AtecoUniversal Pastry Coupler and Cap Set | 7 Piece Set | Works with 250 Ateco decorating Tubes plus tips from other brands

I'm embarrassed to say I have likely never thrown away a frosting tip. I have some that are really old. Over the years I have loaned them out and lost a piece here and there. Was looking at buying a new kit and came across this. Every one of my frosting tips worked on one of the couplers. For less than $7, I am back in business. Good quality. This was a really good find for me.

The media could not be loaded. I see that most of the negative reviews are confused by this product and frustrated by the lack of instructions. The instructions were literally on the outside of the box I received (see pictures) and all of the parts are labelled on the part itself. There are two coupler bases (large and small) For full interchangeability and use, you put the largest coupler base on the piping bag. L, ML, and M tips will all attach directly to this; you just change the size of the tightening nut (again they are labeled) to correspond to the tip size. The cap is a really nice feature; it only fits on the large coupler base.The small coupler base (which holds S tips) also attaches directly to the large coupler base. You secure it to the large coupler base with the M tightening nut. If you are only using S tips and do not care about full interchangeability (and are not using the cap), the small coupler base can be used independently of the large base.How well this works with non-Ateco tips I cannot say, but it looks like there should be *some* flexibility. YMMV.Yes, I did not tighten them on all the way in my video. That is why they are so wobbly. Tighten them properly and it won't be an issue.

The media could not be loaded. I did not like there aren't instructions. I do love the convenience.

I found when I went to make churros, that the bag I used was apparently too thick, because the coupler kept coming off. Will try with thinner bags in the future.

Added this set of couplers to my amateur cake decorating supply kit to accommodate larger piping tips. They work fine and it’s nice to have additional small tips available when swapping in and out many colors. If I had endless funds I’d just get the regular not universal couplers for all sizes as the size adjusters are kind of an extra step and a pain to keep track of. But they’re economical, work perfectly well, and take up little extra storage space.

Other pastry bags that I bought, thinking they were large, said they were large but they were not. I make cream puffs and other pastries and I don't want to keep filling it. This bag is quite sufficiently big and so are the attachments. Easy to clean and I'm sure you'll like it.

I wanted to try Eclairs for the first time and resorted to ziplock bags because my star tips weren't big enough so i made a makeshift plain tip to work with. The Eclairs turned out HUGE and were still good but not uniform. So i ordered the bag and coupler and it went perfectly with a 869A star tip which resulted in smaller eclair shells that all looked pretty similar with less cracking.

Like some other reviews mentioned, the “L” larger size coupler is gigantic, measuring 1-5/6" (33 mm) meaning that your tip bottom has to be larger than this, otherwise it will go right through the hole in the coupler.Then there is a “ML” (medium-large) coupler that measures 1-1/8" (28mm). This one will fit 1-1/4 -inch tips.I had bought this coupler for the “M” medium size coupler thinking that it would be slightly larger than the smaller standard size.However there is a very huge difference in size between the Small and Medium size couplers.Many decorating tips measure about 7/8 -inch (22 to 23 mm) diameter at the bottom.The Medium coupler is too large, and these tips go right through the hole in the Medium size coupler.This Medium coupler is really for large tips.The hole on this Medium coupler measures 7/8 inch (22.5 mm). You need to use it with a tip that has a 1 inch diameter at the bottom or larger.Like already mentioned in these reviews, NOBODY makes a coupler for the tips with a bottom diameter of about 7/8 inch.Since there are no couplers on the market for these 7/8 inch tips, you cannot change the tips without emptying your bag. This is not efficient.The description of the item says : “This Universal Coupler accommodates ANY decorating tip with an bottom opening between 0.5 inch to 1.5 Inch, it will fit nearly all tips available from any manufacturer”THIS IS FALSE advertising.The smaller coupler fits standard tips measuring 11/16 inch diameter. This is more than the 0.5 inch mentioned in the add.This coupler is useless to me.
