Lightly lubricate packings per manufacturer guidance; avoid over-tightening gland nuts.
After reassembly, prime with compatible fluid and check for leaks at low pressure before normal operation.

Frequently Asked Questions

Check your model’s parts manual and verify that the packing kit listed is 256974. If your unit is a FinishPro 290 or FinishPro II 295, this is the documented kit.

Loss of prime, material weeping from the lower pump, inconsistent pressure, or excessive pulsation typically indicate worn packings and seals that should be replaced.

Packing kits include the wear and sealing components for the fluid section. Fasteners, rods, housings, and metal pump components are typically not included unless specified in the bill of materials for 256974.

Yes. Replacing worn seals and packings helps restore proper sealing and smooth pressure delivery, reducing pulsation and leak-related performance loss.

Flush after each use with the correct solvent, avoid running the sprayer dry, strain materials, and follow recommended lubrication practices. Regular maintenance prevents premature packing wear.
