LS Engline Oil Pressure Gauge Adapter Fitting

The LS Engine Oil Pressure Gauge Adapter Fitting is a precision banjo-style adapter designed for mechanics and performance enthusiasts upgrading oil pressure monitoring on LS-platform engines. This adapter bridges the gap between modern aftermarket gauges and factory oil system ports, enabling accurate real-time pressure readings during street driving, track sessions, or engine diagnostics. Whether you're tuning a fuel-injected LS swap, troubleshooting oil delivery issues, or installing a digital dashboard, this fitting provides the critical interface your gauge needs.

Manufactured from black anodized aluminum, the LS Engine Oil Pressure Gauge Adapter Fitting features a 16 mm x 1.5 banjo inlet that connects directly to LS engine oil ports, with an NPT 1/8 inch outlet that accommodates standard aftermarket pressure gauges and sensors. The banjo design allows for flexible hose routing around engine bay obstructions, while the included crush washer ensures a leak-free seal without risk of over-torquing fragile gauge fittings. Anodized aluminum construction resists corrosion in high-heat engine bay environments while remaining lightweight—critical for minimizing parasitic weight in performance builds.

This adapter is essential for LS engine swaps, turbocharged LS builds, and any custom engine bay where factory gauges have been removed or relocated. It works seamlessly with mechanical and electronic oil pressure gauges rated for NPT 1/8 inch connections, making it a universal solution across LS1, LS2, LS3, and LS9 variants. Installation requires basic wrenching skills and fits in tight engine bay layouts common to street rods, track cars, and restomod projects where precision monitoring prevents catastrophic engine failure.
