Application Cases




 


Installation Instructions


● Clean the inside of the RUBNS-OLC with cleaning cloth and alcohol fluids until the inside is clean without dust;

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


 Smear RTV silicone rubber adhesive all over the concave channel of the RUBNS-OLC uniformly as showed the 2 above

 Uniformly smear the two flat fringes of the concave channel with RTV silicone rubber adhesive as the illustration 3 shows



 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.
