Stainless Steel Adapter, 7/8-14 Male SAE O-Ring Boss (Straight Thread O-Ring) To 9/16-18 Male JIC 37 deg Flare, Straight

Description & Features

Manufactured from stainless steel, this straight adapter connects a 7/8-14 Male SAE O-Ring Boss (straight thread O-ring) end to a 9/16-18 Male JIC 37° flare end, providing a reliable transition between these two common hydraulic thread standards. The straight configuration keeps routing direct and compact, while the O-ring boss thread design provides leak-resistant sealing at the SAE end without relying on thread deformation.

The Stainless Steel Adapter, 7/8-14 Male SAE O-Ring Boss (Straight Thread O-Ring) To 9/16-18 Male JIC 37 deg Flare, Straight is part of the SSP Fittings Corp range of stainless straight thread O-ring to 37° flare adapters. With an overall length of 1.5 inches and a tube O.D. of 0.38 inches, it is suited for hydraulic and fluid system connections where corrosion resistance and material compatibility are priorities, particularly in environments where carbon steel fittings would be unsuitable.

got a hose end that’s 9/16-18 JIC, but the port on the valve is 7/8-14 ORB. is this the right little adapter to tie those together?

Answer by: Customer Support on Oct 23, 2025, 4:48 PM

For that exact mix of ends, yes. It’s a straight stainless adapter with a 7/8-14 male SAE O-ring boss on one side and a 9/16-18 male JIC 37 degree flare on the other, meant to transition between those two thread styles.

Question by: Judy B on Apr 10, 2025, 3:14 PM

got a hydraulic line on a piece of farm equipment running from an SAE O-ring boss port and I need to tie into a JIC fitting downstream. this adapter go between those two?

Answer by: Customer Support on Apr 12, 2025, 6:34 AM

That's exactly what it's built for. One end is a 7/8-14 male SAE O-ring boss thread and the other is a 9/16-18 male JIC 37 degree flare, so it bridges those two thread standards in one straight fitting. The O-ring boss side seals with an O-ring rather than depending on thread deformation, which makes it a dependable connection at that end. Straight configuration keeps the routing clean without any offset.
