Product Overview
Hydraulic Fittings And Flanges are hydraulic connection components used to join hoses, tubes, valves, pumps, cylinders, and manifolds within hydraulic fluid power systems. They provide threaded, flanged, or sealed connection points for fluid transfer across mobile and industrial equipment.
Connection System Advantages
Broad Pressure Coverage
Available for hydraulic systems ranging from low-pressure return lines to applications operating up to 420 bar (6,000 PSI), depending on connection type and standard.
Standardized Interchangeability
Manufactured according to widely adopted standards including SAE J518, ISO 6162, ISO 8434, DIN 2353, and JIC 37°, supporting integration across globally sourced hydraulic components.
Reduced Leakage Paths
Flange face seals, O-ring seals, and metal-to-metal sealing interfaces help minimize potential leak points compared with improvised connection arrangements.
Flexible System Layout
Supports straight, elbow, tee, cross, bulkhead, and flange connection designs, allowing hydraulic circuits to be configured around equipment space constraints.
Production & Inspection Framework
Forging and Bar Stock Processing
Components are produced from hot-forged blanks or precision-machined bar stock depending on product type and pressure requirements.
Multi-Stage CNC Machining
Threads, sealing surfaces, flange faces, and critical dimensions are machined through dedicated CNC operations to maintain dimensional consistency.
Standard Compliance Verification
Connection dimensions are inspected against applicable SAE, ISO, DIN, and JIS specifications before release.
Surface Protection Control
Coating thickness, appearance, and coverage are checked throughout the finishing process to verify corrosion-protection performance.
Traceable Manufacturing Records
Material certificates, production batches, machining records, and inspection reports are maintained for product traceability.

FAQ
Q: How do fittings and flanges differ in hydraulic systems?
A: Fittings typically use threaded or compression-based connections, while flanges use bolted connections with O-ring sealing and are often preferred for larger sizes and higher flow rates.
Q: When should a flange connection be selected?
A: Flanges are commonly used when hydraulic circuits require high flow capacity, larger connection sizes, or frequent maintenance access.
Q: Which standards are most commonly specified?
A: SAE J518, ISO 6162, DIN 2353, ISO 8434, BSP, NPT, JIC, and ORFS standards are among the most widely used in hydraulic systems.
Q: How can compatibility be confirmed?
A: Thread standard, sealing method, pressure rating, connection size, and installation requirements should all be verified before selection.
Q: What information helps speed up quotation requests?
A: Providing part numbers, dimensional drawings, connection standards, material requirements, pressure ratings, and annual demand estimates helps ensure accurate product selection and pricing.
