Step #1. Prepare tools

It will be advantageous to use a specific tool that will help you loosen the connection between the joints. All you need is a wrench, tweezers or nose fliers,  penetrating oil or lubricants, and preferably, a table-top vise grip. Then, remove the wand using a wrench or a table-top vise grip. You can also use a glove to protect your hands.


Step #2.  Remove old o-rings

After removing the wand, you can now remove the old o-ring. The o-rings can quickly determine the o-ring, as it is a black and circle-shaped rubber located in the groove.

If your old o-rings break, it’s okay. You won’t need it anyway. After you successfully remove it, you can also clean the joining points with a white piece of cloth to remove any dust, grime, and rust.  


Step #3. Attach the new o-ring

In handling your new o-rings, you must carefully attach them. O rings are sensitive and easily break off. So, it’s better to insert or attach them into the groove slowly but securely. If your lubricant or oils dried up after you cleaned the inside with a cloth, you can put a small amount inside to help you push down the o-rings. Slowly put the o-ring on the surface and push it down using a tweezer or nose fliers. If you do not have a tweezer and nose pliers at home, you can substitute them with another tool that can go through the hole. Push until it is settled securely into the groove.


Step #4. Reinstall the wand

It is the last step in a row, reinstalling the joints. After you have successfully installed the new o-ring to its place, you can now proceed into attaching each end.
