MB Sturgis 350 PSI Rated UL/CGA Certified High-Pressure Propane Hose -- 3/8" Female Flare Swivel x 3/8" MPT, 48" Long

The MB Sturgis 06-1380 gives you a full 48 inches of rated, certified propane hose to connect your RV or portable propane supply to high-pressure gas appliances -- burners, fryers, generators, and more. With a 350 PSI pressure rating, UL/CGA certification, and US manufacture, this hose meets the performance and safety standards that matter on the road or at the campsite.

Built for High-Pressure Propane Connections

Most low-pressure RV propane lines are rated around 1/2 PSI -- not nearly enough for high-BTU appliances that require full tank pressure upstream of a dedicated regulator. The MB Sturgis 06-1380 is rated to 350 PSI, making it the correct choice when you need to run propane at high pressure from a tank or manifold to an external high-pressure regulator or appliance.

The 3/8" female flare swivel end threads onto standard POL-to-flare adapters, acme-to-flare adapters, and most RV tank valves or manifold ports. The 3/8" MPT (male pipe thread) end connects directly to high-pressure regulators, burner valves, and gas appliance inlets with a standard NPT female fitting. The swivel design on the flare end eliminates hose torque during connection, making routing easier in tight spaces.

350 PSI Pressure Rating

Handles full upstream propane tank pressure safely -- correct for high-pressure appliance runs before a dedicated regulator.

Swivel Flare Fitting

3/8" female flare swivel end eliminates hose twist and makes connecting to tank valves and adapters much easier.

Wide Temperature Range

Rated -40 F to 140 F -- handles cold-weather camping and hot summer days without cracking, stiffening, or softening.

UL/CGA Certified

Meets Underwriters Laboratories and Canadian Gas Association standards -- required by many campgrounds and inspectors.

Thread Compatibility and Fitment

Getting the right fittings matters with propane. Here is exactly what each end of the 06-1380 does:

  • 3/8" Female Flare Swivel (tank side): Threads onto any 3/8" male flare fitting -- including POL-to-flare adapters, ACME-to-flare adapters (with appropriate adapter), and most RV propane manifold flare ports. The swivel allows the hose body to rotate freely once hand-tight, simplifying routing.
  • 3/8" MPT (appliance side): Male pipe thread connects to a standard 3/8" NPT female port on a high-pressure regulator, burner valve, turkey fryer, wok burner, generator gas inlet, or similar high-BTU appliance.

If your appliance has a 1/4" NPT inlet, a 3/8" to 1/4" NPT bushing is required (not included). If your tank valve is a POL type, you will need a separate POL-to-3/8" male flare adapter (not included).

Made in the USA -- MB Sturgis manufactures this hose domestically and backs it with a limited 1-year manufacturer warranty. The hose construction uses a reinforced rubber inner liner rated for liquid petroleum gas, wrapped in a braided reinforcement layer and an outer rubber jacket.

Typical Applications

  • Connecting an RV propane tank or manifold to a high-pressure single-stage regulator
  • Running propane to a high-BTU outdoor burner, turkey fryer, or wok burner
  • Supplying a portable generator with a propane gas inlet
  • Extending propane reach at a campsite where the tank cannot be positioned directly next to the appliance
  • Temporary propane supply hose for trade use and service work
High-Pressure vs. Low-Pressure Hoses: This is a high-pressure hose rated to 350 PSI. It is designed for use upstream of a high-pressure regulator or with appliances that have their own built-in regulator. Do not use this hose as a direct feed to standard RV low-pressure appliances (furnace, water heater, cooktop) -- those systems require a properly set two-stage regulator and low-pressure distribution lines.
Connection Tips:
  • Always apply a leak-detection solution (not pipe dope or Teflon tape) to the MPT threads before connecting to a regulator or appliance inlet.
  • The flare swivel end is a metal-to-metal seal -- do not use thread sealant on flare fittings. Tighten snugly but do not overtighten.
  • Inspect the hose for cracking, brittleness, or damage before each season and before connecting to a new appliance. Replace if any deterioration is visible.
  • Coil loosely for storage -- tight kinks can weaken the inner liner over time.

Important Information
  • This is a HIGH-PRESSURE propane hose rated to 350 PSI. It is not a drop-in replacement for standard RV low-pressure rubber or thermoplastic propane lines.
  • Use only with LP (propane) gas. Not rated for natural gas, compressed air, oxygen, or other gases.
  • Do not use Teflon tape or pipe dope on the female flare swivel end -- flare fittings seal metal-to-metal. Sealant on a flare causes leaks.
  • Inspect before every use. Replace immediately if hose shows cracks, cuts, abrasion, or any visible damage.
  • Maximum temperature rating is 140 F -- keep away from exhaust stacks, open flames, and direct contact with heat sources.
  • Always perform a soap-bubble leak test after making connections and before lighting any appliance.
  • Not intended for permanent buried or concealed installation. For use as an exposed, accessible flex connector only.
  • Keep away from children and store coiled (not kinked) when not in use.
