The fin and tube coolers are cheaper to manufacture but are larger per amount of cooling capacity than the stacked plate design. If there's adequate space for mounting, the fin and tube can do a good job. | The fin and tube coolers are cheaper to manufacture but are larger per amount of cooling capacity than the stacked plate design.

The threaded case port on the TH350 is either a female 1/4-18 NPSM (National Pipe Straight Mechanical) thread, and it uses a metal washer/seal. The straight thread fitting is the most common. | The threaded case port on the TH350 is either a female 1/4-18 NPSM (National Pipe Straight Mechanical) thread, and it uses a metal washer/seal.
