Easy-to-use Connection Fitting for Soft Tubing

For micro-bore pump and pinch valve tubing applications, Diba has introduced MicroBarb™ connectors. The chemically inert fittings provide a low-carryover connection between flexible pump tubing and semi-rigid fluoropolymer tubing. Easy-to-use MicroBarb fittings stretch the inside diameter (ID) over the internal barb while compressing the tubing outside diameter (OD) in the female threaded fitting, for a secure fit that 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 to 0.060 inches, and OD sizes from 0.062 to 0.156 inches. The reusable, flat bottom fittings are available in ¼-28 and M6 fitting configurations and can be ordered by industry-standard pump tubing colour codes.
