ACUiTY's 1/8 NPT to -8 O-Ring Boss (ORB) adapter is made from 7075-T6 aluminum for strength, and its silver anodized finish ensures high cosmetic quality and resistance to oxidation. It's a great option for those wanting to discretely mount a fuel pressure gauge to the side of a fuel rail or fuel pressure regulator. These were designed for use with ACUiTY's K-Series Fuel Rails, but they are perfect for use in any gas, ethanol, or gas/ethanol mix fuel system where a -8 ORB port must be adapted to a 1/8 NPT Port (which is a common size used for sensors and fuel pressure gauges). The fitting comes supplied with a -908 FKM o-ring that is gasoline and ethanol (and E85, etc) compatible. Additionally, each fitting is designed with a flange at the base of the 7/8" hex to help protect against scratching the part the fitting is being threaded into during tightening. 

If replacement o-rings are needed, order ACUiTY part number 1913-F08 (which includes 5pcs of -908, FKM O-Rings).

See below for examples of the fitting used to adapt fuel pressure regulators onto ACUiTY's K-Series Fuel Rail (1913-F05 fitting comes with fitting and o-ring only, gauge and fuel rail sold separately)
