Frequently Asked Questions

Check your sprayer’s parts manual and confirm the exact OEM number 102982 at the referenced location (pump/manifold/gun assembly). If your manual lists a different O-ring size or part #, order that instead.

Loss of pressure, visible seepage at the sealed joint, pulsing spray pattern, or difficulty priming can indicate a worn or damaged O-ring. Inspect the groove and adjacent packings/seats for wear at the same time.

Use only the OEM-specified size and material. If your model calls for 102982, use this exact part. Substitutions can lead to leaks or premature wear.

Clean the groove, lightly lubricate the O-ring, and avoid twisting during insertion. Re-torque hardware to spec and perform a leak/pressure test before spraying coatings.

Compatibility varies by exact model. Check the Magnum’s parts list for 102982. If it’s not listed, use the exact part number specified for that model.
