PU coil hose, also known as a polyurethane coil hose, is a type of flexible tubing used for pneumatic applications. It is made from polyurethane, a durable and lightweight material that resists abrasion, tearing, and kinking. PU coil hoses are designed to be highly flexible and expandable, allowing them to stretch and retract without losing their shape or functionality. They are often used in applications where a compact and lightweight hose is needed, such as in automotive repair, industrial manufacturing, or pneumatic tools. PU coil hoses are available in a range of sizes, colors, and lengths, and can be fitted with a variety of end connectors, such as quick-disconnect fittings, swivel fittings, or barbed fittings, to suit different applications and tools. They are known for their high durability, resistance to kinking, and ease of use.
