Suburban High Pressure Propane Hose, 1/4" ID x 3/8" FPT, 3/8" Female Flare Swivel, 144"

Connect your propane tank to your RV's two-stage regulator over extended runs with the Suburban LP-PT144HP 144" High-Pressure Propane Hose. This 12-foot high-pressure hose features a 3/8" female pipe thread (FPT) on one end and a 3/8" female flare swivel on the other, with built-in thermal protection — designed for installations where the tank-to-regulator distance is longer than a standard 6-foot hose can reach.

What This Hose Does

The LP-PT144HP is a high-pressure propane hose for connecting your propane tank to your RV's two-stage regulator over an extended distance:

• End 1: 3/8" female pipe thread (FPT)
• End 2: 3/8" female flare swivel
• Length: 144" (12 feet)
• Inside Diameter: 1/4"
• Pressure: High pressure (pre-regulator side)

Built-In Thermal Protection

The LP-PT144HP includes thermal protection — a safety feature that helps prevent dangerous fuel flow in the event of a fire or extreme heat at the tank or fitting. That's a meaningful safety upgrade over basic propane hoses without thermal protection, and aligns with modern RV safety standards.

When to Use a 144" High-Pressure Hose

A 12' propane hose is typically the right choice for:

• Long tank-to-regulator runs where a 6-foot hose won't reach
• Trailers and toy haulers with tanks mounted far from the regulator location
• Custom installations with separated tank compartments and regulator locations
• Replacement of an existing 144" high-pressure hose
• Installations needing flexibility in routing around obstacles in the propane compartment

If you need a shorter version of the same hose, see the Suburban LP-PT72HP 72" High-Pressure Propane Hose — same connections and thermal protection at 6 feet for shorter runs.

Direct Replacement for Worn Hoses

Propane hoses should be inspected regularly and replaced periodically — most manufacturers recommend replacement every 5-7 years or sooner if you notice cracking, brittleness, or any sign of damage. The LP-PT144HP is a straightforward replacement for worn or aging 144" propane hoses with matching connection types, restoring your propane system to safe operating condition.

⚠️ Professional Installation Recommended

Propane connections should be installed and tested 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.
