Graco 15B254 Front Cover – Product Details & Compatibility
Compatible Machines
The Graco 15B254 Front Cover is used in various Graco airless sprayers, pump assemblies, and fluid‑control modules where a strong, protective front housing is needed.
- Graco high‑pressure airless spray pumps and coating systems
- Graco fluid manifold assemblies that require a sealed front interface
- Graco industrial sprayers where the front cover protects internal components from debris and mechanical stress
Product Overview
The Graco 15B254 Front Cover is a rugged, OEM-grade component that forms the front boundary of Graco pump housings or manifolds. Designed to withstand high pressures and repeated cycling, it protects internal components—like pistons or plungers—from damage, while providing a reliable surface for mounting seals and O‑rings. Its precision‑machined geometry helps maintain alignment of the internal moving parts, improves volumetric stability, and minimizes turbulence or dead volume in the fluid path.
Key Features
- OEM front cover for accurate alignment and sealing in Graco systems
- Durable construction resists abrasion, pressure cycling, and fluid wear
- Built-in O-ring groove ensures tight sealing and prevents leakage
- Optimized port geometry reduces flow turbulence and enhances performance

Usage Notes
- Depressurize the system completely before removing or installing the front cover.
- Use the OEM Graco part 15B254 to maintain system integrity—it’s engineered for precise fit and sealing.
- Inspect the sealing face and O-ring groove for wear, damage or debris before installation.
- Torque mounting bolts in a cross or star pattern to ensure even compression, then check for leaks under pressure.
Frequently Asked Questions
It serves as the protective front housing for Graco pumps or manifolds, safeguarding internal components and maintaining a reliable seal under pressure.
While other covers might fit, using the OEM Graco 15B254 ensures correct dimensions, sealing geometry, and long-term durability.
Replace it if you detect cracks, worn sealing surfaces, or persistent leakage—even after re‑sealing with new O‑rings.
