MD70-BR-SIL Medical Grade Silicone Tubing Product Photo

Product Description:

Grayline MD70-BR-SIL is a polyester braid reinforced, peroxide-cured flexible tubing that offers excellent resistance to increased pressure and temperatures. 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 MD70-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. It’s smooth bore and resistance to allow material to adhere to the tube wall allows easy cleaning and system purging. This medical grade hose is manufactured under good manufactured procedures in a controlled environment. Fittings, clamps, sharp barbed fittings, and unlined metal clamps can tear into the silicone tubing wall and should be selected with caution.
