Product Details
✓COMPLETE TOILET SEAL KIT: Includes 1x Floor Flange Seal, 1x Flush Ball Seal, 2x Fixing Bolts, 2x Fixing Nuts, 2x Nut Spacers, 2x Bolt Caps. Everything you need for a leak-free repair is in one package. The set takes the place of part numbers 385311652 and 385311658. Please check the size and part number of the old seals before ordering.
✓WIDE COMPATIBILITY: This RV toilet flush ball seal and base gasket set is compatible with 300, 310 and 320 Series RV toilets. Note: Does not fit models 210, 510, or any model not listed here. Compare the old seals with the listing photos before ordering, because seals from other series look close in size but will not swap over.
✓SOLVE LEAKING AND ODOR ISSUES: A new RV toilet floor flange seal and flush ball seal make a tight joint again, so bowl water sits at the right level and tank smells stay down in the tank. Time for new seals when water pools around the base of the toilet, when bowl water drains away between uses, when smells hang around inside, or when the foot pedal feels soft.
✓HIGH-GRADE RUBBER BUILD: Both camper toilet gaskets are molded from a flexible, wear-resistant rubber compound that holds shape after repeated compression cycles and resists drying out, cracking and deforming through summer heat and winter travel. The included bolts, nuts, spacers and caps provide a corrosion-resistant hold, keeping the base joint secure season after season on rough roads.
✓EASY TO INSTALL: This RV toilet repair kit fits in within minutes using basic hand tools. Steps: 1) Shut off the water supply, press the foot pedal and pull out the old gasket. 2) Wipe all debris from the rim and flush ball surface. 3) Apply silicone grease to the bottom and groove of the new seal. 4) Press the seal down with the THIS SIDE UP marking facing up, turn the water back on and check for drips.
✓100% LIFETIME PROTECTION: Enjoy reliable performance with our lifetime protection, ensuring that your product will always be covered for any defects or issues that may arise.
