Frequently Asked Questions
How do I know if I need to replace this seal?
Signs you need a new cooling tube seal include visible leaks around the cooling tube connection point, moisture or residue near the pump housing connection, or loss of pump efficiency. If you're disassembling your pump for any maintenance, it's good practice to replace this seal as preventive maintenance.
Will this seal fit both 250 and 500 series pumps?
Yes, this seal is designed to fit both Dometic 250 and 500 series sanitation pumps. It's the correct OEM seal for the cooling tube connection on both pump series.
Is this seal difficult to install?
Installation requires basic mechanical skills and access to the pump housing. You'll need to disconnect the cooling tube from the pump, remove the old seal, clean the sealing surfaces thoroughly, and install the new seal. Always refer to your pump's service manual for specific instructions.
Should I replace other seals at the same time?
When servicing your Dometic pump, it's recommended to inspect all seals and gaskets. If you're already accessing the cooling tube area, consider replacing other wear items to prevent future leaks and avoid repeated disassembly.
