629 Series MicroManifold

Compact manifold system for industrial gas applications
6291064-01-540 shown

The 629 Series MicroManifold is a flexible, non-corrosive gas distribution system that can be configured as a gas or vent manifold. Configured as a gas manifold, the 629 offers excellent gaseous flow capacity from either liquid or high pressure cylinders to a CONCOA pressure control device. Configured as a vent manifold, the 629 MicroManifold equalizes the headspace pressure of each liquid cylinder manifolded together. This allows each cylinder to withdraw equally and operate at maximum flow capacity with minimal loss. The 629 Series MicroManifold is compatible with many CONCOA 500 Series or 600 Series switchovers for a flexible system design.

  • Vent manifold excess flow orifices prevent hoses from whipping
  • Safety disk protects manifold from overpressurization
  • Compact modular design provides easy field expandability
  • Multiple cylinder hose options support universal gas compatibility
  • Integrated 1/2 in MNPT outlet connector reduces potential leak sites
  • Max inlet pressure: 4500 PSIG (310 BAR)
  • Temperature range: -320°F to 165°F (-195°C to 75°C)
  • Inlet connections: 1/4 in FNPT
  • Outlet connections: 1/2 in MNPT
  • Manifold block: Brass barstock
  • Weight (manifold and bracket): 14.5 lbs (6.5 kg)
  • Hoses: Brass, copper, or stainless steel
  • Hose core: Monel®, brass, copper, stainless steel, or PTFE
  • Conformances: Cleanliness meets or exceeds CGA G-4.1; CRN OH15806.5 (Body); CRN OD18143.5 (Hoses)
