Barbed fittings provide secure, leak-resistant connections between your plastic fluidic manifold and flexible tubing in OEM devices. Controlled Fluidics offers straight, elbow, and low-profile barbed fittings engineered for compact, high-performance manifolds in microfluidics, diagnostics, and industrial fluid control systems. Our engineering team helps you select the right barb and fitting configuration so your manifold assembly is robust, serviceable, and production-ready.

WHY BARBED FITTINGS FOR MANIFOLDS?

Choosing how to connect your manifold to tubing impacts leak risk, serviceability, and overall device performance. Barbed fittings are commonly used in microfluidics instruments, analytical systems, medical devices, and industrial fluid control equipment where reliable, repeatable tube-to-manifold connections are required for several reasons:

  • Secure grip between barb and flexible tubing to reduce leaks under pressure and vibration.
  • Durable 303 stainless steel construction for corrosion resistance in contact with fluids, moisture, and cleaning agents.
  • Compact geometries (elbow and low-profile styles) that preserve tight manifold layouts and enable higher channel density.
  • Configurable barbed sizes, thread types, and orientations to match manifold porting and tubing IDs across OEM platforms

BARBED FITTING OPTIONS

Barbed Straight.webp

Barbed Straight Fittings

Straight barbed fittings connect tubing directly to manifold ports when there is sufficient vertical clearance above the device.
Barbed Elbow.webp

Barbed Elbow Fittings

Barbed elbow fittings redirect flow at a right angle, supporting compact manifold layouts where vertical straight fittings are impractical.
Barbed Elbow - Low Profile.webp

Low-Profile Barbed Elbow Fittings

Low-profile barbed elbow fittings are designed for instruments and manifolds where vertical clearance is extremely limited.

MORE ABOUT BARBED STRAIGHT FITTINGS

Straight barbed fittings connect tubing directly to manifold ports when there is sufficient vertical clearance above the device. These fittings are typically machined from 303 stainless steel to deliver high strength and corrosion resistance for demanding environments. Other benefits include:

  • 303 stainless steel construction for long service life in contact with chemicals and cleaning fluids.
  • Barbed end designed to grip flexible tubing and maintain a leak-resistant seal under normal operating pressures.
  • Threaded stud interface that integrates cleanly with bonded plastic manifolds and other fluidic components.
  • Typical applications: analytical instruments, microfluidics test stands, and industrial dosing systems.

MORE ABOUT BARBED ELBOW FITTINGS

Barbed elbow fittings redirect flow at a right angle, supporting compact manifold layouts where vertical straight fittings are impractical. The adjustable elbow design allows installers to orient the barb precisely to simplify tubing routing and maintenance. Other benefits include: 

  • Adjustable elbow provides right-angle flow direction and fine orientation control in tight spaces.
  • 303 stainless steel body and slotted stud enable robust installation using standard tools. 
  • Buna-N O-ring and barbed end work together to create a reliable, leak-resistant connection. 
  • Frequently used in microfluidics, analytical instrumentation, and medical and industrial fluid systems where panel height is limited.

MORE ABOUT LOW-PROFILE BARBED ELBOW FITTINGS

Low-profile barbed elbow fittings are designed for instruments and manifolds where vertical clearance is extremely limited but precise fluid direction is still required. The compact geometry and dual O-ring sealing provide reliable performance in densely packed OEM designs. Other benefits include: 

  • Low-profile geometry minimizes stack height above the manifold, enabling tighter packaging inside enclosures.
  • Dual Buna-N O-rings add redundancy for enhanced leak prevention under pressure changes and thermal cycling.
  • 303 stainless steel construction offers strength and resistance to corrosion and oxidation.
  • Well suited to space-constrained microfluidic analyzers, portable diagnostic devices, and compact industrial systems.

TYPICAL APPLICATIONS & USE CASES

Barbed fittings support a wide range of fluidic applications where flexible tubing connects to plastic manifolds, distribution blocks, or custom OEM assemblies. These use cases show where barbed manifold fittings improve reliability, simplify service, and support repeatable manufacturing at scale.

  • Microfluidics & analytical instrumentation: Connecting disposable tubing sets to manifolds for sample handling, reagents, and waste lines.
  • Medical & laboratory devices: Ensuring stable connections in diagnostic analyzers, life-science instruments, and benchtop systems. 
  • Industrial & process systems: Routing fluids through control manifolds in chemical processing, dosing, and cooling loops

SELECTING THE RIGHT BARBED FITTING

Selecting the correct barbed fitting for your components depends on tubing, space, fluid, and pressure requirements. All these combined points generally in the right selection for your product. 
  1. Tubing Material & ID:
    Confirm tubing inner diameter and compatibility with the barb geometry to achieve a secure mechanical grip and seal.
  2. Available space & orientation:
    Determine whether a straight, elbow, or low-profile elbow is needed based on enclosure height and tubing routing.
  3. Fluid properties & environment:
    Verify that 303 stainless steel and Buna-N O-rings are compatible with your fluids, cleaning agents, and operating temperatures.
  4. Pressure range & safety margin:
    Match barbed fittings to the system pressure, including spikes and potential vacuum conditions, to maintain leak resistance.
  5. Assembly & Service requirements:
    Consider the need for tool access, adjustability, and field replacement when choosing fitting style and orientation.

Controlled Fluidics reviews these parameters during product design reviews to recommend fittings that align with your performance, regulatory, and manufacturing goals.
