Graco 15A181 Diaphragm – OEM Pneumatic Regulator Seal
The Graco 15A181 Diaphragm is a precision OEM membrane designed to deliver reliable sealing performance in Graco pneumatic pressure regulators. It isolates internal components while allowing smooth, stable pressure regulation through repeated cycles.
Product Overview
Engineered for durability, this diaphragm is built to flex repeatedly under high‑cycle conditions without losing integrity. Installed within the regulator’s diaphragm housing, the 15A181 forms a tight, resilient seal that prevents leaks, helps maintain consistent pressure, and extends the service life of the regulator assembly.
