The L-type sleeve is a robust solution designed for crimping hydraulic fittings on high-pressure hoses type Z, ensuring secure and durable connections in demanding industrial applications. Suitable for rubber and plastic hoses with textile reinforcement, as well as suction and pressure hoses with reinforcing spirals, it guarantees reliability even under extreme operating conditions. To achieve optimal performance, the sleeve must be carefully matched to the hose’s internal diameter (Dw) and external diameter (Dz), while its length (L) should not exceed the tail length of the fitting (Lk). With precise dimensions—external diameter D1, internal diameter D2, and locking diameter D3—the sleeve provides a perfect fit and consistent sealing. Manufactured from high-quality carbon steel and finished with galvanization, it offers excellent resistance to corrosion and mechanical wear, extending the service life of the entire hydraulic system. This makes it an ideal choice for industries where safety, durability, and efficiency are top priorities.
