TUBE Dash Size – THREAD Dash Size
|
The RYCO Dash Size Part Numbering system for Connection Types associated with Inch
sized tubing, follows the THREAD size rather than the TUBE size.
For example, for JIC 37° Flare; 9/16” THREAD is used with 3/8” OD TUBE.
The RYCO DASH SIZE for a JIC Hose Tail, 3/8” Hose to 3/8” Tube Size is therefore
-0609 (not -0606).
The Connection Types this applies to are as follows:
|
JIC 37°
UNO (O Ring Boss)
ORFS (O Ring Face Seal)
SAE 45°
SAE Inverted Flare
|
BSP, NPT, JIS, Metric DIN, and SAE Flanges are not affected.
The tables below show the relationship between TUBE Dash Size and
THREAD Dash Size. |
