Got a Permco pump that needs some hardware replaced, this the cap screw that comes with it?

Question by: Lance P on Feb 25, 2026, 9:36 PM

Permco makes this cap screw specifically for use in their hydraulic systems, and it carries part number W1-400. If your pump or component calls out that number, you're in the right place. It's built to Permco's quality standards, so fitment and reliability should be right in line with what the original setup required.
