Is the DKOS hydraulic end for UHP heavy series hose, carbon steel, type PMW122 compatible only with specific crimping sleeves and thermoplastic hose models?

DKOS hydraulic end for UHP heavy series hose, carbon steel, type PMW122 is intended specifically for use with UHP thermoplastic hoses and must be crimped using a crimping sleeve that is suitable for that hose type. Its design . a special âtailâ for thermoplastic hose and internal metric thread with Oâring sealing on a 24Â° cone . means compatibility is limited to matching thermoplastic hose models and the correct crimping sleeves specified for those hoses. Using incompatible sleeves or nonâthermoplastic hose types can compromise the crimp, sealing and safe operation. Always follow the hose and sleeve manufacturerâs specifications to ensure proper fit and performance.

Can DKOS hydraulic end for UHP heavy series hose, carbon steel, type PMW122 be used with stainless steel crimping sleeves or only galvanized ones?

DKOS hydraulic end for UHP heavy series hose, carbon steel, type PMW122 is specified as carbon steel, galvanized, and designed to be crimped using a sleeve suitable for the thermoplastic UHP hose. Because the fittingâs base material is galvanized carbon steel, the manufacturerâs description implies compatibility with crimping sleeves intended for that hose type-typically matching materials or coatings that avoid galvanic corrosion and ensure proper mechanical behavior after crimping. Using stainless steel sleeves can introduce galvanic corrosion risks between stainless and galvanized carbon steel, and may alter crimping characteristics (hardness, compression). Unless the manufacturer explicitly approves stainless sleeves for PMW122, use the recommended galvanized or specified sleeve material for that hose type.

Can DKOS hydraulic end for UHP heavy series hose, carbon steel, type PMW122 be used with reusable crimping sleeves?

Yes. with conditions. Details: The DKOS hydraulic end for UHP heavy series hose, carbon steel, type PMW122 is described as a heavy-duty, crimped fitting for UHP thermoplastic hoses, designed to be crimped using a crimping sleeve suitable for the hose type. That means the fitting itself is compatible with a sleeve-based crimp assembly. However, âreusable crimping sleevesâ typically refer to mechanically reusable or clamp-style sleeves (not permanent swaged/crimped sleeves). Whether a reusable sleeve can be used depends on three factors: 1) Hose manufacturer approval: The hose maker must certify that their UHP thermoplastic hose can be assembled with a reusable sleeve and that the sleeve type is compatible with the hose construction and pressure rating. 2) Sleeve design and dimensions: The reusable sleeve must match the outer diameter, profile, and clamping geometry required by the DKOS end and the hose. The PMW122 fitting expects a sleeve âsuitable for the hose typeâ; if a reusable sleeve meets those dimensions and provides the required compression on the fitting tail, it can be used. 3) Pressure, safety and standards: Reusable sleeves may have different performance (burst, impulse, vibration resistance) than permanent crimped sleeves. For UHP applications you must verify the assembly meets required pressure ratings, safety standards and testing (burst/impulse) for the system. Conclusion: The DKOS hydraulic end for UHP heavy series hose, carbon steel, type PMW122 can be used with reusable crimping sleeves only if the specific reusable sleeve is approved for that hose and fitting combination and meets the required dimensional, pressure and safety specifications from the hose and fitting manufacturers. Always follow manufacturersâ assembly instructions and validation/testing requirements.
