KF25 clamp with O-ring

KF25 clamp with O-ring

Perfect

Excellent clamp!

This clamping system was a major factor for my purchase of StayFresh over the other guys. I purchased this clamp to attach the 90 degree elbow to reduce stress on the hose between vacuum pump and freeze dryer. The clamp is an easy to use super easy way to attach and seal hose multiple times during routine maintenance.

K25 is the most reliable w/ improved performance

K25 are very reliable and there are no concerns w/ deterioration of a silicone hose over time. They are also very easy to install/remove when necessary.
