They almost assuredly don't sell pipe dope at lowes or HD. Its a specialty plumbing product. It's an entirely different product for an entirely different application than plumbers putty. It accomplishes the same goal as Teflon tape, but it seals more threads, and again, as mentioned, it allows a watertight seal with the benefit of easily unscrewing the pipe. Ace sells it for sure, and you can probably find it on Amazon. Also FWIW: I've tried all kinds of different bulkheads and none compare to Spears. They're pricy, but you'll have them for life. Good luck homes
