1/4 NPSM to 8AN Male Banjo Kit for GM TH350/TH400

This kit was engineered specifically to provide a low-profile solution when connecting transmission cooler lines to the GM TH350 and TH400 automatic transmission. The stainless steel banjo bolts have 1/4-18 NPS Male straight threads, and the aluminum banjo adapters have a male 8AN (3/4-16 UNF, 37° convex flare) to accept any standard 8AN hose end. Includes two banjo bolts, adapters, and sealing washers (enough for both cooler hoses).

Designed to fit GM TH350 and TH400 transmissions with the original 1/4-18 (straight thread, washer seal) ports only. May not fit aftermarket versions or transmissions modified to use NPT (tapered) threads.

Note: NPS thread nomenclature is confusing because the "1/4" does not refer to the thread OD. The male 1/4 NPS threads measure 17/32" (0..54") OD and the female threads measure 0.49" ID.
