Stainless 316 Mbspp X Fnpt

Description & Features

Constructed from 316 stainless steel, this straight adapter connects a 3/8" male BSPP thread (G 3/8 - 19) on one end to a 1/4" female NPT thread (1/4 - 18 NPTF) on the other, making it a practical solution for joining British and North American threaded connections within the same hydraulic circuit. The straight profile keeps the assembly compact, with an overall length of 34.1mm and a 22mm wrench width across flats.

The Stainless 316 Mbspp X Fnpt is suited for hydraulic and fluid system applications where corrosion resistance is a priority, particularly in marine, chemical processing, or washdown environments where 316 stainless offers reliable performance against aggressive media and moisture. Manufactured by Adaptall, this fitting follows their standard thread-to-thread adapter design.
