Building custom fuel, oil, coolant or brake plumbing on your 1988-1998 Chevy/GMC C/K (OBS/GMT400) truck? This ColorFittings AN adapter works on 2WD C-series and 4WD K-series 1500, 2500 and 3500 pickups, plus GMT400 Suburban, Tahoe and Yukon builds.
This ColorFittings -10 AN to M22x1.5mm ORB Adapter is precision CNC-machined from 6061-T6 billet aluminum and finished with ColorFittings' proprietary anodized coating for corrosion resistance and long-term durability. The M22x1.5mm O-ring boss thread seals on the O-ring rather than the flare, giving a reliable leak-free seal on ORB-style ports. Built to handle high-pressure, high-temperature fuel, oil, coolant, and power steering plumbing. Available in 7 colors.
Universal AN fitting compatible with 1988-1998 Chevrolet/GMC C/K, Suburban, Tahoe, Yukon, Blazer, and Jimmy trucks and SUVs when adapting O-ring boss ports to AN.
