I just received these today and the indicators on the O2 absorbers are both pink but sealed are they still usable

If each O2 absorber is hard it is no good. If each is like sand and pliable it is still good. Although they may be several in a bulk pack, you will have to open the package and check them individually. But keep in mind, if they have hardened, they still are of a small limited use and combined with other absorbers may do an ample job. LDC

The ones I got were sealed. I do not believe you can take them apart without breaking them.

They are sealed. They are also 12V which is not what I need. I have 10 of these that I would be happy to send to you at cost.

Mine were sealed and in great condition. You should return them as damaged.

It depends on the color of the original fluid used. This is a pink color and I believe the earlier color was a deeper red.

Mine are not clear, they're definitely diffused with a hot-glue like consistency. Package says G005937. I didn't get the SKU H512 like someone stated below, so I guess we're not all getting identical parts. Not a deal breaker for $3, though.

the packets themselves don't change color but if they are opened and let open to air, they will deplete quickly, as in a couple days. There should be an indicator packet that would have been red or pink when you received it and has probably turned blue by now if it's still open. That is the only thing that will change and is intended to indicate if the package has been compromised. I only opened mine when I was ready to use packets out of it. I quickly resealed them in a canning jar with a vacuum-sealed lid. I got them more than a year ago and the indicator is still pink indicating good packets. I only open and take out when I need to use packets in something new I am sealing. And it is never open for more than a few minutes. These are best for dry items to be sealed for long-term storage.

Each vehicle is different in the amount of O2 sensors they have. Could be 1-4 or even more.If you know you only have two, the upstream is before the converter and the downstream is after it.You need to know which is bad before you replace it. Most parts stores can scan you vehicle and tell which one is suspect.

They come with factory heat seal around 3 sides, open at top. You fill them, drop in an oxygen displacement packet, and heat seal with an iron or clam shell device.

I have some leftover from a purchase from 2007. They are working fine! Keep them sealed and don't store them in a place that gets hot.

Wish I could help you with that question but mine are new and I have not had a problem with them. I would begin by contacting the company itself. Good luck with it.

It is best to store the remaining o2 absorbers in an air tight environment. I use a food saver system to re-seal my o2 absorbers.Place the proper size o2 absorber in the mylar bag prior to sealing it. Just toss it in and seal it up.

The ones that I received seem to be fine; I've used several and they all have sealed.

They have treaded holes in the pipes for O2 sensors. If you do not have O2 sensors there are plugs you can put in to seal up the holes.

I am getting the same thing. A distinct pink line on the spongey part (you have to lift up plastic, right after max line) and a pink line at the control spot. Not sure what that means, but I am also confused.

I've only had them for a month or so they've been through a car wash a few times. I sprayed the pressure washer right up at them didn't see any water inside them so they are sealed very well. And as far as heat I'm in Tucson, AZ so it's been hot not our hottest yet so I can't answer that yet. They are bright as hell (borderline blinding).

I don't remember if they were thru the sealed connector or just sealed but they are definitely sealed. this thing is great, pumps crazy fast. would buy again.
