Frequently Asked Questions
No — compatibility depends on geometry, mounting, and seal interface. Always check your machine’s parts breakdown and serial number to confirm part 157944 is correct.
Ensure the existing housing is correct, remove fluid and pressure, verify mounting surfaces and seals, and perform a post-installation test for proper flow and operation.
Only if your machine’s parts breakdown shows identical housing dimensions, bolt pattern, and interface. Using it without confirmation may cause leaks or damage. Contact a Graco distributor for verification.
