Brennan 0304 C 10 Steel Flared Fitting Review

So I give 4 stars because the product is ok. However, based on the photo I thought it was a JIC tube nut that goes behind the sleeve. Instead, it's a union nut, which is what you would use if you wanted to cover a fitting (no pipe on top). They're cheap enough and I'm not worried about returning a few I've bought, but wanted to write a review in case anyone looking for a tube nut also stumbles across this item. If you are looking for a union nut, this is the one for you. very meaty.
