Where the Hell can I find these freaking fittings!? (1/8" BSPT)
 
1 Attachment(s)
Been searching around for awhile to find replacement hose barb fittings for my APEXi Boost Solenoid as one was sheared off in an accident. Thought I had found out that they were 1/8" NPT. Everything thread in smoothly until about 4 revolutions, then it got QUITE difficult to turn. After doing some searching I found out that the required fitting is actually a 1/8" BSPT. EFF! Been searching for hours with no luck. Found one place in the UK that wouldn't ship to the US... Checked McMaster as well with no luck. Basically I am looking for a (2) hose barb fittings with 1/8" BSPT male and 3/16" hose barb. Attachment 198661

If it threads in 4 rotations why not JB weld and thread until it jams up.

I'm NOT sure:giggle:
I did get fittings that look exactly like that there though

Reverend Greg 04-07-2010 03:30 PM

I hate that there are two pipe threads,If you can take it a part and tap it to NPT...you will make it easier to get fittings for...

your propably going to have to get a different size barb. I looked as well and it seems that the size your talking about just isn't made. I found some with 5/32 barbed and 1/4 barbed, but nothing in between. Its kinda wierd.

This is UBER close... I will check and see if I can get away with fitting a 1/4" ID hose on a similar fitting. :crosses fingers:

Mitchell, no JB Weld for this reason...Trying to avoid damaging the solenoid or modifying it as I plan to get rid of it once it is fixed... So yes, an APEXi AVC-R will be up in the FS section sometime soonish.

18psi, they were 1/8" NPT at Ace. That's where I got the ones that only thread in 4 rotations. :facepalm:

Brain, you are correct sir...

LOL no fucking way. You might be able to get it at a local mom & pop hardware store, but you'll have to give pops some hand relief to convince him to special order it, perhaps from jolly old England or wherever they use British pipe thread.

Here's a mcmaster part that may help:
5832T111
3/4" long pipe nipple with 1/8 BPST on one end and NPT on the other. To that you could attach a common 1/8 female NPT barb adapter. Assuming the additional length isn't a problem for your application.

Dude if you get really desperate I'll try the local hydraulic fittings place and see if they can get one, then ship it over to you. PM me the EXACT fitting you need and I'll give them a call.

edit: just re read the original post and I see you have already posted what you are after. Its past 9 in the evening now but ill try calling them in the morning if you like just to see if they have it and how much. Let me know if I should bother.

Appreciate it man... If all else fails here in the States I will let you know something for sure.

dustinb 04-07-2010 04:24 PM

Are you 100% sure it's BSPT? Being Japanese it's more likely a metric fitting.

thagr81 us 04-07-2010 04:26 PM

Tried metric fittings with the thread finder thing. None worked... Plus it is tapered.

localtech 04-07-2010 04:44 PM

sell it like it is. You may be better off just letting the next person deal with it. With fittings being 2-5 bucks here in the States I am sure the fittings from UK will be a lot more shipped.

It's cool that you are going to this extent to sell a good part though.

thagr81 us 04-07-2010 04:53 PM

Yeah... I thought about selling it like it is. Also, I am fabricating a new mounting bracket for it as well as the other got destroyed in my accident. Just trying to make sure the buyer doesn't have to go through all of these hoops to have a running unit.

if you're using silicone vac hose, it'll work fine. just pretend it's prom nite again. she'll stretch over you.

94blackmx5 04-07-2010 05:29 PM

jegs sells a 1/8 bspt to 1/8 npt adapter.

BarbyCar 04-07-2010 11:46 PM

I bought a couple of cheapo oil pressure gauges and they came with a bunch of brass adaptors including 1/8BSP to 1/8NPT. (The Miata oil pressure switch is 1/8BSP). Anybody close to you have a box of old fittings they didn't use when they put a gauge on their Honda?

I did exactly that on a Kia water neck, in order to plug some BPT holes with NPT plugs.

rweatherford 04-08-2010 12:09 AM

Sorry I don't have time to look but try to look here.

http://www.teejet.com/

If you can't figure it out call them and tell them what you are trying to do. They handle both NPT and BSPT items. Hope they can help you. If not they may know someone who can.

