FAQs
Is this part compatible with all Di Martino sprayers?
No, this piston is specifically designed for the Rosy series. Check your manual for the model number IN-EK3-74151.
Do I need special tools to replace the piston?
Generally, no special tools are required, though a pair of pliers may help remove stubborn retaining clips.
How often should I replace the piston?
Replacement is recommended only when you notice a significant drop in pressure or difficulty in pumping the sprayer.
Can I use petroleum jelly to lubricate the piston?
It is best to use a food-grade silicone lubricant, as petroleum-based products can degrade certain rubber seals over time.
Does this package include a new O-ring?
This product contains the spare piston; please check the package contents, as O-rings are often sold separately.
Troubleshooting
Sprayer fails to build pressure after replacement
Ensure the piston is correctly seated and that the pump cylinder is free of internal debris or cracks.
Pumping handle feels stiff
Apply a thin layer of silicone lubricant to the piston seal to improve movement within the pump barrel.

Setup, Compatibility & Care
To install the piston, ensure the sprayer reservoir is completely empty and depressurized. Unscrew the pump handle assembly and carefully remove the existing piston unit. Inspect the chamber for debris before inserting the new IN-EK3-74151 piston. It is recommended to apply a small amount of silicone-based grease to the piston seal before insertion to extend its lifespan. Always store the sprayer in a cool, dry place when not in use to prevent the piston materials from degrading prematurely due to UV light or extreme temperature fluctuations.
