GM uses an adapter which threads into the case cooler ports and is sealed with a washer. The adapter converts the thread to inverted flare for hard line usage. The cooler ports on the T-350 are usually a female 1/4"-18 NPSM (National Pipe Straight Mechanical (NPSM)) and use a metal washer/seal. The NPSM threads will fit a NPT (tapered) fitting, but if a tapered fitting is to be used, be careful to not over tighten it. | GM uses an adapter which threads into the case cooler ports and is sealed with a washer.
