Steel Metric Flareless Fitting, 30.00 mm S Series Union

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.

You bet, this here's a steel fitting.

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.
