Recommended Fittings & Clamps

SILVAC offers the excellent temperature resistance of silicone in a vacuum-rated hose (29.9 in./Hg at 70F). The hose construction allows strong vacuum at elevated temperatures; sample testing is recommended.

The construction consists of mandrel-wrapped layers of polyester-reinforced silicone elastomer incorporated around a spiral wound stainless steel reinforcing wire. The wire construction makes SILVAC crush and kink resistant yet quite flexible.

SILVAC is a platinum-cured product, thus reducing extractables.

SILVAC may be low pressure steam sterilized in-line or autoclaved up to 250F in a normal autoclaving cycle. Its smooth bore and the ability to not allow material to stick to the tube wall facilitates easy cleaning and system purging. If exposed to repeated steam sterilization or long-term high temperature or pressure, silicone will eventually relax and become gummy. It should then tbe replaced.

Care is recommended in the selection and application of fittings and clamps for SILVAC as sharp barbed fittings or unlined metal clamps could tear into the wall and possibly cause a failure.

Each length is individually packaged in a heat-sealed polybag and should be sterilized prior to use.

SILVAC is not recommended for implantable or in-body uses or for continuous steam applications.
