BarbLock® Ultra-Secure Retainers

BarbLock® Ultra-Secure Retainers are the most advanced design available in 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 over the barb’s ridge.  BarbLock retainers have become the standard in many industries, including biopharmaceutical, medical, and laboratory, because they solve inherent leak path problems in sensitive and demanding applications. The retainer uses no adhesives or solvents, is ideal for systems transferring delicate liquids or gases, and is quick and easy to assemble, saving valuable time.
