Frequently Asked Questions

Check your sprayer’s model: if it’s an UltraMAX Cordless, TC Pro PLUS Cordless, or Ultimate MX Cordless (models listed above), it typically uses 17P187. Also confirm in the manual/parts diagram for your exact model number.

Both are Triax drop-in pumps, but they fit different handheld families. 17P187 is commonly used on MAX/PLUS solvent-capable cordless models, while 17P186 is typically used on water-based-only Ultra Cordless units. Always match the pump to your exact model number.

No special tools are required. The ProConnect design lets you remove and replace the module with basic steps: power off, relieve pressure, remove old pump, seat the new pump straight in, and prime before spraying.

Difficulty building pressure, pulsation in the spray pattern, fluid leaking past seals, or reduced performance even with clean filters and good batteries typically signal pump wear. A drop-in replacement like 17P187 restores performance quickly.

No. The pump supports “full tip support” within the sprayer’s original rating. Tip size and max pressure are limited by the sprayer model and should not be exceeded.
