Overview

The Marshall CW00015 is a compact, liquid-filled pressure gauge designed for accurate monitoring in the 0–15 PSI range. Its stainless steel case and bezel provide excellent corrosion resistance and durability, making it well suited for automotive fuel pressure monitoring, carbureted engine setups, and other low-pressure applications. The liquid fill dampens needle oscillation caused by vibration and pressure pulsation, allowing you to take quick, reliable readings even while equipment is running.

Featuring a clean white dial face with a high-visibility red pointer, the CW00015 is easy to read despite its compact 1.5-inch diameter. The 1/8" NPT center back connection is a widely used standard, simplifying installation in most fuel lines and manifolds. The included Easy-Vent Nipple Plug allows you to purge trapped air from the gauge case, which is essential for maintaining the accuracy and responsiveness of the liquid-filled mechanism over the life of the gauge.

Frequently Asked Questions

The Marshall CW00015 measures pressure from 0 to 15 PSI, making it suitable for low-pressure fuel systems and similar applications.
The gauge case is filled with liquid (typically glycerin) to dampen needle vibration caused by pulsation or mechanical shock, resulting in steadier, more accurate readings.
The gauge uses a 1/8" NPT center back connection, which is a standard pipe thread fitting widely used in fuel and pressure systems.
The Easy-Vent Nipple Plug allows you to release trapped air from the liquid-filled case, ensuring the gauge provides accurate readings and the needle moves freely.
