Application Cases

Installation Instructions
1.  Clean the inside of the RUBNS-OLC with cleaning cloth and alcohol fluids until the inside is
clean without dust;

2. Connect the pointed plastic mouth to the body of RTV silicone rubber adhesive bottle. See illustration 1 above.

3. Smear RTV silicone rubber adhesive all over the concave channel of the RUBNS-OLC
uniformly as showed in illustration 

4. Uniformly smear the two flat fringes of the concave channel with RTV silicone
rubber adhesive as the illustration 

5,Connect the bulging part of the RUBNS-OLC on one side into the concave channel of the
other side and squeeze the connecting part from one end to the other as illustration 4 indicates
