Product Overview
Stainless Steel Hydraulic Line Connectors are hydraulic connection components used to join rigid tubes, hoses, valves, manifolds, and hydraulic equipment in fluid systems requiring corrosion resistance and repeated long-term service.
Fluid Connection Benefits
Corrosion Resistance for Demanding Environments
Manufactured in Stainless Steel 304 and 316, with 316 commonly selected for marine, chemical, and washdown
Stable Mechanical Connection
Available with compression, flare, and face-seal connection structures to support hydraulic systems exposed to vibration and pressure variation.
Broad Pressure Coverage
Available for hydraulic systems operating up to 630 bar (9,000 PSI) depending on connector type and size.
Maintenance-Friendly Assembly
Mechanical connection designs allow installation and replacement without welding or re-machining connected components.
Connector Manufacturing Standards
Precision Thread Production
Threads are machined and verified to applicable standards with dimensional control typically maintained within 6H / 6g tolerance classes depending on thread type.
Controlled Sealing Surface Finish
Critical sealing areas are machined to Ra ≤ 1.6 μm to support sealing consistency and reduce assembly damage.
Stainless Steel Material Verification
Raw materials are checked against EN 10204 3.1 certification requirements before entering production.
Burr-Controlled Processing
Machined edges are deburred to reduce installation damage on sealing interfaces and mating components.
Final Dimensional Inspection
Critical dimensions and visual appearance are verified before shipment.

FAQ
Q: What is the difference between a hydraulic line connector and a hose fitting?
A: Hydraulic line connectors are commonly used for rigid tube and system connections, while hose fittings are designed for flexible hose assemblies.
Q: Why choose stainless steel instead of plated steel?
A: Stainless steel provides inherent corrosion resistance without relying on protective surface coatings.
Q: Are stainless steel connectors reusable?
A: Reuse depends on thread condition, sealing surface condition, and installation history.
Q: Which sealing type should be selected?
A: Selection depends on pressure level, media compatibility, maintenance frequency, and system design.
Q: What information should be provided for quotation?
A: Connection standard, thread size, tube or hose dimensions, material grade, pressure requirement, and application environment should be confirmed before ordering.
