Question by: Ray B on Dec 28, 2025, 3:10 PM
trying to replace a hex plug on an ORB port, is this the one with the 7/16-20 male thread?
Answer by: Customer Support on Dec 30, 2025, 10:38 AM
The key callout is the male SAE O-Ring Boss thread at 7/16-20. This part is a steel hex plug in the Danfoss 900598 series, and it includes seal part 22617-4.
Question by: Judy F on Mar 20, 2026, 2:42 PM
Will this plug work for hydraulic applications in a chemical processing plant?
Answer by: Customer Support on Mar 22, 2026, 6:58 AM
It's definitely suitable. This steel adapter is listed as being applicable for chemical processing environments.
Question by: Marvin W on Mar 4, 2026, 7:13 PM
seal included with this plug, or do i need to order that separate?
Answer by: Customer Support on Mar 6, 2026, 5:55 PM
Seal part 22617-4 comes included with this adapter, so you won't need to track one down separately. That's the O-ring matched to the 7/16-20 thread, and it's already accounted for in the package.
Question by: Merle P on Oct 9, 2025, 11:36 AM
what industries is this plug actually rated for? trying to figure out if it'll hold up in our processing facility
Answer by: Customer Support on Oct 10, 2025, 6:22 PM
The 900598-4S carries application coverage across some pretty demanding environments, including chemical processing, food and beverage processing, pulp and paper, marine and military, and offshore drilling. A processing facility context lines up well with what this fitting is built around.
