Fisher Twin Stage Regulator

The Fisher Twin-Stage Regulator integrates both first-stage and second-stage regulation into a single compact unit. It reduces high tank pressure to a safe, usable low outlet pressure (roughly 11″ water column) in one assembly. Ideal for domestic propane systems with limited space or where piping distance is short.

Key Features

• Two-stage regulation: first stage reduces high inlet pressure; second stage provides stable low pressure output.

• Outlet pressure rating of approximately 11″ WC (water column) (~0.5 PSI).

• Multiple models available (R232A, R632A) to match load-capacity and connection requirements.

• Designed for high capacity: some models handle up to ~950,000 BTU/hr.

• Durable construction with large vent ports to reduce risk of freezing and allow relief.

• Equipped with inlet/outlet gauge taps to allow system testing and pressure checks.

• Gray colored, straight-through design for ease of installation; compact size helps in confined installations.

• Recommended replacement cycle of about 20 years.

• Keep vent clear and unobstructed for proper function and safety.

• Suitable for domestic and small commercial propane systems.

• Regular inspection is advised: check for vent blockage, check gauge taps, ensure diaphragm and seating remain in good condition.
