Flame King Propane Tank Gauge — Solid Brass 2-Pack, Color-Coded Glow-in-the-Dark Level Indicator

The Flame King Propane Tank Gauge is a universal, solid-brass cylinder level indicator with a glow-in-the-dark, color-coded dial and an integrated excess flow shutoff for safer, more reliable propane monitoring.

Keep your grills, heaters, and camping appliances fueled and safe with a compact gauge that fits standard propane cylinders. This Flame King 2-pack attaches to the tank valve to show remaining fuel at a glance, using an easy-to-read color system and luminous markings for low-light conditions. Built from solid brass and tested to recognized UL, ANSI Z21.18, and CSA 6.25 standards, it combines durability with an automatic safety cutoff that helps halt fuel flow in sudden pressure events.

How does this gauge tell me when propane is low?

The meter displays tank pressure on a color-coded dial so you can instantly know if levels are full, in the caution zone, or nearly empty. The luminous paint on the dial makes reading the gauge possible at night or in dim settings. This gives you time to swap or refill cylinders before your appliance stops working.

• Color-coded face shows green (good), yellow (low), red (replace)
• Glow-in-the-dark markings for nighttime visibility
• Pressure-sensing mechanism calibrated for common cylinder sizes

Will this fit my propane cylinder and appliances?

The Flame King gauge is designed as a universal quick-attach for most standard LP cylinders used with grills, patio heaters, and RV lines. It screws onto the tank’s POL or standard threaded outlet depending on the model and seating, providing a secure connection. Check your tank valve type to confirm compatibility before purchase.

• Compatible with the majority of standard propane cylinders
• Simple thread-on installation — no tools in many cases
• Compact profile keeps the gauge out of the way while in use

What safety features does the gauge include?

This Flame King meter includes an integrated excess flow check valve that automatically stops fuel flow if a sudden surge or line break occurs, reducing risk of uncontrolled gas release. The solid-brass body resists corrosion and damage from outdoor exposure, and the unit meets industry safety benchmarks. Together these elements improve reliability and help protect your equipment and surroundings.

• Excess flow shutoff to halt gas during sudden pressure anomalies
• Solid brass construction for weather resistance and durability
• Tested to UL, ANSI Z21.18, and CSA 6.25 safety standards

How durable and reliable is the construction?

Manufactured from heavy-duty solid brass, the gauge withstands outdoor use and resists rust, ensuring long service life even in varied climates. The mechanical pressure element is built to give consistent readings over many cycles. The 2-pack provides a spare or a matched set for multiple cylinders, simplifying propane management for households or outdoor setups.

• Solid brass body for long-term outdoor durability
• Mechanically tested to relevant compliance standards
• Sold in a 2-pack to cover more than one tank or as a backup
