• Heavy to high capacity designs (up to 125 psig delivery)
• Multiple cylinder gas compatibilities (air, oxygen, inert, acetylene, LP gas)
• Brass or stainless‑steel case options
• Various inlet/outlet CGA configurations

Specifications

• Delivery Range: 2‑200 psig (depending on model)
• Maximum Delivery Pressure: 3000 psig
• Inlet Pressure: up to 3000 psig
• CGA Inlet/Outlet: 9/16‑18" UNF (M/LH/RH) and 5/8‑18" F (LH/RH)
• Case Materials: Brass, Stainless Steel
• Cylinder Diameters: 63.5 mm, 82.6 mm

Applications

• Industrial gas delivery systems
• Welding and cutting operations requiring precise pressure control
• Laboratory and test environments where pressure stability is critical
