Column End Fittings For Chromatography Analyzer

Column End Fittings For Chromatography Analyzer

Column end fittings are precision-machined connectors installed at both ends of a chromatography column (such as HPLC, UHPLC, or analytical chromatography tubing). Their main function is to securely connect the chromatography column to the flow path of the analyzer—such as the pump inlet, detector, or sampling system—while maintaining leak-free, high-pressure fluid sealing.

 

Typical Thread / Tubing Compatibility:

  1. 1/16" OD tubing (most common for HPLC)

  2. Thread standard often: 10-32 UNF

  3. Internal surface designed to minimize dead volume

  • Working Pressure :

    6000psi (414bar)
  • Material :

    Stainless steel, Alloy, etc.
  • Connection Type :

    Ferrule

Specification:

 

Type Column End Fittings Net Weight 0.1kg
Body Material Stainless steel, alloy, etc. Manufacturing Capacity 4000 pics/Month
Type of Connection Ferrule Warranty 1 year
Connection 1 Dimensions 1/4 Connection 1 Type Ferrule
Connection 2 Dimensions 1/16 Connection 2 Type Ferrule

 

Anhui Hongji (Valvento) Fittings

The design of Column End Fittings incorporates Hongji’s unique technology, ensuring safe, reliable sealing while also offering convenient installation and disassembly. They are often used in high-pressure and high-temperature environments, such as in the chemical, petroleum, and natural gas industries.

 

Applications:

  • HPLC – Connect columns to injectors/detectors.
  • UHPLC – Handle high-pressure connections.
  • GC – Link columns to inlets/detectors.
  • IC – Connect ion exchange columns.
  • Preparative Chromatography – Support large-scale separations.
  • Lab Research – Custom system setups.
  • Industrial Process Control – Ensure reliable online monitoring

Tube Fitting Caps
Tube Fitting Caps

Tube Fitting Caps (Stainless Steel Tube Fitting Caps) are protective end caps used to seal off the end of a tube or tube fitting in instrumentation and fluid system applications. They are part of the dual ferrule tube fitting system , designed to provide a reliable, leak-tight closure for unused ports, tube ends, or temporarily disconnected lines. These caps are installed over the male tube fitting and tightened with a nut to form a secure, metal-to-metal seal using ferrules.   Common Sizes: a. 1/4”, 3/8”, 1/2”, 3/4”, 1” (inch) 6. 6mm, 8mm, 10mm, 12mm, 16mm (metric)

Union Ball Joints
Union Ball Joints

Union Ball Joints (Stainless Steel Union Ball Joints) are mechanical tube or pipe connectors that use a ball-and-socket structure to allow flexible angular movement between connecting lines. This design enables the connection to absorb misalignment, vibration, and thermal expansion without creating leaks.   Common Thread Types: a. NPT Thread: Thread interference (uses PTFE sealant/tape) b. BSPP Thread: Uses O-ring or bonded washer c. BSPT Thread: Thread interference (similar to NPT) d. JIC 37° Flare: 37° metal-to-metal flare seal

Union Elbow
Union Elbow

Union Elbow (Stainless Steel Union Elbow) is a tube fitting designed to connect two tubes at a 90-degree angle while allowing easy disassembly. Unlike a regular elbow, a union elbow has a union nut and ferrules, so the connection can be taken apart without rotating the tubing—ideal for maintenance and tight spaces.     Key Features: a. Material SS316 / SS316L: Excellent corrosion resistance, suitable for instrumentation. b. Union design: Enables easy disconnection and reconnection to modify or service the system. c. Ferrule system: Dual ferrules create leak-tight sealing. d. Tubing size options: Common sizes: 1/8", 1/4", 3/8", 1/2" (or metric). e. Pressure rating: High-pressure capability depending on tube size and standard.

Weld Connectors
Weld Connectors

  Weld Connectors (Stainless Steel Weld Connectors) are tube or pipe fittings designed to be permanently welded to tubing or piping systems, providing a strong, leak-proof, and vibration-resistant connection. Unlike compression or threaded fittings, weld connectors are fused directly to the tube or pipe surface, making them ideal for high pressure, high temperature, or critical sealing applications.   Common Thread Types: a. NPT Thread: Thread interference (uses PTFE sealant/tape) b. BSPP Thread: Uses O-ring or bonded washer c. BSPT Thread: Thread interference (similar to NPT) d.
