Aircoat part 0533413 is a piston stud that connects the piston to the drive rod or connecting components in the pump assembly of compatible sprayers. This precision-machined threaded stud provides a secure attachment point, ensuring positive transmission of reciprocating motion from the drive to the piston. It is an essential structural component during pump rebuilds on Aircoat 423 models.

The Aircoat 0533413 piston stud is a precision threaded fastener that connects the piston to the drive rod or connecting linkage in the pump assembly. It transmits the reciprocating force from the drive system to the piston, creating the pumping action that draws and pressurizes paint.
Piston studs are subjected to significant cyclic loads and stress. Over time, threads can strip, the stud can bend, or it can fatigue and break. A damaged stud can cause loss of piston motion, misalignment, or complete pump failure. Replacing the piston stud during major pump overhauls ensures secure attachment and reliable power transmission.
| Connects piston to drive | Links the piston to the drive rod or connecting components |
|---|---|
| Transmits motion | Transfers reciprocating force to create pumping action |
| Provides secure attachment | Threaded design ensures positive mechanical connection |
| Maintains alignment | Positions piston correctly relative to drive system |
| Stripped threads | Damaged threads prevent secure fastening |
|---|---|
| Bent or warped stud | Distortion causes misalignment and binding |
| Visible wear or corrosion | Pitting or wear compromises strength |
| During major overhaul | Replace preventatively when rebuilding pump |
Aircoat part 0533413 is designed specifically for use with the following sprayer model. Always verify your pump configuration before ordering.
