uninsulated I assume

Yep

looking at to m10x1 sensor but what connector goes on this?

Commonly found on tractors. You thinking of converting to a JX?

A normal 6.3 mm female spade terminal (uninsulated) slides on horizontally

Thanks
just need to make a new plate for the oil filler location then.

I can confirm resistance of vdo sensor is different to el cheapo.

Sensor turned up and it has a tapered M10x1 thread, anybody seen this before?

No mention of it on their website and they show it with a washer, I asked Brickwerks and they said thay never have a washer.

I have made a plate with a standard M10x1 thread fingers crossed.

Its a sender, not a sensor

Its a passive device, as opposed to a powered sensor that can be interrogated by the ecu diagnostics.

You might need to use some PTFE tape to help ensure that seals properly, or a dowty washer if it proves particularly problematic.

In Itchy's link to the VDO site there are a couple of downloadable documents. One of them says not to use Teflon tape, since the sender earths through the body.

The other one calls it a sensor

Surely VDO can't get that wrong


I saw the note on ptfe
I can only assume it will be OK but seems odd to use a taper on one thread ond not the mating thread.

Ford oil pressure switches were like that (X-Flow engines etc). You used to just screw them in pretty tight, with a bit of red Hermatite on the thread.

Doh ! of course it does, too much thinking about the fluid seal with tapered threads rather than the electrical connection. I'm pretty sure I have seen it used so the thread probably cuts through the tape to make the electrical circuit

You should use tapered threads for male and female, but as you already tapped the housing I assumed you didn't have a tapered tap.

In the automotive world it'll probably be OK, for equipment hydraulics at 10,000 psi it's a definite no -no, potentially lethal consequences. PTFE tape is being banned on many sites these days as it can be used wrongly to compensate for worn threads. You haven't got your oil pressure up to those levels yet have you itchy ?

I could make another plate but I can't find any reference to a taper thread form for M10x1?
I have a taper and plug tap but the taper tap is just to get the thread cut less aggressively and not the same as a taper thread form

Its sump oil so no real pressure.

I was meaning a taper thread form tap. You're right though, as you say it's sump oil there's little pressure so nothing to worry about until it leaks
