Review on Lemoy 1/4" OD Quick Connect Water Tube Fittings for RO Reverse Osmosis Filters - Pack of 30 by Brian West

I've seen several complaints about bad odors and check valve failures. Took a risk and ordered because the price is so cheap how can you complain. Although I couldn't open the check valve with my breath, I hooked one up to my air compressor and they opened at 20psi. Not sure why it's not defined as a spec, but they work. You can't check that just by blowing. NOTE: Make sure you insert the tubing deep enough to avoid a potential leak. Mine also arrived and I can't report any "fishy" smell. In general it was better than expected judging by other reviews. would recommend.
