Question by: Jimmy W on Feb 7, 2026, 3:54 PM
What's this fitting made of, and how cold can it run before it starts giving trouble?
Answer by: Customer Support on Feb 9, 2026, 6:03 AM
Buna-N is the material here, which gives you solid sealing performance across a decent temperature range. The rated minimum working temperature comes in at -25°F, so it holds up fine in cold environments without the seal breaking down on you.

It matches 2 inch end size on both ports, and the second connection is listed as a Line/Hose/Tube end type.

Reckon this fitting will work alright with some hydraulic oil I got on hand?

Buna-N rubber is generally resistant to petroleum-based fluids, but it's always best to check the fluid compatibility document to be absolutely certain it's suitable for your specific application.
