You've been around long enough so if you thought a coating of silicone grease was needed, it probably was and I think it would definitely work. | |

If there is old sealant there, then that indicates that there might have been a problem with this joint in the past. | |

You see this all the time where instructions don't match the item being installed. My old valve had a larger nut with big tab on it, a big wing nut, and I still needed a wrench. just tighten enough to stop any leaking | |

| Oct 3, 2021 at 14:26 | comment | added | Clarus Dignus | Will the plastic back nut eventually crack if I overtighten it? To seal, I seem to have to tighten the nut with a wrench about 720° beyond what my hand's capable of. | |
