The Wolverine Flex Air Line Hose - 36 Inch long. A replacement hose for use with your regulator and Wolverine engine system. A great air hose that's reinforced for durable airsoft use. Same hose that's included with the Storm Regulator package. Fully braided and includes QD connections for a secure and perfect fit on your gun and regulator. Works on most systems.The line itself is 36 inches long, but with the connectors, it's exactly 38.5 inches in length. The braiding and connection ends are very high strength and really well built. One of the best flex lines we've ever seen for HPA airsoft rigs.
