This kink-resistant professional hose by Member's Mark was designed using a Sure-Flow System. This system features an inner rib which provides kink-resistance to ensure continous water flow. It also makes the hose more flexible and easier to handle.The radial-braid reinforcement provides a high burst strength, and the abrasion-resistant outer layer is tough enough for construction jobsites and other hazard-heavy areas. The hose is equipped with a spring protective collar that prevents kinking at the faucet. The industrial-grade couplings are crush proof and leak proof for a tight connection.
