Specially designed tubing feeds air and fluid through spray guns. Depending on the application, hoses are available in many different materials, diameters, and lengths. A hose set includes an air hose and a fluid hose to cover both lines in a spray gun. Other factors to consider include the maximum working pressure level, attachment methods, and environmental conditions. Using the wrong tubing can result in excess pressure drop and inefficient spraying.
Three-piece reusable hoses feature connectors on both ends. Threaded for compatibility with standard guns and cups, adapters are available to achieve other desired fittings. Reinforced EPDM tubing is durable and resistant to oil. Nylon tubing is highly flexible and often features a synthetic rubber cover for external protection. High-tensile synthetic braid is ideal for maximum coupling retention and flexibility under pressure. Reusable connectors are cost effective when using bulk hoses or tubing.
