HOW TO: Open An Unwelded Oring

 
Our 2 minute video from 2012 shows how to open an unwelded oring using 2 pairs of needle nosed pliers. You must be careful as you can damage the oring with pliers.  Since this video was made I now use 2 pairs of vise-grips locking pliers with both the upper and lower jaws wrapped very well with thin strips cut at about 1" wide x 12" long or more of vet wrap for padding to prevent damage to the oring while opening and closing them.
