Finding an Eljer toilet tank lid is easiest when you separate three questions: what toilet/tank do you have, what lid number belongs to it, and does the physical replacement match the shape in front of you?
Find every number on the tank and lid
Carefully remove the cover and inspect the inside tank walls. Record the Eljer name, stamped or molded numbers, ink markings and any date information. Turn the original lid over and photograph any number molded into the porcelain.
Do not assume the tank number and lid number will match. Replacement catalogs often need both because an older toilet may be known by a tank number while the porcelain cover carries a separate service part number.
Use verified cross-references
For example, FixALid’s current catalog includes an Eljer 151-0100 lid cross-referenced to the 141-0220 tank family, as well as an Eljer 5540 lid listed for 141-1145. These are separate physical listings; one relationship should never be generalized to an unrelated Eljer model.
Confirm fit with photos and dimensions
Measure overall width and front-to-back depth. Compare the front edge, rear edge, corner radius and taper. Then compare the underside lip, feet and ribs. The underside often reveals differences that are almost invisible in a top-down product photo.
Old Eljer colors can be difficult to name
White, bone, biscuit and older specialty colors can shift in appearance with bathroom lighting and age. Identify the model first. Once the physical part is correct, compare color in natural daylight and use a neutral white object as a reference.
Discontinued Eljer parts
Many older toilets are still perfectly serviceable after factory replacement parts become difficult to find. A used original porcelain lid can preserve the toilet without replacing the entire fixture, provided the exact fit is verified.
Eljer identification checklist
- Record all numbers inside the tank.
- Inspect the underside of the lid for a part number.
- Use model cross-references rather than brand alone.
- Measure and compare underside geometry.
- Confirm color last.
