Milton Industries 1093-4 1/4" FNPT Inline Brass Check Valve 250 PSI

The Milton Industries 1093-4 is a 1/4" FNPT inline check valve engineered for compressed air piping systems. Built with a cast brass body, stainless steel spring, and Teflon poppet, this valve prevents bleed-back of pressure and material into the air supply line while supporting up to 250 PSI and 12 SCFM flow rate.

Key Features:

• 1/4" FNPT connections on both ends for direct integration into standard air line piping
• Cast brass construction with stainless steel spring and Teflon poppet for corrosion resistance and long service life
• 250 PSI maximum operating pressure and 12 SCFM flow rate
• Low 3 PSI cracking pressure — valve opens with minimal upstream pressure
• 450°F maximum operating temperature for high-heat industrial environments
• 1/8" plugged gauge tap included for easy installation of a pressure gauge or pressure switch
• Compact 1-3/4" overall length for tight installations
• Made in the USA

Ideal for air compressor systems, pneumatic tools, and industrial air line plumbing, the 1093-4 installs inline to stop reverse airflow and maintain downstream pressure when the compressor cycles off. The integrated 1/8" gauge port adds monitoring flexibility without requiring additional fittings.
