A/C 1/4" Thread Charging Hose Gasket,Sealing O Ring Kit Replacement Rubber Gasket Seals for A/C Refrigeration Charging Hose(100 Pack)

I only needed one of these seals, which means I now have a lifetime supply.It easily replaced the leaky seal on my HF branded gauge set, enabling a leak-free filling experience. My car's AC was recharged quickly and easily.Given my minimal use, I cannot speculate on the longevity of these seals. However, since I do not rely on them for my livelihood, nor do I use the gauges frequently, any failure might stem from infrequent use rather than normal or excessive wear.Based on my experience, I believe the product deserves a 5-star rating.

I've been through several types of gasket looking for the perfect fit on my testo smart probes. These are it. I wouldn't suggest using them on your ball valve hoses because these are a little smaller and they'll turn into projectiles when you open the valve, then you'll lose the core depressors. Ball valve hoses work best with yellow jacket gaskets but my testo probes work way better with these, and the price is awesome. The rubber is pretty soft so don't tighten them too much or it'll rip.

These fit the standard HVAC guages used for cars, split systems and residential systems. They give you enough to last the rest of your natural life. Good quality and seal. I have more faith in them than the original black rubber and the hsrd white seals.

Materials feels nice but they fit too loosely to feel safe about using them at work every day. Could probably get away with using them on my field piece probes versus yellow jacket hoses since there’s not a lot of pressure backed up but did not want to risk losing my core depressors. Too late to return but ordered the yellow jacket gaskets right before typing this up.

These don't exactly fit a Yellowjacket manifold gauge hose but I think they'll work. I installed one, placed the depressor in the seal and hooked it up to a tank of refrigerant with no leaks. Checked it with soap bubbles. Seems OK and for the money much better that Yellowjacket's price.

THEY ARE GOOD QUALITY BUT DONT FIT MY GAUGES

Buena calidad
