Diba has introduced Microbarb connectors for micro-bore pump and pinch-valve tubing applications.
The chemically inert fittings provide a low-carryover connection between flexible pump tubing and semi-rigid fluoropolymer tubing.
The Microbarb fittings are said to be easy to use, and stretch the inside diameter (ID) over the internal barb while compressing the tubing outside diameter (OD) in the female threaded fitting.
This provides a secure fit, which guards against leaks and carryover.
Constructed of polyaryletheretherketone (Peek) plastic, the fittings are chemically inert and withstand high temperatures and pressures.
The Microbarb works for any soft tubing, including PVC, silicone, Santoprene, Pharmed, Marprene, Viton and Chemsure.
It accommodates all tubing ID sizes from 0.010-0.060in, and OD sizes from 0.062-0.156in.
The reusable, flat-bottom fittings are available in 1/4-28 and M6 fitting configurations and can be ordered by industry-standard pump tubing colour codes.
