Steel Adapter, 1-7/16-12 Male SAE O-Ring Face Seal To 1-1/16-12 Male SAE O-Ring Boss (Straight Thread O-Ring), Straight

Match it up by the ends and threads. One side is a male SAE O-Ring Face Seal (ORS) with 1-7/16-12 threads, and the other side is a male SAE O-Ring Boss (ORB straight thread O-ring) with 1-1/16-12 threads. It is a straight steel adapter in the FF1852T series.

Marine applications are indeed one area where this adapter can be put to use, along with things like chemical processing and offshore drilling.

You read it right. One end is a 1-7/16-12 male SAE O-Ring Face Seal, which is your ORS connection for that 1-inch OD tube line. The other end is a 1-1/16-12 male SAE O-Ring Boss, which threads directly into a female ORB port on your valve or manifold. Both connections rely on O-ring sealing, so no thread sealant is needed on either end.

It sure will. This adapter is specifically made to connect those two sizes of SAE O-ring boss fittings.

Function-wise, it is a straight steel adapter that connects a 1-7/16-12 Male SAE O-Ring Face Seal end to a 1-1/16-12 Male SAE O-Ring Boss straight-thread end.

Marine, offshore drilling, chemical processing, pulp and paper, and food and beverage use are all listed applications for this fitting. Steel construction handles the mechanical demands of those environments well, and the O-ring face seal on one end combined with the O-ring boss on the other gives you two solid leak-resistant connection points. That dual-seal setup is part of why this series gets used in industries where fluid containment really matters.
