JR Products Gas Cylinder Pressure Regulator
JR Products LP Gas Cylinder Pressure Regulators
When it comes to managing propane safely and reliably in an RV, few components are as critical as the gas cylinder pressure regulator. JR Products has built its reputation as a go-to supplier of RV replacement parts since 1970, and their lineup of gas cylinder pressure regulators reflects that decades-long commitment to quality, safety, and RV-specific engineering.
A Range Built for Every RV Propane Setup
JR Products offers distinct regulator configurations to match the full spectrum of RV propane systems — from compact single-tank trailers to large dual-bottle motorhome setups. Their core lineup includes three primary types:
- Two-Stage Low-Pressure Regulators (Vertical & Horizontal): These are the workhorses of the JR Products regulator family. By combining a high-pressure first stage and a low-pressure second stage into a single unit, they deliver a smooth, continuous flow of LP gas to all onboard appliances. Both vertical and horizontal orientations are available, making it straightforward to match your existing installation. Each features a 1/4" FPT inlet and 3/8" FPT outlet, a 225,000 BTU/hr capacity, zinc die-cast construction with molded rubber diaphragms, and a powder-coated finish for long-term durability.
- High-Pressure Regulator: Designed for high-demand propane equipment, this regulator is primarily suited for dual-bottle PSIG setups where distant separation between tanks and appliances is required. It is rated to regulate up to 500,000 BTU/hr at 30 PSIG based on a 100 PSIG inlet, with a 1/4" FPT connection on both the inlet and outlet.
- Compact Automatic Changeover Two-Stage Regulator: Ideal for RVers who run dual propane tanks and want uninterrupted service, this regulator automatically redirects LP gas vapor from an empty service cylinder to a reserve cylinder without any interruption. A built-in indicator turns red when the service cylinder is depleted and the reserve cylinder engages, so you always know the state of your supply. The service cylinder side is rated at 345,000 BTU/hr, giving it ample capacity for most RV appliance loads.
Built to UL Standards
All of JR Products' two-stage regulators carry UL approval and include a 2nd Stage Relief Mechanism per UL 144 — the industry safety standard for LP gas pressure regulators. They also feature an adjustable screw and dust cap design, helping keep internal components clean and protected between uses. The zinc die-cast body and molded rubber diaphragms are engineered to hold up under the vibration and temperature swings inherent to RV travel.
Why JR Products for Your LP Gas System?
JR Products has spent over five decades focusing exclusively on the RV parts market. Their regulators are not generic off-the-shelf components adapted for RV use — they are purpose-built for RV applications, with connection sizing, mounting orientation options, and BTU ratings that align directly with the appliances found in modern recreational vehicles. Whether you are replacing a worn-out regulator on a vintage trailer or outfitting a new dual-tank setup on a fifth wheel, JR Products offers a model matched to your configuration.
