GlowShift’s 1/8-27 NPT Female to 7/16-20 Male Thread Adapter allows you to install a 1/8-27 NPT oil pressure, fuel pressure, air pressure or nitrous pressure sensor to any 7/16-20 port. This brass sensor adapter essentially acts as a bridge between the sensor and vehicle port, 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. You will be able to get equally effective readings for your air pressure gauge adapter or nitrous adapter as well. This adapter includes an O-ring for a leak-free seal, but it is also recommended that you use Teflon tape on each thread to create an even more secure and reinforced connection to prevent any leaks. GlowShift includes free lifetime tech support and a one-year limited warranty with each thread adapter purchase.
