This 10" vented threaded tank lid from Norwesco (part number 67398) is a common replacement when an original cap has cracked, warped, or gone missing. It's a threaded design, so it spins down snug instead of relying on a friction fit, and the vented construction lets your tank breathe as liquid levels change during filling and draining. The threaded ring is included — helpful, because on many tanks the old ring is just as weathered as the lid itself, and replacing both at once gives you a clean, matched fit.
Getting the Right Fit
Lid sizing trips people up more than any other accessory. Measure your existing lid or opening, and match the 10" size and thread style to your tank before ordering. If you're not sure what your tank takes, call us at 866-418-1777 and we'll confirm fit for your tank before you buy.
