Product Overview

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.

Pure-Fit® SIB® fittings are fully compatible with Pure-Fit and BarbLock® retainers that provide complete 360° compression for leak-free connections.

Pure-Fit® SIB® fitting systems meet all USP Class VI and ISO criteria and have been physically tested to meet the most demanding applications and stringent test protocols.

Available in both animal-free and BPA-free polypropylene (PP) and polyvinylidene fluoride (PVDF) materials, Pure-Fit® SIB® provides a seamless transition that maintains complete fluid integrity when used with Saint-Gobain’s Bio-processing Tubing series, such as Sani-Tech®, C-Flex®, and PharMed®, etc. flexible tubing.
