Glowshift's 1/8-27 NPT Female to 1/8 BSPT Male Adapter is ideal for oil pressure, fuel pressure and temperature sensors that will not thread into your stock port. If the threads of your sensor and your vehicle stock port do not match, this brass sensor adapter acts as a bridge between the two, enabling a seamless and effective installation. As a fuel pressure gauge adapter, this accessory will enable you to take extremely accurate fuel pressure readings. As an oil pressure sender adapter, you will be able to install your oil pressure sensor for accurate oil pressure readings. If you are using this adapter as a temperature sensor adapter, a test port sender extender must be purchased since most temperature sensors will not fit through the borehole. It is also recommended that you use Teflon tape on each thread to create a secure, reinforced connection that prevents any leaks. GlowShift includes free lifetime tech support and a one-year limited warranty with each thread adapter purchase.
