If I did it with these again, and I may, I would just put a box over the terminals, and also put a male 20-30A receptacle in the box, that way, it is protected, and has quick disconnect.. The box may require thought and fab work, but as far as sealing, I have not noticed a drop in 7-8 years... more than I can say for 1" water heater elements, mainly due to there not being a good supply of stainless 1" NPS half-couplers, the locknuts out there just not thick enough to resist distortion while welding, in my opinion..
