These single station manifolds (also known as "protocol stations") are designed to provide a safe, reliable method of wall-mounting a single cylinder regulator, eliminating the need to handle the regulator during cylinder change out. Brackets are fabricated from 304 stainless steel for durable, long-life service and are suitable for connecting most single and two-stage regulators. Easily mount to wall or existing structure. The manifolds are provided with 30" stainless steel (corrugated bellows) flexible pigtails and CGA connections with check valves to prevent contaminants from entering during cylinder change-out.
