8F-CC Injector Cap with oring ( old 6F ), new part number is 1032975.Was used in older Autotrol 155, 160, 163, 168, and Technetic 1000 Valves ( cross reference PN 1032985 ).
Very old versions were white and pointed.* Obsolete part. NONE LEFT IN STOCK - Must buy 8F-BB now
This is the same cap and the "tip" of the "BB" cap can be snipped off for use as "C" cap.
Same threads - Same hole plugged by this Cap.
Styles included A, B, and C, but no different in the Cap size.
The letters were to help identify the Injector used behind the cap ( Injectors, A, B, or C ) without having to remove the Cap.
Autotrol stopped this method, and went to a single standard ( unmarked ) CAP in later years.
