Suburban 2-Stage Horizontal Propane Regulator, POL Inlet x 3/8" Female NPT, 160K BTU

Regulate propane supply to your RV's appliances with the Suburban LP-R524HP 2-Stage Horizontal Propane Regulator. This high-capacity 160,000 BTU/hr regulator with built-in excess flow device and shut-off valve is the heart of your RV's propane distribution system — stepping tank pressure down to the steady 11" water column needed by your furnace, water heater, stove, and refrigerator.

Two-Stage Regulation for Stable Appliance Performance

Why two-stage matters: RV propane appliances are designed to operate at a precise, low pressure (11" water column). A two-stage regulator delivers that stability across changing tank conditions — full tank vs nearly empty, cold weather vs hot, low demand vs running multiple appliances at once. Single-stage regulators struggle to maintain steady output across those changes; two-stage handles them cleanly, which means your furnace lights reliably, your stove flames stay consistent, and your appliances last longer.

Built-In Safety: Excess Flow Device + Shut-Off Valve

The LP-R524HP includes two integrated safety features:

• Excess flow device — automatically restricts gas flow if a downstream line is cut or breaks (a critical safety feature in the event of a serious leak)
• Shut-off valve — lets you manually shut off propane supply at the regulator for service, transport, or storage

The 1/4" POL inlet includes an excess flow vent for additional protection.

160,000 BTU/hr — Built for Demanding RV Loads

The 160,000 BTU/hr capacity is sized for serious RV propane demand — comfortably handling multiple high-draw appliances running simultaneously (furnace + water heater + range + refrigerator). That's the right capacity for larger RVs, fifth wheels, and any rig where you don't want the regulator to be the bottleneck during peak winter heating loads.

Horizontal Mounting Configuration

This is the horizontal-mount version of the regulator — designed for installations where the regulator mounts horizontally rather than vertically. Confirm your installation's mounting orientation before ordering.

Connection Specs

• Inlet: 1/4" POL (with excess flow vent)
• Outlet: 3/8" female NPT
• Outlet pressure: 11" water column (WC)

Considering Other Suburban/Dicor Regulators?

We carry the full Suburban/Dicor regulator line — pick by application and mounting orientation:

• Suburban LP-R524H — same 2-stage NPT regulator with horizontal vent (for hardpipe horizontal-mount installations)
• Suburban LP-R524V — 2-stage NPT regulator with vertical vent (for vertical-mount installations)
• Suburban LP-R924 — single-stage automatic changeover regulator, 160K BTU/hr (standard capacity for dual-tank installations)
• Dicor LP-R528B — high-capacity automatic changeover regulator, 450K BTU/hr (for larger RVs and high-draw propane systems)

⚠️ Professional Installation Recommended

Propane regulators should be installed and serviced by a qualified service technician to ensure proper leak-free operation. Improperly installed propane hardware is a fire and explosion risk. Always pressure-test connections after installation.
