Ashcroft 45-1009-A-02B-60 is a 4-1/2-inch general-service pressure gauge from the 1009 family, delivering a 0–60 psi range for low-pressure monitoring. The device uses a back-mounted 1/4" NPT male process connection (02B) and is built with a stainless steel case, with the "A" code indicating a phosphor bronze tube and brass process connection rated up to 1,000 psi. This configuration—4-1/2" dial (45), model 1009, back connection (B) and 60-psi range—fits common instrumentation, hydraulic, and process-system applications where accurate, mechanical pressure indication is required.
