Frequently Asked Questions
Match the part number in your sprayer’s exploded parts diagram or service manual. If 166198 is listed for your head assembly, it is the correct replacement. If your manual lists a different tube, use that exact number.
It’s best practice to inspect all related o-rings and seats. Replace any worn seals to maintain proper head sealing and consistent flow after installation.
Non-OEM parts may not match dimensions or materials, which can cause leaks or premature wear. For critical head components, OEM is strongly recommended.
