Can these be waterbathed or Steam Bathed to preserve my BBQ Sauce?
These 38‑400 metal closures are not recommended for water bath or steam canning. Metal CT caps with standard plastisol liners are designed for hot fill, but they are not intended to withstand the sustained high heat and steam pressure of canning processes, which can compromise the seal. For preserving BBQ sauce, we recommend using canning‑rated jars and closures specifically designed for water bath processing.
