Question by: Joyce W on Jun 16, 2025, 12:33 PM

does the 0.614 inner diameter on this one match up with a 5/8 tube OD system, or is that a seperate measurement altogether?

Answer by: Customer Support on Jun 17, 2025, 8:46 PM

Both numbers refer to the same fitting setup but describe different things. The 0.614 inch inner diameter is the O-ring's own bore size, while the 5/8 inch figure is the tube outer diameter this O-ring is built to seal against. In a JIC or face seal arrangement, those two dimensions work together, so if your tube OD is 5/8 inch and you're running an FS4000 series port, this is the right ring for that connection.
