Product identity

The Victor Thermal Dynamics 0781-9134 is a single-stage nitrogen regulator built for light-duty purging tasks. It connects to a CGA 580 cylinder via a 0.965"-14 NGO male inlet and delivers gas through a 1/4"-37 flared female outlet. A brass body and neoprene diaphragm handle a maximum outlet pressure of 400 psi. The T-handle provides direct manual control over flow adjustment.

Who it suits

This regulator fits technicians who need a simple, direct-acting unit for nitrogen purging on HVAC or refrigeration lines. The single-stage design means outlet pressure will vary as the cylinder empties, so it is not suited for processes that demand constant delivery pressure. Buyers who require dual-stage regulation or compatibility with gases other than nitrogen should look at alternative models.

What the bundle changes

The unit ships as the regulator body only; no hoses, gauges or cylinder adapters are included. Installers must supply a compatible 1/4"-37 flared hose and any required pressure gauges separately. Because the inlet is a CGA 580 NGO connection, it threads directly onto standard nitrogen cylinders without an extra adapter, reducing the number of separate fittings needed for a basic setup.

Highlights

  • Brass body with neoprene diaphragm resists corrosion from nitrogen flow
  • CGA 580 inlet matches standard nitrogen cylinder connections

Questions about this item

What CGA inlet connection does the 0781-9134 require on the nitrogen cylinder?

The regulator uses a CGA 580 male inlet sized 0.965"-14, so the cylinder valve must match that standard.

Will the 1/4"-37 flared outlet on this regulator connect to my existing 1/4" NPT hose?

No, the outlet is a 37-degree flared tube fitting; an adapter is needed to join it to NPT threads.

After installation, how do I verify the outlet pressure is set correctly for purging?

Adjust the T-handle until the outlet gauge reads the desired pressure up to 400 psi for light-duty purging tasks.
