Glowshift's 1/8-27 NPT T-Fitting Adapter allows you to add up to (3) 1/8-27 NPT devices to (1) 1/8-27 NPT socket. This adapter is optimal for temperature sensors, pressure sensors and oil feed lines. If you are installing two or more temperature sensors, we recommend using a sensor thread extender before threading the temperature sensor to the T-Fitting. At GlowShift Gauges we also back any purchase with unrivaled Customer and Tech Support.
