Our Thread to Barbed Adapters are the ideal solution when you need to connect soft-walled tubing with threaded receiving ports - e.g., connecting of peristaltic pump extension tubing to a traditional selection valve used in chromatographic applications. Within this family of products, we offer three different styles of adapters - standard one-piece adapters; one-piece Conical Adapter Bodies; and our Swivel Barb Adapters. (The standard one-piece adapters and Conical Adapter Bodies feature the convenience of a one-piece adapter but also require the barbed stem -- used for connecting the soft-walled tubing -- to spin as the adapter is connected or disconnected. The Swivel Barb Adapters function as one-piece connectors; however, each adapter is comprised of two pieces that spin freely, which prevents the soft-walled tubing from twisting when these adapters are used.) Each of these adapter styles has been engineered to work well with different soft-walled tubing inner diameter ranges.
Our Conical Adapter Bodies offer a great solution for connecting soft-walled tubing of varying ID to a 1/4-28 flat-bottom receiving port. They are manufactured from either Tefzel® (ETFE, for superior chemical resistance) or PEEK polymer (for mechanical strength and reliable chemical compatibility), and they feature a two-stage stem over which you can guide your soft-walled tubing to securely hold it in place.
List of available Conical Adapter Bodies
Primary material of construction | Thread Port Configuration | Thru hole | Thread Gender | For peristaltic tubing inner diameter |
PEEK | 1/4-28 Flat-Bottom | 0.020 inches/0.50 mm | Male | 0.020 to 0.030 inches |

Our Barbed to Threaded Male Adapters make it easy to connect soft-walled peristaltic tubing to several different threaded ports while creating a reliable, low-pressure connection. They are made from inert Tefzel® (ETFE, for superior chemical compatibility) or from PEEK polymer (for good chemical resistance and enhanced mechanical strength).

Our Swivel Barbed Adapters have been engineered for use with soft-walled tubing and are uniquely designed, made of two captive pieces acting as a one-piece fitting. These 1/4-28 flat-bottom barbed connections spin freely from the nut to prevent twist during installation. Manufactured from polypropylene, these are ideal for use with most aqueous solutions.
