Watts ET90 Expansion Tank

Hi I'm looking to replace my home heating system expansion tank that is leaking. The leaking tank make is EX-TROL. The bottom ring has "30" at the top and pressure tested 150 psi. The measurements are 12.5" tall and 11" wide. It appears the connector is 3/4 inch. Would the Watts ET90 Expansion Tank be the right replacement for my old unit? And can you verify that the pipe is 3/4 inch?

Pre-Charged Non-Potable Water Expansion Tank is rated 3.0 out of 5 by 2.
Rated 5 out of 5 by from Simple swap. I found out the hard way that this was not covered under public service boiler warranty. They wanted to charge a couple hundred to swap this part out. A trip to Home Depot and 20 minutes time and my boiler was back in service. worked perfect.

Rated 1 out of 5 by from Bad as in NOT Good The crimped seam on this in vulnerable to leakage. The seam on mine ruptured and flooded my heat room and basement below it. Get an expansion tank with a welded seam not a crimped seam. This thing caused considerable damage and expense.
