Want to add a pressure sensor to an oil line? This -8 union is designed to go inline with a male on one end and a female on the other. There's a 1/8 NPT port on the side. There isn't much depth available, so while it should work fine with a pressure sensor, it won't work with most temperature sensors thanks to the probe on the end.
All of our oil filter relocation and oil cooler kits use -8 lines.
