IMPORTANT NOTE REGARDING THREAD DASH SIZE/TUBE DASH SIZE
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:
JSEAL
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.
