Product Questions & Answers (6)

Question by: Daryl H on Nov 18, 2025, 11:37 AM
does this adapter work for marine and offshore applications, or is it more of a shop/industrial type fitting?
Answer by: Customer Support on Nov 20, 2025, 6:59 AM
Marine and offshore drilling are both listed application environments for this adapter, along with chemical processing, food and beverage, and pulp and paper industries. The steel construction and SAE O-Ring Boss configuration on both ends gives it a reliable sealed connection that holds up in demanding environments where fluid integrity matters.
Question by: Cody G on Aug 15, 2025, 5:23 PM
got a hose end that’s 1-1/16-12 SAE ORB, will this step it down to a 3/4-16 female ORB without any funny business?
Answer by: Customer Support on Aug 16, 2025, 8:35 PM
For a straight SAE O-Ring Boss reduction, it goes from a 1-1/16-12 male SAE ORB on one end to a 3/4-16 female SAE ORB on the other, and it stays straight through.
Question by: Merle E on Jun 25, 2025, 6:29 AM
What's this adapter actually for, like what kinda stuff is it used on?
Answer by: Customer Support on Jun 26, 2025, 6:42 AM
Primarily, this adapter finds use in applications like marine and military equipment, along with chemical, pulp and paper, and food processing industries. It's also found in off-shore drilling setups.
Question by: Wes M on Jun 24, 2025, 3:34 PM
got a hose end with 1-1/16-12 male ORB, and i need to step it down to a 3/4-16 female ORB. is this the right adapter?
Answer by: Customer Support on Jun 26, 2025, 6:01 AM
Built for that exact reduction, this FF1010 series straight steel adapter has a 1-1/16-12 Male SAE O-Ring Boss on one end and a 3/4-16 Female SAE O-Ring Boss on the other.
Question by: Harvey H on Apr 28, 2025, 11:14 AM
Got a port on my hydraulic manifold that's 1-1/16-12 ORB and I need to step it down to a 3/4-16 ORB fitting, this adapter do that?
Answer by: Customer Support on Apr 30, 2025, 6:47 AM
That's what this one's built for. The male end threads into your 1-1/16-12 SAE O-Ring Boss port, and the female end accepts a 3/4-16 SAE O-Ring Boss fitting. Both connections use straight thread with O-ring sealing, so you get a clean, leak-resistant transition between the two sizes without any pipe thread complications.
Question by: Ricky W on Jun 9, 2025, 9:43 PM
I need an adapter to go from a 1-1/16-12 male SAE O-ring boss to a 3/4-16 female SAE O-ring boss. Will this one do the trick?
Answer by: Customer Support on Jun 11, 2025, 7:10 AM
This adapter will indeed connect a 1-1/16-12 male SAE O-ring boss to a 3/4-16 female SAE O-ring boss. It's a straight adapter, so it won't change the direction of the connection.
