Frequently Asked Questions

Any compatible airless sprayer that supports up to 3600 psi and uses a 1/4" NPSM hose - commonly the Ultra, Ultra Max II, 695/795/1095/1595, GMAX II, DutyMax GH, and Mark HD series. Check your hose thread and pressure rating before use.

It uses the RAC X tip platform and includes a RAC X 517 SwitchTip and guard. You can choose other RAC X tip sizes to match your coating and desired flow/fan.

Yes. Maximum working pressure is 3600 psi. Do not exceed this rating.

In most cases yes—if your sprayer/hose matches the 1/4" NPSM inlet and operates within the 3600 psi rating. Many users upgrade to the latest Contractor-series guns or to Contractor PC; connection and pressure remain the key checks.

Flush promptly after use, keep the tip/guard clean, inspect filters regularly, and store with trigger lock engaged. Replace wear parts (seals/needle) when performance declines.
