insulated water heater t and P relief valves?

[edwardh1]

Do you ever see insulation on the t and P relief valve , not on the discharge line from the valve, but on the standard side screw in valve body itself? ? on a tank, electric, heater? not factory installed insulation?

Some forum folks say water heaters come with a foam like cover (like an outside faucet cover) to fit over the valve. These valves are usually warm to the touch although touchable, and really stand out in my opinion as a heat loss area, especially on a heater build to the new Post march 2015 energy standard.

Cant find anything on the net, except one link to a man that tried to sell them, but that was in the past.

Yes, they all come with that foam sleeve. The last dozen I've bought all had the little foam sleeve.
