BarbLock® retainers.

BarbLock® retainers are the most advanced design available for today's demanding connective applications. When it comes to retaining flexible tubing and hose onto barbed fittings, BarbLock® retainers are the only system with a full 360° radial crimp behind the barb and 360° of compression directly on the barb's ridge.


BarbLock® retainers have become the standard in many industries, including the biopharmaceutical, medical and laboratory, because they solve inherent leak path problems on sensitive and demanding applications. The retainers use no adhesives or solvents and are ideal for systems transferring delicate liquids or gases. The system is quick and easy to assemble saving valuable time.

BarbLock® retainers are constructed from a high performance polypropylene that meets USP Class VI criteria. BarbLock® retainers are also available in high temperature materials for thermally demanding environments.
