Barbed Connectors

Idex Barbed Connectors

Idex Barbed Connectors provide simple, reliable solutions for joining soft-walled tubing in low-pressure fluid handling applications, including peristaltic pumping, sample transfer, and general laboratory workflows. Designed for secure tubing engagement without tools, these connectors support efficient fluid routing while minimizing leaks and flow disruption.

This product family includes multiple barbed connector styles engineered to accommodate common tubing configurations and inner diameter requirements.

Barbed Y Adapters are designed to join three pieces of soft-walled tubing in a Y configuration, providing gentler fluid merging and reduced turbulence compared to traditional tee connectors. These adapters are ideal for combining peristaltic tubing lines with similar inner diameters and are manufactured from durable polypropylene.

Barbed Reducing Adapters allow secure connections between two pieces of soft-walled tubing with different inner diameters. Commonly used for transitioning between peristaltic tubing sizes, these adapters are available in polypropylene or nylon for broad chemical compatibility.

Barbed-to-Barbed Adapters (Type 1 Barbed Unions) provide straightforward connections between two pieces of similarly sized soft-walled tubing. These unions are frequently used in peristaltic pump systems and general fluid transfer applications and are manufactured from polypropylene or nylon.

Key Definitions â–¸
Barbed Connector
A fitting with one or more ridged barbs designed to securely grip soft-walled tubing by friction, creating a leak-resistant connection without the need for clamps or tools in low-pressure systems.
Barbed Y Adapter
A Y-shaped barbed connector used to join three pieces of soft-walled tubing together, offering reduced turbulence and smoother fluid merging compared to traditional tee-style connectors.
Barbed Reducing Adapter
A barbed fitting designed to connect two pieces of soft-walled tubing with different inner diameters, commonly used to transition between peristaltic tubing sizes in fluid handling systems.
Barbed Union
A straight barbed connector used to join two pieces of soft-walled tubing with the same inner diameter, providing a simple and secure inline connection.
Soft-Walled Tubing
Flexible tubing materials such as silicone, Tygon®, or other elastomers commonly used in peristaltic pumping and low-pressure fluid transfer applications.
Frequently Asked Questions â–¸
What tubing materials are compatible with Idex barbed connectors?
Idex barbed connectors are designed for use with soft-walled tubing such as silicone, Tygon®, and other flexible elastomeric materials commonly used in peristaltic pumping and low-pressure fluid transfer applications.
When should I use a barbed Y adapter instead of a tee connector?
Barbed Y adapters are preferred when gentler fluid merging is required, as the Y geometry reduces turbulence and backpressure compared to traditional tee-style connectors.
Are barbed reducing adapters suitable for different tubing sizes?
Yes. Barbed reducing adapters are specifically designed to connect soft-walled tubing with different inner diameters, making them ideal for transitioning between tubing sizes in peristaltic and low-pressure fluid systems.
Do Idex barbed connectors require clamps for secure connections?
In most low-pressure applications, clamps are not required, as the barbed design provides a secure friction fit. However, clamps may be recommended for higher flow rates or applications with softer tubing materials.
