Does the DKOL 90Â° hydraulic end, type ZMW221, light series, carbon steel require a specific crimping sleeve size for my hose type?

Yes. The DKOL 90Â° hydraulic end, type ZMW221, light series, carbon steel requires a crimping sleeve that matches the specific hose type and size. The fitting is designed to be crimped into hydraulic and industrial hoses using an appropriate crimping sleeve for that hose; using the correct sleeve ensures proper mechanical retention and a reliable seal with the internal thread, nut and Oâring on the 24Â° cone. Select the sleeve material, profile and internal diameter specified by the hose manufacturer for the hose model and nominal size you are using, and follow the hose makerâs recommended crimp dimensions and crimping procedure. If unsure, consult the hose supplier or the fitting/hose technical datasheets to confirm the exact sleeve type and crimping parameters for ZMW221.

What crimping sleeve diameter is recommended for DKOL 90Â° hydraulic end, type ZMW221, light series, carbon steel when used with my hose?

For DKOL 90Â° hydraulic end, type ZMW221, light series, carbon steel, the recommended crimping sleeve diameter depends on the hose inner and outer diameters and the hose manufacturerâs crimp spec. As a general guideline for light-series metric 24Â° DKOL fittings on common hydraulic hoses: - For hoses with nominal sizes 6 mm (DN6) use sleeve Ã ~16â18 mm - DN8 (8 mm) â sleeve Ã ~18â20 mm - DN10 (10 mm) â sleeve Ã ~20â22 mm - DN12 (12 mm) â sleeve Ã ~22â25 mm - DN16 (16 mm) â sleeve Ã ~26â28 mm Confirm exact sleeve diameter and crimp dimension with your hose maker and the sleeve supplier; verify crimping force and groove specifications for ZMW221 to ensure leak-free, certified crimps.

Is a specific crimping sleeve profile required for DKOL 90Â° hydraulic end, type ZMW221, light series, carbon steel?

No, a specific crimping sleeve profile is not uniquely required for the DKOL 90Â° hydraulic end, type ZMW221, light series, carbon steel. The fitting is designed to be crimped using a crimping sleeve that matches the hose type and size. Therefore you must select a sleeve whose internal diameter, length and profile correspond to the hose manufacturerâs specification and to the hose assembly standard (e.g., EN 853/EN 856 or SAE as applicable). Use a sleeve material and profile recommended for the hose construction (single braid, textile, spiral, etc.) and a crimping machine die set that produces the correct crimp dimensions for that sleeve and hose combination. Key points: - Match sleeve profile to the hose type and sizeânot to the fitting model alone. - Ensure sleeve dimensions and crimping specifications follow the hose makerâs datasheet and applicable standards. - Verify that the sleeve and crimp meet required pressure ratings and sealing integrity for DKOL 24Â° cone configurations. - Use proper crimping tooling calibrated for the chosen sleeve and hose to achieve specified crimp diameter and quality. In summary: choose a crimping sleeve compatible with the hose construction and size; no unique proprietary sleeve profile is dictated solely by the DKOL 90Â° hydraulic end, type ZMW221, light series, carbon steel.
