Product description

Highlights at a glance

  • Easy installation and handling.
  • Made in high-quality manufacturing.
  • Smooth finish for clean connections.
  • Designed for ultra-high purity gas systems.
  • SUS316L Double Ferrule Straight Union, Zero Micro-Leak Sealing for High-Purity Specialty Gas Tubing
  • Dual Front & Back Ferrule Clamping Design, Vibration & Thermal Cycle Resistant
  • CNC Precision Machining, Smooth Low-Adsorption Inner Bore for Cleanroom Process
  • High-Moly SUS316L Resist Corrosive Gas like Silane & HCl, Anti-Pitting & Rust
  • Weld-Free Quick Assembly, Reusable Design to Save Pipeline Maintenance Time
  • Standard Tube Sizes, Fully Compatible with Regulators, Gas Panels & Metal Hoses
  • Body, double ferrules and nuts all forged SUS316L stainless steel with high molybdenum content, resist hydrolytic corrosive gas such as HCl, SiHCl3 and silane, anti salt spray & acid pitting. Copper-free structure avoids chemical contamination to ultra-pure process gas.
  • Matte passivation treatment forms dense anti-oxidation layer, stable in humid & corrosive workshop atmosphere.
  • Classic double ferrule sealing: front ferrule cuts tube for radial seal, rear ferrule provides axial locking tension. Double clamping prevents slip & leakage under vibration, thermal cycling and minor tube deformation, meet semiconductor helium micro-leak requirements.
  • Ferrule hardness perfectly matched with seamless tubing, no tube crack during tightening, reusable after disassembly to cut consumable cost.
  • CNC machined mirror polished inner bore without burrs or dead zones, ultra-low medium adsorption without metal impurity precipitation. Degreasing, ultrasonic cleaning & nitrogen purge before delivery, oil & debris free for CIP & SIP clean piping.
  • All-metal sealing without rubber O-rings, no swelling or VOC contamination caused by corrosive specialty gas.
  • Weld-free assembly, only two open-end wrenches needed for installation. Fast disassembly for pipeline renovation without tube cutting, greatly shorten construction time.
    • Frequently asked questions

    Our standard lead time is 2 weeks, significantly faster than the industry average of12-20 weeks. We achieve this through modular design and a strategic inventory ofcore components (SS316L bodies, diaphragms). For urgent project needs, pleasecontact our engineering team for "Fast-Track" options.

    Every single product undergoes a rigorous Helium Leak Test using ahigh-sensitivity mass spectrometer. We guarantee a leak rate of less than 1x10-3mbar-l/s. A detailed test report with a unique serial number is provided with eachdelivery.

    Yes. We hold the CE-PED (Pressure Equipment Directive) certification (NB0036/0035 equivalent). This is not just a general CE mark, but a specific safetycertification for high-pressure equipment, which is a mandatory requirement for 90%of industrial projects in Europe (,, etc.).

    We strictly use SS316L (VIM/VAR grade) for ultra-high purity and hydrogenapplications to prevent hydrogen embrittlement. All raw materials come with EN10204 3.1 Mill Test Reports. For corrosive gases, we offer Hastelloy and Elgiloydiaphragm options.

    Absolutely. We specialize in "Lego-style" modular customization. Whether it's a70MPa hydrogen manifold or a semi-automatic changeover system for a lab, ourengineers can provide a professional 3D design and technical datasheet within 24-48nours.

    Yes, we welcome sample orders. We understand that in the semiconductor andenergy sectors, "seeing is believing." You can test our Ra < 0.25um surface finish andoressure stability before committing to a bulk purchase.
