content: I've got a venerable Hakko 937 soldering station. Works great. I wanted to put a narrower (1.6mm) chisel tip on it. Thus, seeing they're supposed to be compatible, I ordered the T18-D16 tip. However, after removing the outer sleeve, putting on the new tip, and replacing the sleeve, the new tip basically falls out of the sleeve. The hole in the tip of the sleeve is too large to secure the new tip.I believe the wand is the factory 907 tip, but the markings are worn sufficiently that I can't tell that. (Maybe there's another way to tell?)Is anyone else having this experience? What's the solution? 900M tips only?GeekPriest

content: Well, I don' know your country so I can't tell you where to buy, but the 937, using the 907 wand, uses the 900M tips. This is here in the US:http://www.techni-tool.com/657TI751?gclid=CjwKEAjw9dWuBRDFs9mHv-C9_FkSJADo58iMueb0vh52Y2FlHnr3RQvMv_7BM8iId0KnANECTt-HYRoCgS3w_wcB&ef_id=VMa90QAABK@RQx@w:20150821020350:sYou can hunt down OEM, don't buy the 10 for a buck ebay tips. They suck.

content: If there are holes on the tip sleeve this is a strong indication you have a 900L (large capacity) sleeve and tip.I've seen some clone stations that come like this from China stock.The Hakko website shows the dimensions of the tip series, the standard 900M and T18 series (both compatible with each other) are 2mm smaller than the large capacity tips.http://www.hakko.com/english/maintenance/topic_936_937_928_kote.htmlIf this is the case you will need is a new sleeve and collar to use standard size tips. If you are using a clone they are fairly cheap and common on ebay, I cannot guarantee it will be a perfect fit though so choose wisely.If you want a genuine one look up a Hakko dealer and hopefully they have what you need.

content: Thanks for this information. I will examine the wand when I am in the basement next time.

content: It does appear I have the 908 iron, which takes the 900L tips. I'm going to try fitting an aftermarket 907 sleeve and nut onto the iron so it would take the 900M tips. Failing that, I'll search out some 900L tips.

This guy has the same problem and mentions what kit you need to look for on ebay. He seems a bit confused himself about genuine parts (only genuine is from Hakko or a Hakko reseller). All depends if you have a 907 or 908 threaded handle, anyway hopefully for $10 or so you get it sorted.

content: Good to know I'm not the only person with this confusion.That video is rather long-winded, though. His critical mistake is in not understanding that the base stations (936, 937, FX-888, etc.) can take multiple irons (small, medium, large). My station has the 908 (large) iron, but the labeling has worn off. :/ That slowed me down some.Waiting for the 907 (medium) collar and nut to show up so I can get my 908 to take the much more common, and less expensive, medium (900M/T18) tips.

I also got an extra 5 900L-T-3.2D tips from tequipment.net. I would have bought the conversion kit from them but they don't have it anymore.I still use the 907 but not often, but that 907 is the cloned one, maybe one day I get an original hakko one.Edit: this is an old picture when I got it, now it's not so shinny and new
