Frequently Asked Questions

Part 109304 is the throat V‑packing (lips face down), while 109305 is the piston V‑packing (lips face up). Both are PTFE and used in the displacement pump packing stack.

No, they are not interchangeable. 109305 is designed specifically for the piston stack, and 109304 is for the throat stack.

Some displacement pumps support alternative packing materials like leather or UHMWPE. Always check your pump's service manual and optional kit numbers for compatibility.
