Aeroflow GM TH350 & TH400 Transmission Cooler Adapters (-8AN to 1/4″ NPSM)
Upgrade your GM transmission cooling system with high-flow AN plumbing using this precision-machined adapter pair from Aeroflow Performance.
Overview
Designed specifically for GM Turbo-Hydramatic 350 (TH350) and Turbo-Hydramatic 400 (TH400) gearboxes, the Aeroflow AF375-08BLK adapter fittings allow seamless conversion from standard 1/4″ NPSM transmission cooler ports to high-performance -8AN braided lines. Constructed from premium grade 6061-T6 billet aluminium with a sleek black anodised finish, these adapters ensure maximum flow rate, superior corrosion resistance, and leak-free fluid transfer under high pressure and temperature conditions.
Each set is supplied as a pair complete with high-purity copper sealing washers, eliminating the risk of thread distortion or case fluid leaks inherent in standard tapered NPT fittings.
