This Custom Poppet is a precision-machined stainless steel component designed for fluid-control and motion-control systems. Manufactured from CRES 17-4PH per ASTM A564, the poppet offers high strength and excellent corrosion resistance. With a diameter of 0.6 inches and a total length of 4.1 inches, this Custom Poppet is suitable for compact assemblies that require stable and repeatable actuation.

The Custom Poppet is produced through high-accuracy CNC machining with all surfaces controlled to a 32 micro-inch finish. Burrs are fully removed, and all edges are broken to 0.009 ± 0.006 inches to prevent damage to mating components. Machined fillet radii are maintained at 0.0125 ± 0.0075 inches, ensuring proper stress distribution. These machining details help the Custom Poppet achieve reliable long-term performance.

All diameter features located on the common axis maintain runout within 0.010 inches, ensuring alignment consistency during operation. Angular features meet a tolerance of ±0°30'. This level of accuracy makes the Custom Poppet suitable for precision valve assemblies and mechanical devices requiring tight geometric control.

To improve corrosion protection, the Custom Poppet undergoes passivation per ASTM A967. This finishing process stabilizes the stainless steel surface and enhances durability, making the component reliable for demanding industrial environments.
