PowrLiner part 700-926 is a Piston Lube used to lubricate the piston and cylinder assembly in fluid pumps. When lubrication is insufficient or the lube is contaminated, piston wear increases and seal life decreases. This replacement lubricant restores proper piston protection and pump efficiency on compatible PowrLiner, PowerBeast, Performer, Impact, Hydra, Epic, Elite, Airless Sprayer, and other units.

The PowrLiner 700-926 Piston Lube is a specialized lubricant designed to reduce friction between the piston and cylinder wall in fluid pumps, extending component life and maintaining pump efficiency. On compatible equipment including the PowrLiner 3100, PowerBeast, Power Beast, Performer 640 i Airless Sprayer, Impact 1640, 540 Airless Sprayer operation, 440 service, 440 operation, 410, 400 Airless Sprayer, 340, hydrax 4540-7230, Hydra M and Hydra Epic, 660ex, Pro 2000_4000, Hydr M and Hydra Pro Super, Epic 1200 HPG, 690 HPG, 660HPX, 447HPX, 447ex, Elite G40, E55, E15, 3000, 2000, Airless Sprayer1200 GXC, 0537810I_GB_D_F (1), 0528925N_2000_4000, 1100 XC, 690 GXC, 660 XC, 550 XC, 440 XC Airless_Sprayer, and 330 Airless Sprayer, proper piston lubrication is critical for preventing scoring, reducing heat generation, and ensuring smooth pump operation. Without adequate lubrication, the piston can gall against the cylinder wall, causing rapid wear, loss of pressure, and eventual pump failure. Contaminated or degraded lube loses its film strength and protective properties. Replacing old or contaminated piston lube restores proper film strength, reduces operating temperature, and extends the service life of pistons, packings, and cylinders. This genuine PowrLiner replacement lubricant meets original equipment specifications for viscosity, film strength, temperature range, and compatibility with pump materials. When applying piston lube, follow the equipment manual's recommended quantity and interval. Do not over-lubricate, as excess lube can contaminate coating material. Users should always verify compatibility with their specific model and revision before use. Regular piston lube inspection and replacement should be part of preventive maintenance programs for professional spray equipment.
| Friction reduction | Minimizes contact friction between piston and cylinder |
|---|---|
| Wear protection | Prevents scoring, galling, and premature piston failure |
| Heat dissipation |
| Contaminated lube | Lube appears dark, gritty, or mixed with coating material |
|---|---|
| Increased pump heat | Pump runs hotter than normal during operation |
| Pressure loss | Reduced output pressure not caused by other components |
| Scheduled maintenance | Per manufacturer recommended service interval |

Pump performance problems are often caused by more than one component. When servicing the piston lube, these parts are commonly inspected at the same time.
Inspect for scoring, galling, or excessive wear when changing lube.
Worn packings can allow material to contaminate the piston lube.
Damaged fittings or clogged passages prevent proper lube delivery.
