piston o-ring, when run continuously for very long at all. At least that's been my experience. Usually the nylon-looking piston ring survives, but the silicone looking o-ring under it deforms and then the compressor fails to build pressure. As someone mentioned here, this can happen in one afternoon of heavy, but not even close to fully continuous, on the job use. The cheap HF pancake compressor only holds up for very intermittent use. Sometimes they put them on sale for $40 so you can't expect much from them. HF sells no replacement parts; they are destined for the landfill instead!

On the other hand, I was able to resurrect my dead HF pancake compressor by stretching two very tight mil-spec Viton o-rings into the piston groove under the nylon ring. It now seems to handle longer run periods, but I don't think I'd ever trust it to feed a Shoebox.
