Frequently Asked Questions

Can I use these on rubber hoses?
These tools are primarily designed for steel lines. While they can be used on some hard plastic tubes, their clamping force is optimized for rigid steel pipes. For soft rubber hoses, pinch pliers are usually recommended.
Will the plastic crack from engine heat?
The stoppers are made from high-quality engineering plastic designed to withstand typical under-hood temperatures. However, they should not be exposed to direct flames or extreme welding heat sources.
How do I clean them after use?
Simply wipe off excess fluid with a rag. If they get sticky from old fuel or oil, wash them with warm soapy water and dry thoroughly before storing.
Is the "Banjo" size different from the others?
Yes. The Banjo style has a specialized jaw shape designed to grip the circular head of a banjo bolt fitting, whereas the other three sizes (3/8", 5/16", 1/2") have standard curved jaws for gripping round pipes.
