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

Pros: These are very thick silicone rubber boots that will definitely protect the sensors if dropped. Cons: They are very large. To install them I had to remove the suspension and fold the tall onboard sensor to the side. I understand the gauges are near the start, but I would be willing to sacrifice boot thickness for a better fit.

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.

They barely fit a 41 series 3 1/8" gauge manifold. If you remove the hook you can attach them ( then reattach the hook) but they are pushed together in the middle which makes them sit a bit odd. I believe they should be used with the "Brute" collector. I will continue to use them as they should still work fine. I also find them a bit pricey for what they are.

I use these on a set of 3 YJ standard hose gauges, not the Titan series. They work. A little hard to hit just because the sensors are too close together. Lasts 3 minutes. In fact, they adjust the sensors a little looser than I'd like. Would have preferred something a little tighter and fully closed (in the back). Even if it means removing the sensors for installation. But I bet they will help extend life. At least some. Although they are overpriced for what they are.

I bought these to protect the gauges on the Yellow Jacket A/C hose set I bought. They look very nice and have a good finish. Unfortunately, they are not suitable for pressure gauges, since the pressure gauges on the manifold are too close together and the hanging hook is a nuisance. Even if you remove the hook, they won't fit in the space between the sensors. One can be placed, but there is no room for the second. Too bad they look so pretty and are advertised next to the sensors so it looks…
