Brand: Racetech Gauges
Racetech gauges are a common sight on British formula cars, with good reason. They are compact, lightweight, and robust; ideally suited to a competition environment. Mechanical gauges are ideal for cars with total-loss electrical systems because they require no power to operate.
The Racetech mechanical Water Temperature gauge reads to 110° C* and is available with either a 7 or 9 foot capillary tube. The tube has a 3/8 BSP female gland nut permanently installed, and a removable 3/8 BSP male x 3/8 BSP male adapter fitting is supplied as standard.
If your vehicle has the more common American 5/8-18 female threads (or even more common NPT threads), an optional 5/8-18 Male x 3/8 BSP Male Adapter (Part No. 1098) can be used to replace the standard 3/8 BSP adapter.
7 foot or 9 foot?
The shorter 7 foot capillary tube is generally used on front-engined cars. The longer 9 foot tube provides enough extra length to reach most mid-engine applications. Note that capillary tubes on temperature gauges cannot be shortened or extended. They must be handled with care on installation and protected from vibration and kinking. If the tube is broken, the gauge is not repairable.
* 110° C equals 230° F. Note that this gauge only has metric markings.
