Insert Ring, inserted in a tube, prevents the tube from contracting.
Prevent the tubing contraction
Prevents the tube from contracting
Even a very soft tube can be used with the Quick-Fitting joint, if the Insert Ring is inserted in the connecting portion of the tube
Suitable to use with vacuum tube (UD) etc.
The Insert Ring should be installed when a push-in type of fitting is used with water
Insert ring prevents tube contracting from inside. Tubing's pull-out force is increased for tighter tubing lock
