Air Regulator, 1/4" FPT, 3-Port #0596AF

Universal Regulator: 3-port, two 1/4" FPT ports, and one 1/8" FPT ports (gauges sold separately here). The regulator controls the amount of air to your air compressor hose. Replace this if you're not able to adjust the PSI to your hose or if it leaks.  

NOTE: If replacing this on older Craftsman "919" model air compressors in which two gauges are installed on the Regulator, only one of the air pressure guages will work with this regulator; modification may be required (see Extra Details below).
