Pure-Fit® SIB® Smooth Inner Bore Systems

Pure-Fit® SIB®

Pure-Fit® SIB® is a smooth inner bore (SIB) hose-barb connector that provides a seamless transition between tubing and fittings throughout the fluid path.

Pure-Fit® SIB® eliminates entrapment and leak points that can occur with traditional assembly systems.

The unique internal design eliminates voids or dead space that can lead to turbulence or stagnation of fluid flow creating the potential for bacterial growth.
