Frequently asked questions
What pressure range do SITEC-Sieber products cover?
The range depends on the product family. Valves, fittings and tubing are available for pressures up to 10,000 bar; the pressure range of each product is listed on its page.
Which applications are the products used for?
Typical uses are hydrogen and energy research, supercritical extraction (SFE), micronization and spray drying (RESS/GAS), high-pressure processing (HPP), autofrettage and test benches in laboratories and pilot plants.
How do I get a quotation or product selection support?
Use the quotation form or the Request a Quote tab. Please state the catalogue page number if you know it, plus operating pressure, temperature, fluid and connection type; this speeds up the evaluation.
Where can I get the detailed catalogue and model tables?
The H2X product pages summarise each family. For model and order-number tables, request the datasheet from the product page or contact us.
