A high-flow, safety-rated propane hose engineered to connect a dual LP cylinder system to a two-stage regulator on a travel trailer or RV. At 450,000 BTU per hour, this hose delivers enough flow to keep your system well clear of bypass mode -- even running a furnace, range, and water heater simultaneously.
The MB Sturgis 100883-48 is part of the Type 1 (dark green) hose family, designed specifically for the pigtail connection between an ACME-outlet POL/Type 1 cylinder valve and a dual-stage LP regulator. The 48-inch length gives you extra reach for cylinder cabinets where the regulator is mounted above or offset from the tanks -- a common layout on travel trailers and fifth wheels.
Unlike basic rubber propane hoses, this hose incorporates an internal back-check valve, a stainless steel overbraid for abrasion and UV resistance, and a thermally-activated gas shutoff. These features are not add-ons -- they are built into the hose assembly at the factory in the USA.
Enough capacity to run a furnace, range, refrigerator, and water heater at the same time without triggering the regulator's bypass mode.
Prevents backflow gas leaks when switching or disconnecting cylinders. A critical safety feature on dual-cylinder setups with an automatic changeover regulator.
Protects the inner hose from chafing, road debris, and UV degradation. Significantly extends service life compared to unbraided rubber hose.
Automatically stops gas flow in extreme heat conditions, limiting fire risk if the hose is exposed to high temperatures from an external source.
MB Sturgis color-codes its pigtail hose family to indicate connection type and internal features. The dark green Type 1 hose uses a female inverted flare fitting (1/2 inch) on one end and a male pipe thread fitting (3/8 inch) on the other, with an internal back-check. This matches the standard connection used on most dual-cylinder RV regulator setups with Type 1 (ACME) cylinder valves.
If your current setup uses POL cylinder valves (older style, clockwise-tighten), this is not the correct hose -- you would need the POL-inlet variant. For Type 1 ACME-thread cylinders (the standard on modern DOT propane cylinders sold at most exchange and fill stations), this hose is the correct fit.
If your existing pigtail hoses are cracked, stiff, or more than 5 years old, replacement is strongly recommended. LP hoses degrade from UV exposure, ozone, and heat cycling. The 100883-48 is a direct replacement for most OEM-style dual-cylinder regulator pigtails that use Type 1 connections.
The 48-inch (4-foot) version of this hose works best when your LP cylinders and regulator are separated by more distance than a standard 24-inch or 36-inch pigtail can comfortably span. Common situations include:
Avoid excessive coiling of any extra length -- route the hose smoothly and secure it away from heat sources and moving parts.
