Thermoplastic high-pressure propane hose with 1/4" male pipe thread on one end and a 3/8" female flare swivel on the other. 60" overall length. Built for regulator, distribution block, and appliance connections in RV, generator, and outdoor gas appliance systems.
MB Sturgis has manufactured LP and natural gas hose assemblies, connectors, and quick disconnects for over 30 years, supplying many of the largest OEMs in the RV, BBQ grill, patio heater, and standby generator industries. The 100038-60-MBS is a 60" high-pressure thermoplastic LP gas hose built to that same standard — a durable, flexible connection designed for the demands of propane delivery systems where reliable sealing and consistent flow matter.
This hose terminates in a 1/4" male pipe thread (MPT) fitting on one end and a 3/8" female flare swivel fitting on the other — a configuration commonly used to connect a regulator outlet, distribution block, or gas appliance inlet rather than a tank-side pigtail connection. The swivel design on the 3/8" flare end allows for easier alignment and tightening during installation without twisting the hose body. Built from quality thermoplastic construction, the 100038-60-MBS is engineered for durability across the temperature ranges and outdoor conditions typical of RV and appliance gas systems.

Propane hose fittings vary by application, and an incorrect match can result in a leak or failed connection. Before ordering, confirm: 1. Fitting type at each end: This hose has a 1/4" male pipe thread (MPT) connection on one end and a 3/8" female flare swivel on the other. Confirm these match the fittings on your regulator, distribution block, or appliance. 2. Application: This hose configuration is typically used for regulator-to-appliance or regulator-to-distribution-block connections — not for tank-to-regulator (pigtail) connections, which generally use a POL fitting on the tank side. 3. Length: Confirm 60" is the correct length for your installation. MB Sturgis offers this hose style in multiple lengths for different routing needs. If you are unsure which hose configuration your system requires, consult your appliance or regulator's installation documentation, or contact MB Sturgis directly.
Installation Steps: 1. Shut Off Gas Supply: Close the gas supply at the tank or source before beginning any installation or replacement work 2. Verify Fitting Compatibility: Confirm the 1/4" MPT and 3/8" female flare swivel ends match your regulator, distribution block, or appliance fittings 3. Apply Thread Sealant: Use an appropriate gas-rated thread sealant on the 1/4" MPT connection per standard practice 4. Connect Fittings: Thread the MPT end into its mating connection and tighten the 3/8" flare swivel onto its mating fitting 5. Tighten Securely: Tighten both connections to a secure, leak-free fit without overtightening 6. Leak Test: Restore gas supply and perform a soap-and-water leak test on both connections before use Gas line work should be performed or verified by a qualified technician. Always leak-test connections before placing the system into service.
