exposed threding is that okay?

[monkey_mo]

So after finding out that the barbs I picked up were threded to long, I thought at first fml... but then thought why not just see how far these barbs can go. After a good 5minutes tightening each barb, they are impossible to move unless with the aid of a wrench (with a lot of force into the turns). My question is, is this okay to do? I tested it by connecting it to my faucet and there were no leaks but im just a little worry that there is about 1/4" of threding extruding from the port. Should I apply epoxy around the exposed threding? If this all a bad idea then someone should tell me

Pics of the exposed threding:

If its a bad idea can someone help me out as stated bellow, would be awesome:

Im already so over budget on this rig and having to spend more for shipping than the barbs themselves is just escalating my price even more, so what im asking is if anyone can simply add these 2 barbs and ill come by your place (obviously paying you the cost as well) to pick them up. Seems silly that for 2 little barbs the cheapest option is $13 from Canada post, but anyway if there is someone in Vancouver (Burnaby, Richmond, it doesn't really matter where in GVR) it would be awesome. Im at that point that I just cant afford to spend even an extra $1 more than I need to.

You may want to clarify which barbs you're looking to buy, other then that I can't help you friend.

oh is the hyperlink not working? well I forcefully managed to get them in this far into the rad (pics in the OP) opinions is this okay to do? If what im doing is not recommended then these were the adapters I was looking at https://www.dazmode.com/store/produc...o_g1_4_female/

Where did you get those barbs?
Are you sure they are G¼ threads? Not say a 3/8" NPT which is a tapered pipe thread?

Are you sure the rad is also G¼ thread. What brand of rad is it?

The link your posting to shows a G3/8 male to G1/4 female, I don't see how that would help you out.

its the older pa 120.2 its which used G 3/8 threding. I just got today my koolance g3/8 to g1/4 females, which as you can see are a little exposed. I thought the port was going to have enough threding inside the rad. Theres about 1/4" of the threded part of the barb sticking out, that's my concern, but in my simple testing there was no leakage at all.

You may be okay. I would keep leak testing for a couple of days - maybe even move the rad around to see if any leaking happens. Hopefully it doesn't!

[monkey_mo]

yeah its been under the faucet for the last hour and a bit, no leaks. I honestly thought I was going to break the rad when I tightening the barb, if water can squeak through id be extremely shocked but for extra safety I was going to put some epoxy around the base of the port.

Parallel threads will not seal themselves and require another type of seal (like an o-ring). They really only provide a force for the o-ring to seal.

Having extra threads proud doesn't matter as long as you get enough force on the o-rings to seal. But if not enough force is given, then you could end up with a leak.

Tapered threads seal against each other (no o-ring) but will often use thread tape or dope to assist.

From the pics, it looks like you are using a tapered thread. Make sure both the res and barb are designed for the same thread profile. If not, you could end up cross-threading and wrecking both!

I'm afraid you might damage your rad by the looks of the fittings, it looks like they are NPT fittings which are 18 threads per inch with a 1 3/4 % taper. G1/4 and G 3/8 are straight threads with 19 threads per inch, you should never have to force things when it comes to cooling equipment ! Proper G3/8 to G 1/4 would have been easier, however you may get lucky and have no problems down the road.

well that's great to hear... But after close inspection there appears to be no damage to the barb threding. I didn't force twist the barbs to much after it stoped twisting nicely on. So these are the barbs I needed wasn't it? http://www.dazmode.com/store/product...o_g1_4_female/ I wanted them originally but then thought they be to short. No objections to these ones to be used with my rad gdesmo? and thanks for the help guys, I didn't even know about the different thred/inch, always assumed they were all the same.

Yes please use those correct adapters, when in doubt give any of us a shout. And throw those barbs away or give them to someone you don't like !

Try not to ever use teflon tape in a computer cooling system, a loose piece can plug part of a water block or ruin the seal on a pump if it gets wedged in between the rotor shaft and the seal. Pipe dope will kill your biocide if you are using it so don't use it either plus it does not play nice with some plastics.

daz really needs to make $5 shipping on orders under like 5lbs or something around there!!!!!!!

Sorry but the postal service is not as cheap as you think it might be. I ship a few things and am not surprised at the charges at all, it is a combination of weight and physical size that determines the price.

ive shipped motherboards to quebec (and im from Vancouver) for just under $20 insured as well, ive just wondered that as little stuff like O-rings a couple of barbs can easily be slipped in a padded envelope which is always less than $5 cross county, whenever ive used my CP Business account. Its an honest question because last order, my shipping cost would have been the exact same if I were to add in one of those molex dc psu's in a package containg just barbs. Im not saying daz is ripping us off but there is something odd about that.
