Why Get Our Universal Hydraulic Oil Line Service Rubber Plugs and Caps Kit?

✅Leak-Safe Rubber Fit: Unsealed lines can cause oil leaks and make cleanup a hassle. The Mess Stopper’s snug, flexible rubber plugs seal off lines to help reduce spillage and waste. This helps keep both your hands and work area clean.

✅Universal Fit:  This kit includes small, medium, and large plugs that adapt to a wide range of diameters. That lets you plug most lines without switching kits.

✅Easy to Use: Push and twist to insert—no tools needed. Each plug is hi-vis green/yellow so you’ll notice open connections before starting your system again. This helps prevent reassembly mistakes and keeps your workflow safer.

🌟HOW TO USE

• Select the right size – Choose small, medium, or large based on the hose, port, or fitting size.

• Push and twist – Insert the plug into the unpressurized opening and twist gently to secure a tight seal.

• Remove after service – Once maintenance is done, pull out the plug. Wipe clean and store it in the included zip bag.
