Crimped fittings interlock, also known as two-piece fittings, are a type of hydraulic fitting that consists of two separate parts that are crimped onto the hose. The two parts of the fitting are interlocked together using a series of threads or a collar, which provides a secure and leak-proof connection between the hose and the hydraulic system. Crimped fittings interlock are commonly used in high-pressure applications, such as in mining, construction, and oil and gas industries. They are available in a range of sizes and configurations, including straight, elbow, and tee shapes, to fit various hydraulic systems. Crimped fittings interlock offer several advantages, including high pressure capacity, resistance to vibration and impact, and improved flow capacity. They are a reliable and cost-effective option for hydraulic systems that require a secure and leak-free connection.
