A reliable, code-compliant propane connection between your POL/Type 1 propane tank and a two-stage regulator. The Suburban 523010 is a 24-inch flexible pigtail hose built with thermal protection and the correct end fittings for direct hook-up -- no adapters required in most standard RV and portable propane setups.
Whether you are running a travel trailer, fifth wheel, or a standalone portable propane system, getting the tank-to-regulator connection right is not optional. The Suburban 523010 uses a Type 1 ACME nut on the tank end -- the same standard OPD-compatible fitting found on virtually all 5 lb to 100 lb propane cylinders sold in North America today -- and a 1/4" inverted male flare on the regulator end, which mates directly with most two-stage RV regulators.
At 24 inches, this pigtail gives you enough slack to prevent stress on fittings when the tank shifts during travel or routine use. The thermal protection sleeve guards the hose body against heat sources and abrasion in tight compartments.
Fits all standard OPD-equipped propane cylinders from 5 lb to 100 lb. Hand-tightenable, no wrench needed on the tank end.
Connects directly to the inlet of most two-stage propane regulators used in RV applications. Standard SAE flare thread.
Factory-installed sleeve over the hose body resists heat and abrasion -- important in enclosed propane compartments.
24" of flexibility absorbs movement and vibration between the tank and regulator, reducing stress on brass fittings over time.
The 523010 is the correct replacement or spare hose for dual-tank or single-tank RV propane systems where the tank connects to an automatic changeover or two-stage regulator. Common scenarios include:
Thread the Type 1 ACME nut onto the propane cylinder valve by hand -- no tools or thread sealant needed on this end. The ACME connection is a left-hand thread; turn counterclockwise to tighten onto the tank valve. On the regulator end, the 1/4" inverted male flare connects with a wrench. Use a backup wrench on the regulator body to avoid torquing the regulator inlet. Do not overtighten -- snug plus a quarter turn is typical for flare connections.
