The MIDLAND INDUSTRIES SS6410-10-10 is a straight extender adapter designed for SAE O-Ring Boss (ORB) hydraulic and fluid system connections. It features a 5/8-inch Male O-Ring Boss inlet and a 5/8-inch Female O-Ring Boss outlet, making it a same-size pass-through extender rather than a reducer or expander. Constructed from 316 stainless steel, the adapter delivers strong corrosion resistance for demanding environments. The body measures 1.5 inches in length with a thread specification of 7/8-14 on both ends. It is rated for operating temperatures up to 1000 degrees F, supporting high-heat fluid system applications. Licensed plumbers, hydraulic system technicians, and industrial pipefitters are the typical installers.
This adapter fits within the SS6410 Series, which covers MORB to FORB configurations in stainless steel. It is suited for residential and commercial fluid systems where SAE O-Ring Boss fittings are standard, including hydraulic lines, fuel systems, lube oil circuits, and high-temperature process piping. The stainless steel construction makes it appropriate for installations where corrosion from moisture, chemicals, or high heat is a concern. Its compact 1.5-inch body allows installation in tight plumbing runs where thread extension or connection bridging is needed.
Designed as an OEM-style fitting for SAE O-Ring Boss fluid systems requiring a 5/8-inch male-to-female straight extender in 316 stainless steel. Part of the MIDLAND INDUSTRIES SS6410 Series of SS SAE O-Ring Adapters.

Torque fittings according to the system manufacturer's specifications and applicable industry standards.
