Works Great By ww_big_al on 4/14/13ww_big_al would recommend this product to a friendNeed a quick shut off valve for my RO tank and these appear to be high quality. I gave it 4 stars instead of 5 because the description is confusing. They are identified a 1/4" inch or 3/8" fittings. They are refer to the ploy tube size. Both have 1/4" FNPT for the RO tank. The descriptions need to ID that fact. I ordered the 1/4" fist but of course they didn't fit me 3/8" tubing.
Perfect replacement! By Oscar on 8/7/12Oscar would recommend this product to a friendMy old connection to the RO tank had no valve. This is perfect. Very solidly built and works perfectly without any leaks!
