Pax コンセントレートインサート

I was worried about getting the oven lid to seal properly, but these replacement O-rings fit snugly and the lid clicks right into place. Makes using my PAX 3 with concentrates so much cleaner.

Finally got this to work with my vaporizer, and I appreciate that it comes with extra o-rings and a replacement oven lid. The only thing is it took a couple tries to get the fit just right, but once it's in, it holds the concentrate perfectly.

The O-rings seem decent quality, but the oven lid replacement doesn't sit as flush as I'd hoped—takes some fiddling to get a good seal. It does the job for concentrates once you figure out the fit, just not super intuitive.
