HVAC Gauge Boots 49190 Cover for Yellow Jacket JB 3-1/8" HVAC Gauges, AC Gauge Protector Boots 4910 Refrigerant Gauges Manifold Protective Covers (Pack of 2)

Easy to install although you will need to take hook off and install these. They are a little loose but other than that they’re good

They fit a little loose so I put a single layer of gorilla tape on the outside edge of the gauges and they fit perfectly.I'm rebuilding a Titan 4 valve manifold and didn't want to pay $32.00 for a pair of Yellow Jacket brand boots.

As many others have already said, they seem like they were molded too big for the gauges intended. You can see the circles become eccentrics when forced onto gauges, against the hanger. But I expect they will do the job and probably shrink a little over the next couple years in the wash, like everything else i buy.

Exactly what I wanted. Good quality.

Excellent

Not a perfect fit but I think they’ll do the job , maybe they fit better on a difficult type of gauges but not on 42004 series 41, good material.

Perfect fit for the new high and low pressure guages purchased with them.

Too thick between the gages
