Mechanical Temp Guage Query - Can This Part Touch Hot Oil!

[jaik]

Gday,

Ive got 2 HKS mechanical temp guages and Ive installed one already in my top radiator hose. As you can see in the picture there are 2 parts to the sensor, firstly the brass nut and then the big aluminium adaptor. Well if you unscrew the brass nut then you can remove the actual sensor from the ali adaptor. Here is a pic of them apart.

Now the thread on this brass nut is identical to that of the thread in my Greddy Spin on Adaptor, which has provision for such a small sensor. So Id like to put it in there. You can see in this close up pic of the actual sensor that it would be suitable.

My question is - is this material ok to be in direct contact with hot oil, whereas the radiator temp sensor is protected by the adaptor. I presume tho that these adaptors are only made to be more suitable for water, whereas it would obviously be too much of a restriction for oil to have such a big adaptor.

Any advice would be great.!

Oh and are these guages filled with mercury or something similar?

Cheers

JK

i think it should be ok as the sensors that came with my gauges (Apexi EL electrical) look similar to the ones u have. The sensor is ment to be used for either oil or temp as the gauges only came out as a 'temp' gauge.
