Airless Sprayer / Elite / Epic part 761-117 is a piston rod designed to transmit reciprocating motion from the drive to the pumping mechanism on compatible sprayer models. This precision component connects the drive to the piston, converting rotational motion into the linear motion needed for pumping. Replacing a worn, bent, or damaged piston rod restores proper pump operation and ensures reliable performance.

The 761-117 Piston Rod is a critical drive component that transmits reciprocating motion from the sprayer's drive system to the pumping mechanism on compatible Airless Sprayer, Elite, and Epic models. It connects the crankshaft or drive to the piston, converting rotational motion into the linear motion needed to create pumping action.
The piston rod must withstand significant alternating stresses during operation while maintaining precise alignment with the pump cylinder. It includes the rod itself along with any attached bearings, bushings, or connection hardware necessary for proper function. Over time, piston rods can become bent from overloading or impact, worn at bearing surfaces, or develop fatigue cracks from repeated cycling. A worn or damaged piston rod can cause misalignment, increased friction, reduced pump output, and accelerated wear of seals and cylinder walls. Replacing the piston rod restores proper drive-to-pump connection, ensuring smooth operation and consistent pumping performance.
| Motion transmission | Transfers drive motion to the pumping piston |
|---|---|
| Force transfer | Transmits pumping force from drive to fluid |
| Component connection | Links drive system to pump mechanism |
| Bent / deformed | Rod is no longer straight, causing misalignment |
|---|---|
| Worn bearings | Excessive play at connection points |
| Cracks / fatigue | Visible cracks indicating potential failure |
| Reduced pump output | Loss of pressure or flow due to drive issues |
Part 761-117 is compatible with the following sprayer models. Always verify fitment using your equipment's parts diagram before ordering.
| Model | Component |
|---|---|
| Airless Sprayer 1200 GXC | Piston Rod |
| Elite E20 | Piston Rod |
| Epic 1200 HPG | Piston Rod |
When replacing the piston rod, these associated components are often inspected or replaced at the same time.
Seals that ride on the piston; inspect and replace if worn.
The drive component that connects to the piston rod; check for wear.
Bearings at rod connection points; replace if worn.
