Rated 1 out of 5 by 1 reviewer.
Rated 1 out of 5 by NIBCO union is well below Home Depot's standards I was incredibly disappointed that Home Depot would sell a product as poor quality as this NIBCO 1/2" Copper Union. I've been through 6 of these so far (I need 4) and each requires 'finishing'. Specific issues include: Large gap on the male surface prevents simply polishing Very rough female surface making leak free mating impossible 2 unions had threads that would not mesh - too rough, requiring manual cleaning 1 union had a male part that was too large to go through the collar, significant effort to ream the collar to open up Dear Home Depot buyers: Please express our dismay to NIBCO on their dismal product. (I'm apparently not the only customer unhappy with this poor quality product, which cost 1/3 more than a competitive product at Lowes). Take NIBCO off the shelf and find another vendor that offers the quality NIBCO used to be known for. Thank you. February 27, 2014
