2 Stage Propane Regulator with POL - Standard P.O.L Connection and 3/8in Female Flare Fitting - Propane Tank Regulator

Key Features

  • Regulation Method: Two-stage design provides a constant 11-inch Water Column (W.C.) pressure for consistent appliance operation.
  • Flow Capacity: Rated for up to 160,000 BTU/hr, suitable for systems with multiple propane appliances.
  • Inlet Connection: Standard P.O.L. (CGA 510) fitting for 20 lb to 100 lb propane cylinders and ASME tanks.
  • Outlet Connection: 3/8-inch female flare fitting for direct connection to propane hoses and supply lines.
  • Construction: Die-cast zinc body with weather-resistant finish.

Replaces / Cross-Reference Part Numbers

  • Direct replacement for regulators with a P.O.L. inlet, 3/8-inch female flare outlet, and a similar BTU rating.
  • Replaces most factory-installed, horizontally mounted two-stage regulators on RVs and trailers.
  • Ensure specifications (BTU, inlet/outlet type and size) match the existing regulator before purchasing.

Compatibility & Fitment

  • Applications: Designed for RVs, motorhomes, travel trailers, campers, and vans.
  • Tank Types: Compatible with 20, 30, 40, and 100 lb vertical propane DOT cylinders and horizontal ASME tanks.
  • Appliances: Supports propane furnaces, water heaters, cooking ranges, refrigerators, and generators.

When to Replace

  • Performance Issues: Inconsistent flame height, popping noises from burners, or yellow, sooty flames on appliances.
  • Visible Damage: Signs of corrosion, cracks, or physical damage to the regulator body or fittings.
  • Leaks: Propane odor detected at or around the regulator after confirming connections are secure.
  • Age: Propane regulators have a typical service life of 10-15 years. Replace based on age or manufacturer recommendations.

Installation Tips

  • Mount the regulator with the vent facing downward to prevent water and debris accumulation.
  • After installation, perform a leak test on all connections using a soapy water solution. Do not use a flame.
  • Do not apply pipe dope or thread sealant to flare fittings.
  • Ensure the regulator vent remains clear and unobstructed during operation.
  • Consult a certified gas technician for installation if you are not familiar with propane systems.

FAQ

This 2-stage propane regulator is intended for LP gas setups that use a standard POL tank connection on the supply side and a 3/8 inch female flare outlet on the appliance or supply line side. It is commonly used with RVs, vans, trailers, campers, generators, 100 lb propane cylinders, and ASME propane tanks, as long as the existing hose or piping matches those connection types and the regulator capacity meets the appliance demand.
POL refers to the traditional propane tank fitting that threads into the internal left-hand threads of a propane cylinder valve. It is different from a Type 1/QCC1 handwheel connection used on many grill tanks. Before ordering, confirm your tank valve accepts a POL fitting and that your downstream connection is a 3/8 inch female flare.
It can work for many RV, trailer, van, and camper propane systems if the system is designed for a 2-stage LP regulator with a POL inlet and a 3/8 inch female flare outlet. The most important checks are the inlet fitting style, outlet fitting style, mounting orientation, and whether the regulator flow rating is sufficient for your furnace, water heater, stove, or other propane appliances.
Typical symptoms include weak or inconsistent flame, appliances that will not stay lit, poor generator performance on propane, gas flow that seems too low, surging, or a noticeable propane smell near the regulator body or fittings. Frost buildup, visible corrosion, or a regulator that has been exposed to contamination or water intrusion can also indicate replacement is needed.
A 2-stage regulator reduces tank pressure in two steps, which helps provide more stable outlet pressure as tank pressure changes with temperature and fuel level. This is especially useful for RVs, campers, trailers, and generator setups where steady propane delivery improves appliance performance and reduces pressure fluctuation.
Verify the tank connection is POL, confirm the downstream line uses a 3/8 inch flare connection, and inspect the hose or tubing for cracks, oil contamination, or damaged flare seats. Also check the vent opening on the regulator and make sure it can be mounted in the correct orientation and kept clear of road spray, debris, and water. After installation, perform a leak test on all connections with an approved leak-detection solution.
Installation is usually straightforward for someone familiar with propane fittings. Typical tools include two appropriately sized wrenches so one can hold the regulator body while the other tightens the fitting. Time is often around 15 to 30 minutes if the connections are accessible. Do not overtighten flare fittings, and do not apply thread sealant to flare-seat connections.
Besides the regulator, inspect the tank valve, pigtail or supply hose, flare fittings, appliance shutoff valves, and burner orifices. Low flow can also be caused by a partially closed service valve, excess-flow activation, hose restriction, contamination in the propane line, or appliance-side issues such as dirty burners or clogged jets.
