I know we should never use one of these but every time I find my self in that fix that needs me to use a 3/8" socket but cant get enough turn on it so go for the 1/2" breaker bar and ever time I end up twisting the 3/8" male part off.

So can any one suggest a 1/2" to 3/8" Reducer Adapter that will stand up to the job ? and one I can get in the UK would be handy ;)

What socket are you using that you cannot break free on a 3/8 drive, but the 1/2 drive equivalent isn't available to use?

Not quite a case of "isn't available" just the case that it was not available at my place at 22:00 on a Sunday I broke 2 as I needed a 19mm 12point to take a crank shaft pulley off. As all my 1/2" sockets are 6point

I have a Sunex impact and a Snap-on non-impact, was thinking about selling the SO because the Sunex looks really good but after reading the drama today about impact adapters breaking I am rethinking, and honestly hoping to never need an adapter.

Mac or Snappy with replaceable end. I have a 3/8 - 1/4 with a replaceable end, although I think I only used it a 1 or 2 times in the past few years.

I've broken a few of those myself. I'm going to try an impact version next.

You also might want to look into a long 3/8 breaker bar.

$10 craftsman 3/8" breaker bar + cheater pipe

Problem solved. I'm actually amazed at how much abuse they can take. Haven't broke mine once yet.

Do you have a 12pt 3/4" in 1/2" drive?

I can't remember the last time I had to use my 1/2" to 3/8" adapter !

First, I try switching from my standard 3/8" ratchet (admittedly pretty short) to a flex head 3/8" which is almost twice as long.

Second, if I need my 1/2" breaker bar I use 1/2" sockets. Period.

Hey, Snap-On used to have the AIMF for this purpose. Supposedly up to 2000 lbs according to the stamping on it. They normally go for $20 on eBay.

I used a Craftsman reducer w/ a 19mm socket and cranked my torque wrench up to 150 ft-lbs and it took it like a champ. Just wanted to see if they would do it. I'm surprised it didn't break.

them up-sizer adapters look useful... where can i find something like that?

They do work well and are very low profile. I have a set from ???. Matco had them in chrome at one time and I think Grey Pneumatic still makes theirs.

I've snapped off a couple of the SK reducers and they will not replace them, says so right on them. Same deal with the SK 3/4" to 1/2" reducers. I think I still have a broken one laying around somewhere from many years ago.

Pleading ignorance here, can someone explain why an impact extension is acceptable but one of those SO adapters are not suitable for impact use.

Am guessing that a 3/8" socket may not be able to handle the amount of torque a 1/2" gun could deliver (more an issue of the socket vs the adapter) :dunno:

It's about metallurgy, things made for impact are tougher and less brittle, but not as high tensile strength.

Thanks, I assumed by the black steel they were of similar material to that used for impact use

thank you. im gonna look into a set of them. upsizing isnt common, but i definitely dont like the upsizers that resemble the downsizer this thread is about. the low-pro seems much stronger design and obviously, much lower profile.
