The set includes both large and small adapters plus Viton O‑rings to seal the junction and is machined from carbon steel for strength and corrosion resistance. It’s designed to thread into the pressure tube at the rear of the steering booster pump and accept the factory flared line without additional modification.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the adapter let an LS pump work with older 3\/8\" flare lines?\u003c\/h3\u003e\n\u003cp\u003eThe adapter threads into the pump’s M16-1.5 port and presents a 5\/8-18 fitting that a 3\/8\" flare line can connect to, converting the thread and sealing method.
