Question by: Curt R on May 12, 2025, 9:49 AM

Got a line running 1/4 inch NPTF female and need to tie into a 7/16 SAE O-ring boss port. this the right adapter for that?

Answer by: Customer Support on May 14, 2025, 6:43 AM

That's exactly the configuration this part handles. The 2216-4-4S runs a 1/4 inch NPTF female on one end and a 7/16-20 SAE O-ring boss male on the other, straight through with no angle. Carbon steel construction and the Dura-Kote plating give it solid corrosion resistance, so it holds up well in demanding environments. Weighs under a pound and ships as a single unit.
