Plate & Frame Part Numbers
These are real Mueller seven-digit SKUs, and they are the numbers to order against. A gasket is identified by three things: the plate model it fits, the compound, and how it attaches.
Compound. NBR for oils and general duty, EPDM for hot water and steam, EPDM-PW where the water is potable. The compound sets the temperature limit in the table, and it is the single most common cause of a gasket that fails early — the wrong compound does not fail on commissioning day, it fails a season later.
Attachment. Glue-in gaskets are cemented into the groove. Loc-In gaskets clip in without adhesive, which makes a regasket dramatically faster. They are not interchangeable — the groove is different.

Accu-Therm Replacement Gasket Part Numbers
Do Not Re-Use a Gasket
Compression set is invisible. A gasket that looks untouched can have given up most of its spring, and it will seal on the first close and weep as soon as the unit starts cycling. Regasket the whole pack rather than the plates you think leaked.
Count Before You Order
The plate count on the nameplate is what shipped, not necessarily what is in the frame now. Packs get shortened, plates get pulled. Count them while the unit is open, and order to the count.

Common FAQs
No. The groove profile differs. Order to the plate model code in the table.
It depends on temperature, chemistry and how often the unit cycles, far more than on elapsed years. Records of your own service history beat any general figure.
