CHECK VALVE - New In Tank Air Compressor 3/4-inch FPT x 3/4-inch MPT | USA Made

Reliable one-way flow for your air system

Introducing the CHECK VALVE designed to protect and optimize air compressors by promoting one-way air flow from the unit toward the tank while preventing reverse flow. This in-tank valve is built to endure demanding workshop conditions and is proudly made in the USA, providing a dependable component for many setups.

Key benefits at a glance

• One-way air flow helps maintain steady pressure and reduces backflow risks.
• Made in the USA with sturdy construction for long service life in hot and high-demand environments.
• Rated up to 450 PSI and 400 F, making it compatible with a wide range of standard compressors.
• Top connection and outlet both use 3/4-inch NPT threads for straightforward integration and a clean install.
• Includes a 1/8-inch unloader port for optional pressure relief or system signaling.
• 30 SCFM flow capacity supports efficient air delivery during peak use.

Real-world use and setup

In a home workshop, this valve can help maintain tank pressure between cycles, contributing to smoother starts and fewer fluctuations. The compact 3/4-inch NPT connections simplify attachment to typical compressor lines and tanks, reducing clutter and potential leak points.

Users often appreciate the immediate, reliable action of a one-way check valve in preventing backflow, which can extend the life of other components and protect system integrity in busy environments.
