Dibafit™
barbed adaptors are designed for use with soft-wall tubing. Machined from chemically resistant PEEK™ or acetal they have a superior barb with a crisp edge that retains soft wall tubing more securely than molded adaptors. A tight, leak-free connection can be ensured by matching the ID of your tubing to the barb size of the adaptor. If there is not an exact match, always choose the barb size that is just larger than your tubing ID. To connect softwall tubing into any female 1/4”-28 UNF port, use a male ¼”-28 UNF to barb adaptor.
The male
thread screws into the port and tubing can then be pushed over the barb. To connect softwall tubing to any male 1/4”-28 UNF thread, use a female 1/4”-28 UNF to barb adaptor.The barb is inserted into the softwall tubing and the female ¼ UNF port is available to receive any ¼”-28 UNF threaded fitting. Connecting a male and female adapter allows to create a customzied barbed to barbed adapter.
