NRGR02 Adjustment Spring for Norgas Regulators

Selecting a NRGR02 Adjustment Spring is one of the most important parts of setting outlet pressure. Each spring color corresponds to a specific outlet pressure range, allowing precise and stable gas pressure control for natural gas, LP gas, and other non-corrosive fuel gases.

The Orange spring (2”–7” W.C.) is one of the most commonly selected ranges for low-pressure natural gas appliance applications such as boilers, rooftop units, heaters, and similar equipment, depending on system design requirements.

NGR02 Spring Ranges & Part Numbers

Orange Spring (S02F) — 2” W.C. to 7” W.C.

The most common outlet pressure range used in modern commercial and residential gas systems. Ideal for standard appliance regulation and general-purpose gas service.

Green Spring (S02A) — 6.5” W.C. to 16” W.C.

Used when slightly higher outlet pressure is required while still maintaining stable low-pressure regulation.

Silver Spring (S02B) — 14” W.C. to 1 PSIG

Well suited for commercial equipment and light industrial gas pressure control applications.

Yellow/Black Spring (S02C) — 26” W.C. to 1.5 PSIG

Designed for specialty gas trains and systems requiring elevated outlet pressure ranges.

Yellow Spring (S02D) — 1 PSIG to 3 PSIG

Common in industrial burner systems and higher pressure downstream applications.

White High Pressure Spring (S0204E) — 2 PSIG to 5 PSIG

Used for higher pressure industrial regulator configurations where greater outlet pressure control is required.

NGR Regulator Spring Adjustment Tool (NGR-SPTOOL)

The NGR-SPTOOL is the dedicated spring adjustment tool designed for Norgas NGR Series regulators, including the NGR02. This tool allows safe and controlled adjustment of the regulator spring setpoint without damaging the adjustment mechanism.

Built specifically for NGR regulators, it provides a proper fit on the spring adjustment assembly, helping technicians make accurate outlet pressure adjustments during commissioning, maintenance, or spring replacement.

Product Details:
• Model: NGR-SPTOOL
• Application: NGR Series Regulators (NGR02, NGR04, NGR06, NGR08)
• Function: Spring setpoint adjustment

Why It Matters:
When replacing a regulator spring, outlet pressure must be re-set and verified using a manometer or gauge. The correct adjustment tool ensures the spring is tensioned properly and prevents stripping or improper adjustment that can occur when using generic tools.

Recommended Use:
This tool is commonly used by gas technicians, contractors, and service personnel performing spring changes, regulator servicing, or outlet pressure calibration on NGR regulators.

Optional Add-On:
The NGR-SPTOOL can be added to your spring order so you have the correct tool on hand when installing or adjusting your replacement spring.

Designed Specifically for the NGR02 Gas Pressure Regulator

These springs are engineered for direct compatibility with the NGR02 Gas Pressure Regulator, helping ensure accurate outlet pressure, low lock-up, and consistent performance across varying flow conditions.

Using the correct spring range helps prevent improper pressure settings, regulator instability, and unnecessary wear on internal components.

Easy Service & Field Replacement

Spring replacement is a standard service procedure when adjusting outlet pressure ranges, rebuilding regulators, or configuring a regulator for a new application. Keeping the correct spring on hand allows technicians to make fast adjustments without replacing the entire regulator.

Stocking & Availability

We stock multiple NGR02 spring ranges for immediate shipment, including additional inventory of the Orange (2”–7” W.C.) spring due to its high demand in commercial gas applications.

Bulk quantities are available for contractors, OEM skid builders, utilities, and service companies.

Technical Support From a Real Stocking Distributor

We regularly support contractors, utilities, and industrial customers throughout Ohio, Pennsylvania, and New York with regulator selection, spring sizing, and application guidance. If you are unsure which spring range matches your setup, we are happy to help confirm compatibility before ordering.
