Review on 👢 Top-rated Yellow Jacket 49190 Boots for 3-1/8" Gauges - Ultimate Protection and Precision by Doug Darling

As other reviewers have said they are really designed for big rough manifolds, on the standard manifold 42001 they are really too big. They are made from a very thick rubber material and you have to remove the hanger and then twist the sensors a bit to put the caps on, not too much work but the material could be thinner and closer to the sensor. I should have checked the reviews better.
