Oil Fittings & Lines Selection Guide

Technical Information & Buying Guide

Turbo oil fittings connect the engine’s pressurised oil supply and gravity drain to the turbocharger. Correct thread type, fitting size, restrictor selection and hose routing are essential for reliable lubrication and leak-free installation.

The oil feed must provide the pressure and flow required by the turbo bearing system. The oil drain should generally run continuously downward to a suitable engine return above the oil level, without sharp bends or restrictions. Do not identify fittings by appearance alone; confirm thread standards and dimensions before ordering.

  • Confirm turbo and engine thread types before selecting fittings
  • Use the appropriate feed restrictor where specified
  • Keep the oil drain large, unrestricted and correctly routed

FAQ

  • Are turbo oil fittings universal?
    No. Turbochargers and engines can use different metric, imperial, tapered or straight threads.

  • Does a ball-bearing turbo require an oil restrictor?
    Many do, but the required restriction depends on the turbo and engine oil pressure. Use the manufacturer’s specification.

  • Why is the oil-drain fitting larger than the feed fitting?
    The feed is pressurised, while the drain normally relies on gravity and therefore requires a larger, unrestricted return path.
