Vertical design pliers work best for straight-on, easy to reach locations
Angled design pliers are great for tight fitting, under the hood applications
Use the small pliers for 1/8" to 3/8" O.D. lines; use the large pliers for 3/8" to 3/4" O.D. lines
Specially designed to detach push-to-connect type air brake fittings
Additional applications include fuel lines and filters, vacuum lines, coolant lines, PCV valves and wiper tubing
Easy to use simply slide the pliers over the line so the pusher is against the fitting; as you squeeze, the gripper will grab and pull the line in the opposite direction of the fitting until it is released
WARNING: Be sure to release all pressure, air or fluids from lines before using quick-release pliers.
