The 9/16-18 SAE 2-way high-pressure steel block valve with Viton seals (part GE206SAEV) swaps the standard Buna-N O-rings for Viton (FKM) — the seal to specify when the line carries fuels, hot oil, or media that attacks nitrile. Quarter-turn solid steel block body, zinc chromate plated, Delrin seats, SAE straight-thread O-ring boss ports that seal on the O-ring rather than the threads.

Hydraulic power units, cylinder isolation, test stands and gauge circuits. SAE straight-thread O-ring boss ports seal on the O-ring rather than the thread — the standard choice on hydraulic manifolds and equipment ports.
Cross-References & Interchange
Replacing another brand's 9/16-18 UNF high-pressure ball valve with FKM trim? Match thread size, working pressure, and port style — or send us your part number and we will confirm the interchange. Standard hydraulic oils at normal temperatures? The 9/16-18 Buna-N version (GE206SAE) covers general service.
