fitting says M 26x1.5 thread -- does that match up with an 18mm tube line or is that the port size on the equipment side?

Question by: Johnny B on Jul 7, 2025, 8:49 PM

The M 26x1.5 is the thread size on the fitting itself, and the 18mm refers to the outer diameter of the tube it's meant to plug. So you'd be looking at an 18mm OD tube line paired with that M 26x1.5 threaded connection. Both specs work together on the same fitting, not on opposite ends.

got an 18mm tube line i need to cap off. is this the plug that matches that size, or am i lookin at it wrong

Question by: Diane G on Oct 24, 2025, 9:43 PM

For an 18.00 mm outside diameter tube in the L Series, this part is the matching tube plug. It’s specified as an 18 mm L Series tube plug with an M 26x1.5 thread.
