Coolant temperature sender thread pitch?

[Racer X]

As the title states... does anyone know the thread pitch of the temp sender? I'm looking to install some gauges, and this is the only sensor that I can't find the thread pitch for.

Its NPT for sure I can't remember if its 1/4 or 1/8" if its 1/8" NPT it is 28 tpi

Just for the record, could you post up the thread specs for the other senders you're looking at adding?

I got a spare, and I'll keep it in my pocket... goin to Lowes sometime tonight or tommorow, and I'll let ya know dude if no one knows first. You are talking about the one with the one pin deal right? Not the one with the connector? Just the push pin thing?

Yup, that's the one, thanks!

On the other sensors, the oil temp sensor is going to replace the oil pan drain plug; it's M14 x 1.5 IIRC, and the oil pressure sensor is 1/4 NPT, again, IIRC.

I'mma get a pic just for sport.. then see whats up..

 

[Racer X]

That's it.

 

[Eric VerValin]

Gotcha, I'll let ya know in about an hour dude..

Pretty sure thats 1/4 npt.

 

[Eric VerValin]

I'm thinkin more like 5/8 cause they didn't have anything there, but there were a few guys in agreement it was definately NPT.. 5/8 maybe 3/4 but I think it's 5/8 by lookin at it.

 

[Ishodu]

Thats 1/4 NPT.

 

[Eric VerValin]

thats seems kinda small ? my finger is more than 1/4 inch wide.. lol

 

[Sho_Freak]

pretty sure its 1/4 npt. 5/8 or 3/4 npt is HUGE

the starting major DIA of 1/4npt is 0.48(iirc), and drill size is 7/16 or .4375(also iirc). it goes by the od of the pipe. so 1/4" pipe with 1/8" wall thickness is 1/2" or .500. the threads are tapered to seal with a little torque on em.

 

[SHOtime2511]

yeah,1/4 NPT

 

[Eric VerValin]

ok then.. if thats the case.. it's realllll close to a half inch.. so yep... 1/4.. lol


And don't you mean the ID? of that pipe?

 

[Ishodu]

Yeah its from the nominal ID of the pipe up to 10"

 

[Sho_Freak]

ok then.. if thats the case.. it's realllll close to a half inch.. so yep... 1/4.. lol


And don't you mean the ID? of that pipe?

Lol yup. Just noticed that... Nice eye!

 

[Racer X]

Did some more digging, and it seems that a few reference the size as 3/8-18 NPT.

Sound right to you guys?

 

[Ishodu]

Just take the thing to the hardware store and try and screw it into a few fittings.

Take it to the local Fastenal or plumbing supply house and check for sure. Just sayin'
