Review: Did the job - Just what was needed and took care of the issue Review: Fits old Thetford toilet easy replace. - My toilet was smelling bad and figured it was the flange seal. My old one was worn out and distorted allowing gases front black tank to seep into the camper. These are super easy to replace so don’t feel intimidated not a dirty job. 1. Turn off the water and pump to your rig 2. Turn on few faucets to relieve the pressure in the lines 3. Hold the foot pedal down for a few seconds to dump all the water 4. Remove front cover around foot pedal “it just snaps on” 5. Unscrew water line on back of toilet mine just threads on by hand no tools needed. (Recommend getting a towel around water line, little excess water in the line will probably drip out. It’s clean water don’t worry comes from same place your sink does) 6. On each side of the toilet these is a nut you need to remove I think was 9/16 I just used adjustable wrench. 7. After removing nuts and disconnecting water line your toilet can be lifted off. I laid down a trash bag on the floor to set it on. 8. Replace gasket, old one will be either stuck to floor flange or on bottom of the toilet. Place the new one on the bottom of the toilet with the tapered part facing down towards the floor. 9. Set toilet back in place will be little tricky to line up the holes for the bolts. Ensure the toilet is centered on the hole and sits flush and straight. 10. Tighten down the two nuts. Don’t over tighten them, the flange and the toilet is plastic and will crack. Just snug is good. 11. Reconnect water line and turn water back on and your done. No more sewer smell. ## Features - Closet flange for Thetford toilets.Fit Type: Universal Fit - Replaces 02125 - Current part number 33239 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BGM7QS | | Best Sellers Rank | #36,153 in Automotive ( See Top 100 in Automotive ) #37 in RV Toilet Spare Parts | | Brand | Thetford | | Brand Name | Thetford | | Color | Gray | | Customer Reviews | 4.6 out of 5 stars 3,373 Reviews | | Global Trade Identification Number | 00028985332398 | | Included Components | 1 - Closet Flange Seal | | Item Type Name | Replacement Closet Flange Seal for Electra Magic Model 80, Aqua-Magic, Starlite, and Galaxy RV toilets Thetford-33239 | | Manufacturer | Thetford | | Manufacturer Part Number | 33239 | | Manufacturer Warranty Description | 1 year limited warranty: part coverage for repair or replacement of defective parts. | | Material | Plastic, Rubber | | Material Type | Plastic, Rubber | | Model Number | 33239 | | Number of Items | 1 | | Number of Packs | 1 | | Recommended Uses For Product | sealing RV toilet connections, preventing water leakage in RV toilets, maintaining a watertight seal in RV toilet systems Recommended Uses For Product sealing RV toilet connections, preventing water leakage in RV toilets, maintaining a watertight seal in RV toilet systems See more | | UPC | 028985332398 | | Unit Count | 1 Count | ## Product Details - **Brand:** Thetford - **Color:** Gray - **Material:** Plastic, Rubber - **Number of Items:** 1 - **UPC:** 028985332398 ## Images ![33239 Closet Flange Seal , Gray - Image 1](https://m.media-amazon.com/images/I/41c0t2T8zqL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Did the job *by M***N on August 19, 2026* Just what was needed and took care of the issue ### ⭐⭐⭐⭐⭐ Fits old Thetford toilet easy replace. *by C***S on April 25, 2025* My toilet was smelling bad and figured it was the flange seal.
