Question by: Wes W on Aug 24, 2025, 1:52 PM
what exactly is a "union" type fitting, does that mean both ends connect to tube, or is one end something different?
Answer by: Customer Support on Aug 26, 2025, 1:34 PM
Both ends connect to tube. A union is a straight, tube-to-tube connector that joins two separate tube runs of the same size together. On this particular fitting that's 30mm tubing on each side, so it's used when you need to connect two lengths of metric tube in line without any thread or port on either end.
Question by: Wes W on Aug 8, 2025, 7:45 PM
Is this fitting made of steel, or is it some kind of substitute?
Answer by: Customer Support on Aug 10, 2025, 3:33 PM
You bet, this here's a steel fitting.
Question by: Kent C on Aug 21, 2025, 9:54 PM
got a 30mm line on a machine, is this the kind of union that just joins tube to tube?
Answer by: Customer Support on Aug 23, 2025, 9:50 AM
Meant for joining two metric tubes together, this is a 30.00 mm S Series flareless union in steel from the Danfoss and Eaton Waltech tube fitting line under the Eaton Aeroquip brand.
