Graco 331026 Seat .25 Ball .375 OD TC

Compatible Machines

The Graco 331026 Seat .25 Ball .375 OD TC is an OEM replacement component used across multiple Graco fluid-handling assemblies. Graco does not publish a single fixed compatibility list for this part, as it is installed within specific valve and fluid-section assemblies rather than being tied to one standalone machine.

• Graco industrial fluid section assemblies using a 0.25" ball
• Graco check valve and ball valve assemblies
• Selected Graco pump fluid sections (airless and industrial)
• Graco dispense and circulation systems requiring a .375" OD ball seat

Important: Compatibility depends on the exact machine model and manufacture date. Always confirm the part number against your equipment’s exploded parts diagram before ordering.

Product Description

The Graco 331026 Seat .25 Ball .375 OD TC is a precision-machined OEM seat designed to work with a 0.25" check ball. It provides a reliable sealing surface inside Graco valve and fluid assemblies, helping maintain consistent pressure, prevent backflow, and reduce internal leakage.

This seat is a wear component and should be replaced during routine maintenance whenever sealing performance declines or leakage is observed.
