Convert your 1” drain hole to a standard NPT threaded drain hole.
Seal the adapter in using 3M 5200 sealant and then install the Versiplug so you’ll never forget your plug again.
Comes with adapter and mating Versiplug drain valve.

Other sizes available by request. Let me know what size your hole is and I’ll plug it. 

Feel free to call or text if you have any questions
