Gas Regulators / Tubing
Dual-StageUltra-High-PurityChrome-PlatedBrassRegulators
• Oxidation-resistant, chrome-plated.
• Most stable outlet pressure control throughout the life
of ahigh-pressure gas cylinder.
• Secondarypressure regulationnot needed.
• Mostwidelyused regulator.
• Less internal volume than stainless steel regulators.

Instrument-GradeWeldedandDrawn304GradeStainlessSteelTubing
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.
