Graco 15D252 O-Ring Packing

Graco 15D252 O‑Ring Packing

The Graco 15D252 O‑Ring Packing is a key sealing component designed for fluid and hydraulic systems within Graco equipment. Engineered as a precision‑fit sealing element, it helps maintain system integrity by preventing leaks at critical interfaces.

Key Features

• OEM‑specified O‑ring packing for reliable sealing performance
• Manufactured from durable elastomer material that resists fluid degradation
• Compact design ensures a tight fit in pump, valve or fluid‑path assemblies
• Designed for high‑pressure spray systems to prevent leakage under load
• Low‑maintenance part — quick to replace and helps minimise downtime

Technical Specifications

Function & Application

The 15D252 O‑Ring Packing serves as a sealing ring that sits at critical fluid junctions—such as valve seats, pump housings or fluid couplings—where high‑pressure paint, coating or chemical fluids pass through. By forming a tight barrier between mating surfaces, it ensures system efficiency, prevents leaks, and helps maintain consistent pressure.

Installation & Maintenance

• Always ensure that the sealing groove and mating surfaces are clean before installation.
• Verify the correct size and material of the O‑ring to match the service environment.
• Lubricate the O‑ring lightly if required by the system specification to ease installation and avoid damage.
• Inspect periodically for signs of wear such as flattening, cuts or swelling—replace when compromised.
• Using the correct OEM part ensures compatibility with the system’s pressure rating and fluid type.
