Having trouble finding this part - Tee Hose Connector

[CountZero23]

I've fitted a turbo gauge my RX7 which recently stopped working, along with turbos due to the hose connector t piece snapping.

Blocking up on end of a t-hose connector and just hooking up the turbo line without the gauge line has me up and running but now I need to find this bit.




It has two hose connectors and screws into a brass fitting on the turbo kit.

I'll need something like this.

For reference, the bolt on it is 10 mil.

How do I find out the correct fitting with the right screw pitch and gauge?

Ideally, I'd like a metal piece so this doesn't happen again as it gets very hot under the hood which is probably what made this so brittle.

Can anyone suggest the part I need?


If not, would buying a 'Screw Pitch Gauge Combination' and 'Stainless Steel Drill Gauges metric & Imperial gauge' do the job?

Any advice on where to buy some proper metal bits to replace it with would be great!

Try cbsonline.co.uk

They have a huge variety of this and other stuff

Think Automotive will have something that'll fit. A little bit of a trek for you but if you bring the old part then they'll be able to match the threads and suggest the best combination of fittings.

Can you put some sizes up, diameter of thread and hose barbs?

I'll guess at 1/8 bsp thread and 6mm (1/4") hose?


Something like this... tee piece.
And a couple of these... hose barb

Thanks for the tips guys, I'll try to get some measurements done over the weekend!

Thank you for the link V8 it looks a useful site

I've used the screw pitch gauge and drill gauges to take some measurements.

Screw side:
In inches: 25/64 (fits most of the way, small) 13/32 (fits but maybe a bit big)
mm: 10mm - 10.5mm (10m can't quite fit through / 10.5mm fits through snuggly)

Hose tails:
Inches: 15/64 (won't fit with the barbs but probably around what tube is), 1/4 fits through easily but a larger diameter than the tube.
mm: 6.0 mm (too small to fit in with barbs but about right for the tube) 6.5 mm (probably a bit large but fits through)

Thread: both 26 g and 1.0mm seem to work.

Any more advice on what I probably need to buy gladly received, so far I've ordered these bits.



Cheers

Steve

I think you're trying to identify the thread type and size.

You need to know whether the original is parallel or tapered. Straight edges held on opposing sides will tell you that. You need to know the thread pitch. A thread pitch gauge will tell you that. You need to know the outer diameter of the thread, or the min and max outer diameter if it is tapered.

Yup, I've got a thread pitch gauge. It's either tapered is slightly stripped at one end.

Going to have a go with what I've ordered and see how I get on

This is the sort of thing I'm referring to:

It shouldn't matter whether the thread is worn or tapered - you should be able to tell the thread pitch pretty conclusively because only exactly the right pitch thread gauge will sit down into the thread over its whole length.

Cheers fella, this is the one I've bought.

It's coming out as either 26 g or 1.0mm, 1.0mm seems the best fit.

Found it a bit wider at one end when using the drill gauge, think it's more a case of wear than taper.

If in doubt, screw a piece of dowel into the opening it is supposed to screw into - that might make it easier to see whether the hole is tapered.
