Graco 15A182 Diaphragm – OEM Regulator Seal
The Graco 15A182 Diaphragm is a flexible, high‑quality OEM membrane designed for use in Graco pneumatic regulators. It ensures reliable sealing to maintain accurate pressure control and protect internal components from fluid or air leaks.
Product Overview
This diaphragm is specifically engineered to withstand repeated flexing and high‑cycle operation. Installed within the regulator housing, it creates a tight seal that resists fatigue and stretching over time, helping sustain stable regulator performance. As a genuine Graco part, the 15A182 maintains precision fit and durability under demanding conditions.
