Clean tubing is critical to the delivery of pure gas to your instrument. Restek’s Stainless Steel Tubing is
specially cleaned for inertness by using the procedure for processing our Silcosteel® and Siltek®-treated
products, because scrupulously cleanparts are aprerequisite for a quality coating.
*The availability of long lengths (continuous lengths up to 500 feet) is subject to inventory constraints. Please inquire before
ordering.
