Does the DKOR hydraulic end, type ZBW120, carbon steel, zinc-nickel require specific crimping sleeve dimensions for secure hose attachment?

Yes . the DKOR hydraulic end, type ZBW120, carbon steel, zinc-nickel requires an appropriately sized crimping sleeve for secure hose attachment. The product is designed for crimping into hydraulic and industrial hoses using a crimping sleeve suitable for the hose type, so you must use a sleeve whose inner diameter, length and profile match the hose construction (tube, reinforcement, cover) and the fitting tail dimensions. Correct sleeve selection and proper crimping parameters (crimp diameter, swaging profile and machine settings) are essential to ensure mechanical retention, sealing integrity at the 60Â° cone with O-ring and long-term performance. Follow the hose and sleeve manufacturerâs specifications or the crimping chart for the specific hose series; verify crimp dimensions with a calibrated gauge after assembly.

Can DKOR hydraulic end, type ZBW120, carbon steel, zinc-nickel be used with hoses of different pressure ratings without changing the crimping sleeve?

No. DKOR hydraulic end, type ZBW120, carbon steel, zinc-nickel must be crimped with a sleeve matched to the hose type and its pressure rating. The product description explicitly states it is "designed for crimping in hydraulic and industrial hoses using a crimping sleeve suitable for the hose type." Using a sleeve sized for a different hose or different pressure rating risks improper crimp geometry, inadequate seal, and potential failure under pressure. Always use the correct crimping sleeve and follow hose/manufacturer specifications and crimping parameters for the specific hose pressure class.

What is the recommended O-ring material for DKOR hydraulic end, type ZBW120, carbon steel, zinc-nickel to ensure sealing?

For the DKOR hydraulic end, type ZBW120, carbon steel, zinc-nickel, sealing on a 60Â° cone, the recommended O-ring material is nitrile rubber (NBR/BunaâN) with a Shore A hardness of 70. Rationale: - Excellent compatibility with mineral hydraulic oils and typical hydraulic fluids used in systems employing carbon steel fittings. - Good compression set resistance and sealing on metal cone faces at typical hydraulic temperatures (-30 Â°C to +100 Â°C continuous). - Adequate resistance to the zincânickel coating and common additives; low risk of galvanic or chemical adverse interaction. If the application involves extended high temperatures (>100 Â°C), aggressive hydraulic fluids (phosphate esters, fireâresistant fluids), or compatibility with fuels/solvents, consider: - Fluorocarbon (FKM/Viton) for higher temperature and chemical resistance (recommended up to ~200 Â°C, good with many aggressive fluids). - Hydrogenated NBR (HNBR) for improved heat and ozone resistance versus standard NBR. - EPDM only if exclusively water/glycol-based fluids are used (not suitable for mineral oils). Typical O-ring dimensions should match the 60Â° cone groove specified by the DKOR hydraulic end; confirm groove geometry and ensure proper squeeze per manufacturerâs guidelines.