[EDIT: I looked at TeeJet and the closest I can find is a 1/4 hose barb nozzle adapter which requires two other parts to get everything you need, but the barb size is wrong. They do not have a 3/16 size that I see.]


Here is a 1/4 x 1/8 BSPT which you might be able to adapt your hose easier than finding the fitting.

Also I think Hagie sprayers are all BSPT, which makes them a PITA, but they also might be able to help you.

thagr81 us 04-08-2010 01:06 PM

Think I'm going to get the 1/4" ones from the link above and hope for the best... Now can anyone find a 1/8" BSPT to AN-03 adaptor? Haha!

Actually if you get desperate this works. I have done it with Permatex gasket maker on water temperature sending unit fittings (1/8" NPT threaded into BSPT on the block) and it works fine. No leaks, long term.

For a boost solenoid I would not think twice about it since there are no fluids involved. Even if it leaks a tiny, minuscule amount (which it probably will not) it will not hurt anything.

Dumb question, but you do know that NPT (tapered) threads are SUPPOSED to do this, right? That is how they seal; there is an interference fit with the threads.

thagr81 us 04-08-2010 02:02 PM

Honestly I would do the JB Weld method if I wasn't trying to turn around and sell the unit after it is repaired. I have one of the original fittings provided by APEXi and the taper on it is WAY more pronounced than the NPT fittings I purchased before knowing any better. I can get a full ~10 rotations by hand on the original fitting before needing a wrench to tighten it 2 more revolutions. Just trying to get the unit back to factory specs prior to selling it... Regardless of the effort I have to go through to do so. Thanks for all of the help guys, it is GREATLY appreciated.

astroboy 04-08-2010 03:09 PM

Do you still have the old fitting? If so get a fitting with the size barb you need, cut the new barb off, and braze it to the old fitting. Much easier if you can braze/know someone who does.

thagr81 us 04-08-2010 03:11 PM

I only have one of the old fittings, but I need two to complete the unit. Otherwise that would have been my plan... In my accident the hose barb portion got sheared off and only left only the threaded portion. Pic below...

Attachment 198620

ZX-Tex 04-08-2010 03:43 PM

If you can get the old fitting out, cut off a barb and braze it to the inside of that fitting maybe. Or cut off the very end of the threaded portion and braze it like Astro said. That or just a piece of tube that is slightly larger than the I.D. of the hose. It will seal well enough (for temporary use) with a bunch of zip ties.

Personally I would just order the right fitting from mcmaster or the like.

This is what I did earlier today. Ordered the one that was really close to what I'm looking for with the 1/4" hose ID barb. Should be okay in theory... I will update upon testing.

rweatherford 04-08-2010 08:04 PM

Found this place tonight....

Try this for BSPT to Flare. Not sure what the angle is for AN.

Quick look, it's steel, but 1/8" bspt to AN-03 gay: http://www.pegasusautoracing.com/pro...p?Product=3230 .

Pegasus has lots of bspt stuff, just no barbs from the quick look I gave it.

b14 se-rious 04-09-2010 12:06 AM

Why dont you just tap it for 1/8 npt

thagr81 us 04-09-2010 10:00 AM

^ :facepalm:

Thanks for looking out for the AN-3 adapter for me guys. Steel or not, that one from Pegasus might be worth it. Now I just wonder if it is BSPT... Makes a difference as the BSP doesn't have a significant taper on it like the BSPT.

[EDIT]: Upon investigation of the Pegasus Racing offered fitting, it is the parrallel thread fitting and not the tapered like I need. FML.

rweatherford, thanks again man. I might just go up to AN-4 on the size. It will be used for my BOV and Wastegate fittings, so it should be more than enough overall air volume to make both function quite well. And the angle on AN is 37°.

thagr81 us 04-10-2010 10:17 AM

Fittings arrived this morning via UPS from McMaster's ATL Warehouse... Test fitting is a go! The barb is just a LITTLE bit larger and longer, but should not be an issue for the buyer. Thanks again for all of the help guys!

And to answer someone else's question from earlier, in this case, yes, the Japanese DO use British Standard Pipe threads for their fittings (at least GReddy and APEXi do). O.o
