The Acme A770A25B is a 1/4" 1 Rigid, 1 Swivel Flexcoil Polyurethane Coiled Air Hose. The hose eliminates the two most common limitations of other self-storing air hoses – kinking and abrasion. The lightweight, yet extremely durable hose will withstand the rigors of tough industrial environments while maintaining its resiliency over a long period of time. Swivel fitting is provided with thread seal, eliminating the need for sealing tape or paste.
