Power Tank 400 psi Super Flow Regulator Replacement Front Gauge

The Power Tank 400 psi Replacement Front Gauge is a direct-fit service part for any Power Tank Super Flow regulator, restoring accurate tank pressure readings after a gauge breaks or fails. The silicone-filled, 1.5-inch dial threads in via standard 1/8" NPT and is sold individually as a single front gauge.

Built to Match the Original

The replacement gauge is silicone filled, which dampens needle flutter caused by pressure surges and protects the internal mechanism from moisture. That is the same construction used in the original Super Flow regulator gauges. At 1.5 inches in diameter, the dial is large enough to read clearly while working at the tank, and the 1/8" NPT thread is the industry-standard fitting used across Power Tank's Super Flow regulator line regardless of when the regulator was made.

Fits Any Super Flow Regulator, Any Age

Power Tank designed this gauge as a universal direct-fit replacement across the entire Super Flow regulator family. No production-year matching or model-suffix matching is required. If the regulator is a Power Tank Super Flow, this gauge fits. That compatibility span means a single spare can cover multiple regulators in a fleet or shop without stocking separate part numbers.

Rubber Boot Availability

A rubber boot is included on this gauge as stock allows. Boots will not be restocked once current inventory is exhausted, so future orders may ship without a boot. The gauge itself is fully functional without the boot; the boot provides impact protection for the dial housing only.

Features

• 400 psi range: matches the pressure scale of Power Tank Super Flow regulators
• Silicone filled: dampens needle movement and resists moisture intrusion
• 1.5 in. diameter dial: readable at arm's length while working at the tank
• 1/8" NPT threads: standard fitting for direct installation into the regulator body
• Rubber boot: included as stock allows; boots are not being restocked

Specifications

Who This Is For and Isn't

This gauge suits any Power Tank Super Flow regulator owner who needs to replace a cracked, broken, or inaccurate front gauge. It is the correct service part whether the regulator is a recent purchase or a years-old unit, and it works across the full Super Flow line without fitment matching.

This gauge fits Power Tank Super Flow regulators only. It is a front (tank pressure) gauge only and does not replace a downstream or outlet gauge. A rubber boot is not guaranteed to be included.

Common Questions

Which Power Tank regulators does this gauge fit?

The 400 psi replacement front gauge is a direct fit for any Power Tank Super Flow regulator regardless of the year it was made. No model-year matching is required. If the regulator is a Power Tank Super Flow, this gauge installs directly into the front gauge port.

What does "silicone filled" mean and why does it matter?

A silicone-filled gauge has its internal chamber filled with silicone fluid rather than left air-filled. The fluid dampens needle movement caused by pressure spikes, making the reading steadier, and it also protects the internal mechanism from condensation and moisture that can corrode a dry gauge over time.

Will a rubber boot be included with my gauge?

A rubber boot is included on the 400 psi replacement front gauge as stock allows. Boots will not be restocked once current supply is gone, so orders placed after boot inventory is exhausted will ship without one. The gauge operates normally without the boot.

What tools are needed to install this gauge?

The replacement front gauge uses a standard 1/8" NPT thread, which is a tapered pipe thread. Installation requires a wrench sized to the gauge hex fitting and thread sealant appropriate for gas service. No torque value is specified in the product data, so follow the regulator's service documentation for final installation guidance.

Is this a front gauge or an outlet gauge?

This is the front gauge, which reads the pressure remaining in the CO2 tank. It is not an outlet or downstream gauge. If the outlet gauge on a Super Flow regulator needs replacement, a different service part is required.
