MP Pumps 21248 Annular Gasket
This gasket seals a joint in the pump housing or wet end against leakage. Gaskets should be replaced any time the joint they seal is opened, since a reused gasket rarely seals as reliably the second time.
Always match by the MP Pumps part number 21248 listed on your equipment parts diagram, since dimensions and material vary across the MP Pumps lineup even for parts with the same common name.

Frequently Asked Questions
Q: What causes this part to wear out?
Wetted components wear from normal operation, cavitation, dry running, or abrasive material in the pumped fluid. Regular inspection catches wear before it causes a bigger failure.
Q: Should I replace other parts at the same time?
When servicing a pump wet end, it is common practice to also replace the mechanical seal, gaskets, and O-rings at the same time to avoid a repeat teardown.
Q: What tools do I need to install this?
Most MP Pumps wet-end parts install with standard hand tools. Always relieve system pressure and disconnect power before servicing a pump.
Q: Can I use this part on a different MP Pumps model?
Wet-end parts are sized to a specific pump model and configuration. Confirm against your pump nameplate before ordering, or send us a picture and we will verify.
