The Freeman 1/4 in. x 50 ft. Polymer Hybrid Air Hose with NPT Fittings has a working temperature range of -58 degrees F to 250 degrees F, allowing you to work at colder sub-zero temperatures versus comparative models. This pneumatic air hose features 1/4 in. NPT brass fittings with swivel plugs and universal coupler, which resists rust while allowing the hose to twist in any direction without decreasing air flow. The hybrid PU material construction provides excellent cold weather flexibility and makes the hose kink resistant. Bend restrictors prevent the air hose from kinking at the ends and increase its life. The non-marring finish of this lightweight and durable air hose is great for indoor finish work to avoid damage. The air hose is an ideal air compressor accessory for DIY home improvement and repair projects as well as professional construction jobs, and is covered by Freeman's 1 Year Professional Tool Warranty.
