Graco 101354 Pin – Precision Dowel Pin for Airless Sprayer Connections

The Graco 101354 Pin is a high-quality, hardened steel dowel pin designed to maintain accurate alignment and support shear loads in Graco airless sprayer assemblies. Installed in critical areas like fluid-end housings and manifold blocks, it ensures precise part registration and prevents misalignment under pressure.

Where It Fits & What It’s Used For

• Fits: Alignment holes in Graco fluid-end modules, pump heads, manifold blocks, and bracket mounting locations where dowel pins are required to maintain mechanical alignment during assembly or service.
• Used for: Locating components during rebuilds, transferring shear load between mating parts, and ensuring accurate sealing surface alignment under high-pressure cycling.

Key Benefits

• Precision fit: Tight tolerances ensure consistent alignment of fluid components, preserving seal integrity and reducing wear.
• Hardened steel construction: Withstands continuous pressure pulsation and mechanical stress common in pro spray applications.
• OEM compatibility: Designed to the factory specification no guesswork during installation.
• Simple to install: Insert during assembly or rebuild to ensure correct component orientation and robust alignment.

Typical Use Cases

• Aligning fluid-end plates, valve seats, and packings during a pump rebuild.
• Indexing manifold halves and accessory blocks to avoid rotational drift under pressure.
• Maintaining bracket orientation on carts or handle assemblies under dynamic loading.

Installation Tips

• Clean pin bore and pin before insertion. Use light oil for smooth seating if needed.
• Press-fit or tap gently until flush with the surface. Avoid damage to mating parts.
• Check orientation during reassembly to ensure proper alignment of fluid or structural parts.

This dowel pin plays a behind-the-scenes but crucial role working closely with your graco paint sprayer filters, graco paint sprayer hoses, and other graco paint sprayer gun parts to maintain assembly accuracy, minimize seal stress, and preserve the performance you rely on.
