Attachment Interface Planning · MERI Machinery

Hydraulic compatibility includes more than connector appearance. Coupler profile and size, pressure rating, flow, hose bore, return back-pressure, case drain, cleanliness, routing and control functions must be confirmed as one system.

Technical Points to Confirm

Coupler standard Confirm profile, nominal size, thread or port, pressure rating and connection under residual pressure.
Flow and hose size Undersized hoses and couplers create restriction, heat and pressure loss during continuous operation.
Return and case drain Hydraulic motors may require low-back-pressure return or a dedicated case drain to protect seals.
Routing Allow articulation and full lift movement while preventing abrasion, crushing, sharp bends and hot-surface contact.
Contamination control Clean caps, couplers and connection procedures help protect valves, pumps and attachment motors.

Information to Include with an Inquiry

  • Carrier model and auxiliary flow
  • Maximum pressure and relief setting
  • Attachment flow and pressure range
  • Required return and case drain
  • Coupler photos, profile and size
  • Hose routing and operating movement
