Graco 15G838 Suction Drain Cup

Superior Fluid Management with the Graco 15G838 Drain Cup

Product Overview

The Graco 15G838 Drain Cup is engineered for high‑performance fluid control in demanding airless spray systems. Built to integrate seamlessly with major stand‑mounted sprayer rigs, this component ensures reliable suction and drainage cycles while protecting pump performance and reducing downtime.

Key Features

• Precision‑molded suction cup body for secure, leak‑free operation
• Impact‑resistant polymer construction provides durability in professional environments
• Quick‑release tool‑free adapter enables fast installation and servicing
• Integrated high‑pressure filtration interface shields pump and fluid pathways from debris
• Optimized fluid path geometry for efficient drainage and minimal residual fluid

Construction & Materials

The drain cup features a rugged polymer bowl designed to endure heavy‑duty spray operations and resist chemical and solvent attack. Its clear sight‑window allows visual confirmation of fluid clarity, while the sealing system is built on premium elastomer materials to ensure reliable performance across a wide range of coatings and cleaning agents.

Performance & Compatibility

• Built specifically for use with stand‑mounted systems such as the 490 and 495 series Ultra Max II
• Designed verification for high‑flow drainage under pressurized conditions, helping maintain system throughput
• Minimizes downtime by enabling rapid fluid changes and limiting contamination risks during drainage

Installation & Maintenance

The 15G838 is designed for straightforward installation with its standardized thread pattern and clamp flange arrangement. When servicing, technicians should inspect the O‑ring seal for wear or deformation and confirm the clarity of the sight port. The tool‑less release mechanism simplifies bowl removal for cleaning or replacement, and the modular design makes on‑site service quick and efficient.

Why It Matters

In professional spraying applications, fluid control is critical. The Graco 15G838 Drain Cup delivers peace of mind by combining precision engineering with field‑proven durability. It helps protect your sprayer’s pump, maintains consistent pressure through drainage cycles, and supports efficient operations — whether you’re handling specialty finishes, high‑volume coating jobs, or frequent material change‑overs.
