Product Description
Radiator hose sensor adapter is cast aluminum and fits into the upper radiator hose. Threaded with either 1/8" BSPT, 1/8" NPT or 3/8" NPT port to accommodate most aftermarket coolant temperature sensors.
Allows you to install a coolant temperature sending unit for an aftermarket gauge or a thermostatatic switch without having to drill and tap your existing metal pipes. Our design allows install into the curved portion of the upper radiator hose for a perfect fit. Simply cut and trim the upper radiator hose and install this adapter in-line. Includes the two additional clamps you'll need.
See options below to select the appropriate thread pitch. Autometer gauges and many thermostatatic switches have a sending unit with a 1/8" NPT (27) thread pitch. Most of the gauges and electronics made Japan including Defi, Greddy, Apex-i, HKS have sending units with a 1/8" BSPT (28) thread pitch. Spal Thermostatic Fan Switches sold here at Z1 are 3/8" NPT (18).
Measures an approximate 35mm (1.38'') in diameter.

Does this come with an insert or plug so that you can plug it off if you are getting a sensor at a later date?
It does not standard but if you need one just call in and one of our reps can sell you a plug with it to ship together.
Hi, I bought the z1 radiator hose kit and I want to buy one of these to fit a water temp sensor.
Firstly, which size one will I need considering I have the z1 silicone hoses?
Secondly, will I lose any coolant during the install, and if so should I just flush the system?
Richard,
This will work great with the Z1 Silicone hose. You will need to cut a section of the existing hose to make room for this adapter and you will more than likely loose a little coolant because you will have to cut that hose all the way through twice. Regards, Austin I.

It is as advertised. You need one with two 1/8" npt holes

I have a temperature sender on the rear heater hose which is probably fine but this going directly in line from the engine to the radiator is going to give you accurate engine coolant temp.
