Barbed connectors
Join flexible and peristaltic tubing easily
Barbed connectors allow direct connection of tubing ends without any threaded fittings, but the tubing walls must be flexible, making this option ideal for peristaltic pump tubing in different materials. Our comprehensive range of barbed connectors comprise barbed-to-barbed, thread-to-barbed, luer-to-barbed, swivel barb, & conical adapters for a wide range of tubing inner diameters.
Biotech Fluidics do also supply a dedicated peristaltic tubing stop adapter which securely hold the tubing in place. This can effectively eliminate the need for fixed stoppers and allow custom cut lengths of peristaltic tubing to be installed on any pump head size.
Peristaltic tubing stop adapters
These unique adapters connect peristaltic tubing to standard 1/16” or 1/8” OD tubing. A specially-designed nose allows the peristaltic tubing to simply press fit over the nose and then be held tightly in place by the retainer sleeve. Your tubing may then be connected with the Flangeless™ fittings supplied with the adapter. To connect your peristaltic tubing to tubing with a different OD, simply replace the supplied fittings with your choice of IDEX 1/4-28 flat-bottom fittings. One popular application for these adapters is to use them as “stops” for your peristaltic pump. By doing so, you can reduce the amount of peristaltic tubing required for your flow path, thus reducing cost.

Conical adapters for peristaltic tubing
Conical Adapters provide a reliable connection between rigid/semi-rigid tubing and peristaltic-type flexible tubing, such as Tygon® and PharMed®. These adapters are composed of a PEEK polymer female nut, the Super Flangeless™ ferrule system and an ETFE or PEEK conical adapter body. The narrow coned end of the adapter body allows peristaltic tubing to slide on more easily than it does onto conventional barbed adapters. Peristaltic tubing is also easier to remove from our Conical Adapters, since no cutting or excessive pulling is required.

Swivel barb adapters
The Swivel Barb Adapters from are made of two captive pieces acting as a one-piece fitting for ease of use. Manufactured from polypropylene (PP) and available in three barb sizes, the Swivel Barb adapters will facilitate connection between flexible (e.g. peristaltic) tubing to a 1/4-28 flat-bottom port. The barbed insert spins freely from the threaded nut in order to prevent the tubing from twisting during installation.

Thread to barbed adapters
These adapters make it easy to connect flexible tubing to any standard 1/4-28 flat-bottom, 5/16-24 flat-bottom, or 10-32 coned receiving port. Simply thread the adapter into a receiving port and slip tubing over the barbed stem to create a reliable low pressure connection.

Luer to barbed adapters
The Luer to Barbed Adapters are an excellent choice when connecting between soft-walled tubing and luer-based products, such as a syringe or a low-pressure filter. We offer several different configurations, allowing you to connect various sizes of soft-walled tubing to receiving ports that accept a male luer slip style connection, or a male luer lock style connection, or a female-luer style of connector.

Barbed-to-barbed unions and Y-connectors
The barbed unions and reducing unions have been engineered to effortlessly join two pieces of flexible soft-walled tubing together, such as two peristaltic tubes with suitable inner diameters. The Barbed Y-connectors are engineered to easily join three pieces of flexible soft-walled tubing together in a Y configuration, offering less turbulence and gentler mixing of fluids than traditional Tee connectors. This type of connector works well for joining three peristaltic tubes with similar inner diameters together. These connectors are manufactured from polypropylene (PP), which due to the low melt point are not autoclavable, however, they can be sterilized via gamma radiation.
