Frequently Asked Questions

Model-specific fitment for Graco 102591 is not listed publicly. Check your machine’s parts manual/diagram for an exact part-number match. If 102591 is called out in the lower/seal assembly, it will fit your unit.

Graco’s public listings do not provide a standalone pressure/material spec for 102591. Use the pressure/chemical limits of your specific pump/housing assembly as the governing specification and follow the service manual.

For best performance and fit, use genuine Graco parts. Aftermarket seals may not match the encased geometry/tolerances and could lead to leaks or premature wear.

Match the exact part number (102591) from your equipment’s exploded diagram or parts list. If your manual shows a different number for the seal module, order that specific part instead.

Use clean, compatible fluids; flush after use per Graco guidelines; avoid dry running; keep filters clean; and store equipment in a clean, temperate environment to prevent seal degradation.
