Grayline FB70-BR-SIL is a polyester braid reinforced, peroxide-cured flexible tubing that offers excellent resistance to increased pressure and temperatures. It does not contain sulfur or other acid-producing chemicals. This eliminates the possibility of staining, corroding, or deteriorating other materials it contacts. The design of FB70-BR-SIL allows an excellent bend radii and permits installation in restricted spaces. It can be low pressure steam sterilized in-line or autoclaved at up to 250°F in a normal autoclaving cycle. However, it will relax and become gummy after it has been exposed to multiple sterilizations and should be replaced. Long term exposure to high temperature or pressure will also have the same effect on the tubing.
Grayline FB70-BR-SIL is well suited for increased pressure food contact applications because it is odorless, tasteless, inert and is made from 100% FDA-sanctioned ingredients. Fittings, clamps, sharp barbed fittings, and unlined metal clamps can tear into the silicone tubing wall and should be selected with caution.
