Product Overview
Hydraulic Tubing Fitting is a tube connection component used to join rigid hydraulic tubing with valves, manifolds, cylinders, and fluid power equipment while maintaining controlled fluid transfer and service accessibility.
Tube Connection Advantages
Compression and bite-type connection structures create mechanical holding force on the tube surface, helping maintain connection stability under vibration and pressure cycling.
Available in configurations supporting hydraulic systems operating up to 630 bar (9,000 PSI) depending on fitting series and tube size.
Mechanical tube connections eliminate welding operations and allow easier tube replacement during maintenance.
Available in DIN 2353, ISO 8434, SAE, BSP, and Metric connection standards for integration across hydraulic system designs.
Tube Joint Production
Cutting ring profiles are machined with dimensional control within ±0.05 mm to support consistent tube bite during installation.
Threads are manufactured and inspected according to applicable tolerance requirements to improve assembly compatibility.
Critical sealing areas are machined to Ra ≤ 1.6 μm to reduce sealing variation and installation damage.
Incoming materials are validated against applicable certification requirements before production.
Finished parts undergo dimensional and appearance inspection prior to shipment.

FAQ
Q: What is the difference between tubing fittings and hose fittings?
A: Tubing fittings are designed for rigid tube connections, while hose fittings are intended for flexible hose assemblies.
Q: When should tube fittings be selected instead of welded connections?
A: Tube fittings are commonly selected when maintenance access and future replacement are required.
Q: What is the difference between Light Series and Heavy Series?
A: Heavy Series fittings are typically used for higher-pressure systems, while Light Series supports more compact installations.
Q: Can tubing fittings be reused?
A: Reuse depends on thread condition, sealing condition, and the condition of cutting components.
Q: What information should be provided for quotation?
A: Tube OD, wall thickness, thread standard, pressure requirement, material, and application environment should be confirmed before ordering.
