22/410 Treatment Pump Straight Sided 2 Piece Black

For a production-intent package, the 22/410 Treatment Pump Straight Sided 2 Piece Black (Part 127080) offers a defined treatment pump rather than a generic starting point. The 22/410 designation should be verified dimensionally because nominal finish names do not guarantee identical sealing behavior. Its application range extends to serums, facial concentrates, scalp care, and targeted treatments. Test the actual formula for output, priming, leakage, actuation feel, and distribution durability.
