Industry-Verified Manufacturing Data (2026)

Hydraulic Connector

Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Hydraulic Connector used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Hydraulic Connector is characterized by the integration of Body and Seal (O-ring/Gasket). In industrial production environments, manufacturers listed on CNFX commonly emphasize High-strength alloy steel construction to support stable, high-cycle operation across diverse manufacturing scenarios.

A specialized fitting that joins hydraulic lines and components within a Blowout Preventer (BOP) system, enabling the transmission of high-pressure hydraulic fluid to actuate critical safety functions.

Product Specifications

Technical details and manufacturing context for Hydraulic Connector

Definition
A hydraulic connector is a precision-engineered component within a Blowout Preventer (BOP) stack, serving as the critical interface between hydraulic hoses, pipes, valves, and actuators. It ensures a leak-proof, high-integrity seal under extreme pressures to reliably transmit hydraulic power for operating rams, annular preventers, and other BOP functions essential for well control during drilling operations.
Working Principle
The connector mechanically joins two hydraulic conduits, creating a sealed passage. It typically employs threaded, flanged, or quick-disconnect mechanisms that compress seals (like O-rings or metal gaskets) against mating surfaces. When assembled and pressurized, the internal seals prevent fluid leakage, allowing hydraulic fluid to flow and transfer force to actuate BOP components.
Common Materials
High-strength alloy steel, Stainless steel
Technical Parameters
  • Maximum working pressure rating, typically ranging from 35 MPa to over 100 MPa for BOP applications. (MPa) Per Request
Components / BOM
  • Body
    Main structural component that houses the fluid passage and provides connection points.
    Material: High-strength alloy steel
  • Seal (O-ring/Gasket)
    Creates a leak-proof barrier between mating surfaces when compressed.
    Material: Nitrile rubber, Viton, or metal
  • Threads/Flange
    Mechanical interface for securing the connection to other components.
    Material: Alloy steel
  • Locking Mechanism
    Secures the connection against vibration and pressure-induced loosening (e.g., lockwire holes, locking collars).
    Material: Steel
Engineering Reasoning
207-345 bar (3000-5000 psi)
517 bar (7500 psi) burst pressure or 0.1 mm radial deformation
Design Rationale: Yield strength exceedance of SAE 1018 steel (414 MPa) or elastomer seal extrusion through 0.05 mm clearance
Risk Mitigation (FMEA)
Trigger Hydraulic fluid contamination with 15 μm particles
Mode: Seal extrusion and leakage at 0.5 L/min
Strategy: Install 10 μm absolute filtration with differential pressure monitoring
Trigger Thermal cycling between -40°C and 121°C
Mode: Elastomer seal hardening (Shore A >90) and cracking
Strategy: HNBR compound seals with 150°C continuous service rating
