Is the BEL 45Â° metric tube end, type ZMR311, light series, carbon steel compatible with standard crimping sleeves for hydraulic hoses?

Yes. The BEL 45Â° metric tube end, type ZMR311, light series, carbon steel is designed for crimping in hydraulic and industrial hoses and is compatible with standard crimping sleeves selected for the specific hose type. It features a metric tube connection with BEL (cutting ring) sealing and a regular hydraulic âtailâ (type Z), and the product description explicitly states it is intended to be crimped using a crimping sleeve suitable for the hose. Ensure you use a sleeve matching the hose inner diameter, reinforcement type and crimping specification (profile, pressure rating) recommended by the hose manufacturer and follow proper crimping procedures and tooling for safe, leak-free assemblies.

Does the BEL 45Â° metric tube end, type ZMR311, light series, carbon steel require a specific crimping sleeve profile?

BEL 45Â° metric tube end, type ZMR311, light series, carbon steel does not require a unique proprietary crimping sleeve profile. It is designed for crimping in hydraulic and industrial hoses using a crimping sleeve appropriate for the specific hose type and size. Use a sleeve compatible with the hose construction and diameter, and follow the hose and sleeve manufacturerâs crimp dimensions and tooling settings to ensure a correct, leak-free crimp.

Can BEL 45Â° metric tube end, type ZMR311, light series, carbon steel be used with crimping machines calibrated for heavy-duty fittings?

No. BEL 45Â° metric tube end, type ZMR311, light series, carbon steel, is specified as a light-series fitting designed for crimping using a crimping sleeve appropriate to the hose type. Crimping machines calibrated for heavy-duty fittings apply different compression force, die profiles and sleeve dimensions than those required for light-series components. Using a heavy-duty calibration risks over-compression, deformation of the cutting ring sealing surface, reduced clamp integrity, damage to the fitting or hose, and potential sealing failure or safety hazards. If you must use a heavy-duty crimper, verify the following before proceeding: - Manufacturer approval or documented compatibility for ZMR311 with the specific heavy-duty machine and dies. - Correct crimping diameter/profile and force settings matched to the light-series sleeve and hose. - Test crimp samples to confirm dimensional tolerances, seal integrity and burst/pressure performance per applicable standards. Best practice: use a crimping machine and dies calibrated for light-series fittings or follow manufacturer guidance to adjust the equipment to the ZMR311 light-series specification.
