Airless Paint Spray Hose

Airless paint spray hose is used to convey paint and fluids from airless or pneumatic spray equipment to the sprayer nozzle. Unisource offers four hose options, and four different pressure ratings. Each hose is light in weight and flexible for its type. They provide superior kink resistance. The proprietary tube materials are resistant to most chemicals, paints, and solvents. Unisource offers airless paint spray hose in wireless style for static dissipation. We also offer higher pressure rated styles with wire braid, guaranteeing conductivity. Our highest pressure airless paint spray hose is reinforced with a combination of wire and Aramid braids. This construction achieves extreme high pressure ratings without the weight and stiffness of multi-spiral wire hoses.

Our Series 4710 airless paint spray hose is certified to UL-1450 specifications. Standard hose length is 50-feet with a wire bend restrictor and swivel fitting on both ends. To see information on a variety of thermoplastic hoses from Unisource, check out our Polyflow Thermoplastic Hydraulic Hose section.
