Product Description

The Graco 15A739 Air Cover SST is a rugged, corrosion-resistant protective housing crafted specifically for the air-motor assembly of Graco’s Husky 1590 stainless‑steel diaphragm pump. Designed to withstand aggressive environments and harsh process fluids, this cover shields the internal air-valve and motor components from damage, maintaining performance and reliability.

Constructed from durable stainless steel (SST), the 15A739 provides superior protection against chemical exposure, moisture, and abrasion. It ensures that the sensitive air-drive components remain isolated from external contaminants, thereby extending the pump’s service life and reducing the risk of premature failure.
