Steelman Automotive Air Hose is coiled and measures 25' long, with 1/4" x 1/4" NPT rigid reusable fittings on both ends. The hose is made of polyurethane tubing, which is 25% lighter than rubber and highly kink-resistant to withstand twisting or crushing. This easy-to-handle hose also offers excellent abrasion resistance, six to ten times better than rubber or nylon.
