PalpitateC Propane Regulator Hose 12ft with POL for Mr. Heater Big Buddy — Brass Fittings, Two-Stage Valve

The PalpitateC F273684 is a 12-foot propane regulator hose assembly with POL connection and two-stage control valve designed to safely link large-capacity tanks to Mr. Heater Big Buddy, portable heaters and multiple propane appliances.

This replacement hose converts a POL-equipped 20–100 lb propane tank to a steady, regulated feed for compatible heaters, grills and RV appliances. Built from durable rubber with solid brass fittings and a two-stage control valve, the F273684 offers extended reach so you can position the tank farther from the appliance for safety and convenience. It’s a non-original-equipment-part (non-OEM) engineered for a tight, tool-free POL connection and standard 3/8" street elbow fittings.

How does this hose keep propane connections steady and leak-free?

The F273684 uses quality materials and precision fittings to create a gas-tight path from the tank to your appliance. A two-stage control valve helps maintain consistent inlet pressure and smooth airflow while the brass joint resists corrosion at connection points.

• Solid brass joint for durable, corrosion-resistant sealing
• Two-stage control valve stabilizes inlet pressure
• High-quality rubber hose resists cracking and flex fatigue
• Threaded POL connection secures to tank without tools

Which heaters and appliances will this F273684 hose work with?

This hose is compatible with Mr. Heater Portable Buddy and Big Buddy series models that accept external tank hookups, and also suits a wide range of camping and RV gear. It connects to common propane appliances that use 3/8" MP x 3/8" MF fittings or a 3/8" female x 3/8" male street elbow.

• Mr. Heater Portable Buddy and Big Buddy series (confirm model compatibility)
• Coleman camping stoves and similar camp appliances
• Blackstone griddles, RV stoves, fire pits, propane fireplaces
• Works with 20–100 lb POL propane tanks (not an OEM part)

How does installation and use look on a campsite or RV?

Installation is straightforward: the POL fitting screws onto the tank without specialized tools and the other end joins your appliance’s inlet via the 3/8" street elbow. With 12 feet of hose length you can safely distance the tank while keeping a secure feed path to the heater or grill.

• Tool-free POL attachment to tank for quick setup
• 12-foot length for flexible tank placement and safety perimeter
• Secure 3/8" fittings for direct connection to appliance inlet
• Recommended: always test for leaks before each use

Who should consider the PalpitateC F273684 hose? Outdoor enthusiasts, RV owners, and anyone using Mr. Heater Big Buddy or similar propane appliances who wants a longer, heavy-duty, POL-compatible hose will benefit from this assembly. It’s aimed at users who need a reliable, weather-resistant connection for larger tanks (20–100 lb) and who are comfortable confirming model compatibility before purchase. Note that this is an aftermarket replacement; verify your appliance’s inlet fitting and model number prior to ordering to ensure correct fit and safe operation.
