Application Scenarios

Ultra-High Integrity Services Connections (DISS) are used to connect gas-handling equipment such as pressure regulators or pigtails directly to the cylinder valve outlet of a semiconductor or high-purity gas cylinder. This collection supports DISS cylinder-valve connection and gasket replacement workflows; specific gas service, equipment, site, and compliance requirements should be confirmed with LITEN before selection.

Model Selection Guide

Select the required gas-to-UHP-CGA/DISS designation within the 630–728 range, then confirm the applicable NI or PCTFE material option, cylinder valve, equipment connection, and dimensions with LITEN before ordering.
