A high-flow stainless steel propane pigtail designed to connect dual LP cylinder systems to two-stage regulators. The generous 36-inch length gives you routing flexibility, while the 200,000 BTU/hr flow rating and internal backcheck valve help keep your propane system running reliably without tripping the regulator into bypass mode.
Two-stage LP systems on RVs -- especially those with furnaces, stoves, water heaters, and refrigerators all running simultaneously -- demand consistent pressure and flow. A restrictive pigtail hose is one of the most common causes of a regulator tripping into bypass (also called lockup), which cuts gas supply to the entire rig.
The MB Sturgis 100833-36 addresses this directly. Its 1/4" ID stainless steel reinforced hose assembly delivers up to 200,000 BTU per hour of flow capacity -- well above what most RV appliance loads require -- so your regulator stays in normal operation even during high-demand situations. The dark green RV Type 1 POL-style tank connection integrates a factory-installed internal backcheck valve that prevents propane from escaping if the hose is disconnected under pressure.
200,000 BTU/hr rating reduces risk of regulator bypass lockout during peak appliance demand on dual-cylinder systems.
Corrugated stainless steel inner hose resists kinking, corrosion, and UV degradation better than rubber alternatives.
Dark green Type 1 tank fitting includes a built-in backcheck that stops gas flow if the hose is removed from the cylinder.
Rated from -40F to 140F, making this pigtail suitable for cold-weather camping and hot desert environments alike.
Most two-stage LP regulators include a bypass (or excess flow) safety that shuts off gas if it detects a flow rate consistent with a leak or rupture. Undersized or degraded pigtail hoses can create enough restriction that normal appliance demand mimics an excess-flow condition, tripping the regulator into lockup mode.
The 100833-36's 200,000 BTU/hr capacity gives the regulator adequate headroom. Combined with the stainless steel hose construction -- which maintains its internal diameter without collapsing or swelling like aged rubber -- this pigtail helps prevent nuisance lockouts that leave you troubleshooting a gas system that is actually working as designed.
This pigtail is designed for standard RV LP systems using dual vertical cylinders (typical 20 lb or 30 lb DOT cylinders) connected to a two-stage regulator. The inverted flare 1/4" male fitting on the regulator end is the industry-standard connection used on the vast majority of RV two-stage and auto-changeover regulators. Verify your regulator accepts a 1/4" inverted flare male inlet before ordering.
The inverted flare fitting on the regulator end requires a proper inverted flare wrench to tighten without damaging the seating surface. Do not overtighten. The Type 1 tank connection hand-tightens onto the cylinder valve -- never use pipe thread sealant or Teflon tape on propane flare or POL-type fittings.
The MB Sturgis 100833-36 carries UL569 and ANSI Z21-81 certification, and is UL/CGA approved. These listings confirm the hose assembly has been independently tested for use in portable LP appliance systems and meets the safety requirements for RV and outdoor propane applications. Many campgrounds and RV parks require certified hose assemblies for compliance with their LP system rules.
