A pump-service kit for backpack sprayers

The Chapin International 6-8180 Piston Pump Repair Kit is made for compatible backpack sprayers that use a piston pump service routine. It gives the sprayer shelf a dedicated repair pack with a visible part number.

Backpack sprayers often live near gloves, funnels, screened strainers, labels, and cleanup brushes. This kit fits that same shelf habit because it is small, easy to label, and tied to a specific service job.

Service work starts with compatibility

The first step is matching the kit to the sprayer. Keep the sprayer’s model information with the kit so the refill is not separated from the tool it supports.

Open the sprayer only after pressure has been released according to the sprayer instructions. A shallow tray gives the piston parts, seals, and package note a safe place while the repair area stays tidy.

Good match

This kit fits gardeners who maintain compatible Chapin backpack sprayers and want a named piston pump repair pack in the service bin.

What to know

Confirm the model fit before ordering. Keep the package, sprayer note, and any removed parts together until the sprayer has been reassembled and rinsed.
