About This Product
A Hoffman clip closes off a length of tubing without the tube having to be pulled off the apparatus. Tightening the screw pinches the sides of the tube together to block the flow of air or gas, the projection plate stops the end of the screw from damaging the tubing, and the hinged bar means the clip can be added to tubing already connected at both ends.
Frequently Asked Questions
Can the clip be fitted to tubing already connected to apparatus?
Yes. The hinged bottom bar allows the clip to be fitted and removed without access to the ends of the tube.
