  • How do Torque-Limiting Nuts protect fluid connections?

    AIIBOOM’s Torque-Limiting Nuts provide an audible "click" once the preset tightening torque (e.g., 0.15–0.25 N·m) is reached. This prevents over-tightening, which can damage plastic threads or deform ferrules, ensuring repeatable, tool-free leak-tight seals.

  • What thread standards do your fittings support?

    Our fittings and port adapters cover standard global industry specifications, including 1/4-28 UNF, 10-32 UNF, 6-40 UNF, 5/16-24 UNF, M6, M5, NPT, and BSPT threads.

  • What is the advantage of the Lock Ring (LR) Series compared to standard flangeless fittings?

    The Lock Ring (LR) Series incorporates a anti-loosening lock ring design that secures the ferrule to the tubing, mitigating loosening caused by equipment vibration during operation or transport. It also reduces friction between the nut and ring, preventing tube rotation during assembly cycles.

  • What fitting systems are available for rigid vs. flexible tubing?

    • Rigid/Semi-Rigid Tubing (PTFE, FEP, PFA, PEEK): We offer Lock Ring (LR) Series Flangeless Fittings, Flanged Fittings, Standard Flangeless Fittings, and Coned High-Pressure Fittings.

    • Flexible Tubing (Silicone, PVC, Pharmed): We provide One-Piece Thread-to-Barb Adapters, Barb-to-Barb Unions/Reducers/Tees/Ys, Panel Mount Barbs, and Quick-Connect Couplings.


  • Does AIIBOOM offer OEM/ODM custom development for proprietary fluidic systems?

    Yes. In addition to our standard catalog items, AIIBOOM operates custom manufacturing facilities and a dedicated engineering team for small-scale and bespoke requests. We support custom tube assemblies, specific thread pitches, specialized wetted materials, custom pump displacement/stroke, and tailored manifold/valve configurations to match your exact system architecture.

  • What industries and applications do AIIBOOM fluid control components serve?

    AIIBOOM specializes in high-precision fluid handling solutions tailored primarily for Medical Devices, Life Sciences, Analytical Chemistry, IVD (In Vitro Diagnostics), Biopharmaceuticals, and High-End Industrial Automation. Our components are widely used in sample preparation, reagent dosing, liquid chromatography, gene sequencing, and automated fluidic systems.
