Critical Purity Manifolds

Critical Purity Manifolds
The modular gas distribution system is a flexible modular manifold Features and Benefits
designed for centralized distribution of high purity gases regard- n Modular Design n Brass
less of facility constraints. Each station has an integral diaphragm Flexible field installation Reduces possibility of gas

facilitates expansion as gas requirements increase. Each system Leak-tight integrity n Metal-to-Metal Joints
comes complete with a flexible, all stainless steel pigtail with Line pressure changeable Easy field assembly and

for a tighter seal. The CGA connection on each pigtail has a Clean installation
check valve in the gland to prevent contamination and minimize
purging requirements.
