BarbLock Ultra-Secure Retainers

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.

  • Compatible with all flexible tubing materials
  • Provides 360˚ radial crimp behind the barb
  • Supplies 360˚ compression over the barb and full dynamic retention

"I received the cart yesterday, thanks for the fast delivery! It feels sturdy. I sat on it. It does not bounce. It is also easy to clean and wipe or wash down."

Testimonial from Chemical Engineer

"Thanks again for reacting so quickly and meeting me halfway with the element. We will be able to get installed and have things keep moving overnight with the night crew. The little things like this are always greatly appreciated when working with Liquidyne."

Testimonial from VP Antibody Manufacturing

“This pump cut our processing time from 3 days to 1 shift. I’m not giving this pump back. You will have to come and get it if you want it... and that won’t likely happen.”
