Key Features

- Correct Seating Geometry — as a setting tool component, this collar ensures the mechanical seal is driven to the correct depth and seated squarely, which is critical to achieving a leak-free pump.

The Seal Setting Collar is a precision installation component used when fitting or replacing the mechanical seal inside a WA20 water pump. It guides the seal into its bore at the correct depth and alignment, preventing damage to the seal faces during installation. Without the proper collar, a seal can be cocked or under-seated, leading to premature leakage and pump failure.
