Graco 15A180 Diaphragm – OEM Pneumatic Regulator Seal
The Graco 15A180 Diaphragm is a flexible, high‑quality OEM component designed to provide a reliable sealing surface in Graco pneumatic regulators. It plays a critical role in maintaining accurate pressure control by isolating the regulator’s moving parts from fluid or air leakage.
Product Overview
This diaphragm is built to endure frequent flexing and repeated pressure cycles. Installed within the regulator’s diaphragm housing, it ensures smooth operation by forming a tight and durable seal, helping to resist fatigue, stretching, or deformation over time. As a genuine Graco part, it is engineered for compatibility and long-term performance in Graco pneumatic regulator assemblies.
