AN-6 -> M16x1.5 Bump Tube - Power Steering / Opel Astra EHPS

This AN-6 to M16x1.5 adapter is typically used for power steering, where the system is converted from an OEM power steering connection to an AN hose. It is relevant for solutions where a more flexible and motorsport-oriented layout of the power steering system is wanted, for example when using braided hoses and custom power steering installations.

The adapter is made with an M16x1.5 bump tube connection and suits applications where this OEM type is used on a power steering pump or power steering line. This type is, among other things, commonly referenced for Opel Astra electric / electro-hydraulic power steering pumps, where conversion to AN-6 on the hose side is often carried out. This makes the adapter suitable for motorsport, engine swaps, and other custom builds where a strong and service-friendly solution for power steering is wanted.

It is important to distinguish between thread type and sealing type. M16x1.5 describes the actual thread, but in this type of application it is especially the bump tube connection that is critical. It should therefore not be confused with other M16x1.5 fittings that use a different sealing type.
