Glowshift's 1/8 BSPT Male to 1/8-27 NPT Female Thread Adapter was made for oil pressure, fuel pressure and temperature sensors that will not thread into your stock port. If youre using this brass adapter with a temperature sensor, 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 connection that prevents any leaks. At GlowShift Gauges we also back any purchase with unrivaled Customer and Tech Support.
