and stairs while maintaining steady water flow. Agricultural and farm equipment cleaning: Supports long, maneuverable cleaning sessions with hot or cold water while protecting hoses and fittings. Why it stands out: Combines a 360degree rotating swivel with durable stainless steel construction, clear thread specifications, and broad compatibility to minimize hose kinker and kinking, extend hose life, and improve operator comfort during pressure cleaning tasks.
