Is the DKOS 90Â° hydraulic end, type ZMW222, heavy series, carbon steel, zinc-nickel compatible with standard hose crimping sleeves for industrial hydraulic assemblies?

Yes. The DKOS 90Â° hydraulic end, type ZMW222, heavy series, carbon steel, zinc-nickel is designed for crimping in hydraulic and industrial hoses using a crimping sleeve suitable for the hose type. It features a standard Z-type hydraulic tail for the hose and a heavy-duty construction intended specifically for sleeve crimping assemblies. The internal metric thread and nut with Oâring sealing on a 24Â° cone (DKOS) do not prevent use with standard crimping sleeves . provided you select a sleeve matched to the hose construction and nominal size. Also note the zincânickel coating (6â10 Âµm) gives high corrosion resistance and does not affect crimp compatibility. Always verify sleeve dimensions and crimping parameters from the hose and sleeve manufacturers to ensure a proper, certified crimp.

Does the DKOS 90Â° hydraulic end, type ZMW222, heavy series, carbon steel, zinc-nickel require specific crimping pressure settings for different hose bore sizes?

Yes. The DKOS 90Â° hydraulic end, type ZMW222, heavy series, carbon steel, zinc-nickel requires specific crimping pressure/settings for different hose bore sizes. It is designed to be crimped with a crimping sleeve suited to the hose type, and correct crimp pressure/die selection must match the hose inner/outer diameter and manufacturer crimp specifications to ensure a secure, leak-free connection and avoid damage. Always follow the hose and sleeve manufacturerâs crimping charts and machine settings for the exact bore size; if in doubt, consult the hose supplier or crimping equipment manual.

Can DKOS 90Â° hydraulic end, type ZMW222, heavy series, carbon steel, zinc-nickel be used with O-ring materials other than standard NBR?

Yes. DKOS 90Â° hydraulic end, type ZMW222, heavy series, carbon steel, zinc-nickel can be used with Oâring materials other than standard NBR, but selection must match application conditions. Considerations: - Temperature range: NBR (nitrile) is suitable for approx. â40Â°C to +120Â°C. For higher temperatures use FKM (Viton) or FFKM; for very low temperatures consider HNBR or silicone. - Fluid compatibility: NBR is good for mineral oils and hydraulic fluids. For phosphate esters, strong glycol-based fluids, some bioâoils, or aggressive chemicals choose FKM, EPDM, or FFKM depending on compatibility charts. - Pressure and sealing performance: Hardness and compression set of the alternative Oâring affect sealing on the 24Â° cone; maintain appropriate Shore A hardness (commonly 70Â±5) unless system specifics require otherwise. - Chemical aging and swelling: Some elastomers swell or degrade in certain fluids; verify compatibility with the exact hydraulic fluid and additives used. - Safety/standards: Ensure the chosen elastomer meets industry standards and temperature/pressure ratings for your system. - Installation and mating materials: Metal surface finish (zincânickel coating) is fine, but confirm no galvanic or chemical interactions with the Oâring compound. Recommendation: Consult the Oâring manufacturerâs chemical compatibility and temperature charts and, if possible, perform compatibility tests under actual operating conditions. For critical or highâtemperature/harshâfluid applications, FKM or FFKM are common alternatives; for steam/water/glycol, EPDM may be appropriate.
