MCAMPAS Two-Stage Propane Regulator & 12ft Hose Kit for Vent-Free Heaters — 11 in WC, 162k BTU

MCAMPAS F273684 is a complete two-stage regulator and 12-foot hose kit with brass fittings that converts a remote propane tank to vent-free heaters, generators, fryers and other LP appliances.

This assembly replaces single-stage regulators by delivering steadier low-pressure output and higher gas flow for devices that need reliable propane supply. The kit includes a POL tank connector, a 12-foot reinforced hose, a 3/8" female flare swivel, a 3/8" male street elbow and additional brass adapters so you can hook a 20–100 lb tank to vent-free heaters, generators, ranges, and commercial equipment.

How does the two-stage regulator improve performance over a single-stage regulator?

The two-stage regulator separates pressure reduction into two steps to keep outlet pressure stable as the tank empties or demand fluctuates. That results in fewer pressure drops, smoother flame control and better appliance operation when multiple burners or high-BTU devices are in use.

• Delivers consistent 11" WC (1/2 psi) low-pressure output
• Rated up to 162,000 BTU maximum flow capacity
• Reduces cycling and pressure spikes under variable load

What connectors and fittings are included, and why do they matter?

The kit provides a standard POL inlet with a hand-wheel for tool-free attachment, plus a brass 3/8" female flare swivel on the hose outlet. Additional solid-brass adapters—such as 3/8" flare to 3/8" NPT and a 3/8" male street elbow—ensure a durable, leak-resistant connection to a variety of appliances.

• P.O.L. tank connection for direct attachment to LP cylinders
• Brass adapters and 90° elbows for tight or unusual connection points
• Swivel nut on outlet reduces hose twist and eases installation

Which appliances and situations work best with this hose and regulator kit?

This assembly is designed for vent-free heaters and many outdoor or commercial propane devices that accept low-pressure supply. It’s commonly used with Mr. Heater-style vent-free accessories, portable buddies, generators converted to propane, deep fryers, griddles, fireplaces, and RV appliances.

• Compatible with Mr. Heater F273684 vent-free accessories and similar heaters
• Useful for converting generators and powering commercial fryers
• Works with 20–100 lb tanks, suitable for camping, backyard, and commercial use

How difficult is installation and what safety steps should I take?

Installation is straightforward: hand-tighten the POL connector to the tank, route the 12' hose to your appliance, and attach the appropriate brass adapter. Always check for leaks with a soap-and-water solution, follow the appliance manufacturer’s hookup instructions, and keep fittings hand-tight plus a small turn if needed—no power tools required for the POL connection.

• Hand-wheel POL makes attachment tool-free and quick
• Inspect hose for cuts or wear before each use
• Perform a leak test on all joints after assembly

Who is this for: The MCAMPAS F273684 kit is aimed at homeowners, campers, and commercial users who need a robust, higher-capacity replacement for single-stage regulators and a flexible 12-foot hose for vent-free heaters, propane generators, deep fryers, grills and RV systems. Choose this assembly when you want steady low-pressure output, durable brass fittings and the ability to connect larger remote tanks (20–100 lb) to a variety of LP appliances.
