How to Choose the Right Graco Replacement Parts for Graco 395 ST/ST Pro

Verify your exact Graco 395 model variant (ST vs. ST Pro) before ordering to ensure part compatibility.
Confirm pump serial number and hours of operation to determine which repair kit (packing, ball-and-seat, or seal) is needed.
Check pressure rating and flow requirements; some kits fit 390/395/490/495 families; confirm yours matches.
Assess hose assembly specifications: suction vs. drain, material compatibility, and fitting thread size.
Review OEM part numbers on your equipment; counterfeit kits circulate—purchase only authentic Graco components.
Plan maintenance schedule around peak season; stock high-wear items (packing kits, o-ring seals) proactively.
Evaluate warranty and return policy; OEM parts carry manufacturer backing that aftermarket substitutes do not.

Frequently Asked Questions

How often should I replace the pump packing kit on my Graco 395 ST?

Pump packing typically requires replacement every 500–1,000 spray hours, depending on fluid type, pressure, and ambient temperature. Hydraulic fluids wear seals faster than latex or acrylics. If you notice fluid leaking around the pump rod or loss of pressure hold, it's time to replace the Graco 18B260 Pump Packing Repair Kit.

What's the difference between the ball-and-seat kit and the packing kit?

The packing kit (18B260) seals the pump rod and prevents internal leakage. The ball-and-seat kit (246429) is a check valve that allows one-way flow during pressurization. Both wear out independently. Ball-and-seat failure causes pressure loss and backflow; packing failure causes rod sealing leaks. Many rebuild jobs require both kits.

Can I use suction hose kits from other Graco models on my 395?

The Graco 246386 Suction Hose Kit fits 390, 395, 490, 595, and 695 models. However, confirm your exact model and inlet fitting size before ordering. Cross-model compatibility exists but is not universal. Verify part number against your equipment manual or call our technical team to avoid mismatches.

My Graco 395 loses pressure after 10 minutes of spraying—what part should I replace?

Sudden pressure drop typically indicates ball-and-seat valve failure (246429 kit), worn pump packing (18B260), or a blocked drain hose. Start by inspecting the drain hose (246381) for clogs, then test pressure hold with the trigger locked. If pressure bleeds off, the ball-and-seat check valve is likely defective.

Are these OEM parts or aftermarket, and do they carry warranty?

All parts in this collection are authentic Graco OEM components with manufacturer warranty. Counterfeit Graco kits flood the market and fail prematurely. Purchasing from authorized distributors like Pittsburgh Spray Equipment ensures authenticity, warranty coverage, and technical support.
