Hose Couplings Part Number Changes
This new part numbering system entailed adding an extra numeric character to 2-digit end style (thread/connector termination) codes, and converting most alpha-numeric end styles to a 3-digit code.
The exceptions to this rule are the following:
- “N” will remain in the end style coding where “N” currently represents NPT or NPSM
- “S” will replace current “SS” in the end style coding where “SS” currently represents Stainless Steel material
- “B” will remain in the end style coding where “B” currently represents Brass material.
These changes are further highlighted and explained in the examples provided herein on pages 24 and 25 with a cross-reference of Previous to New end style codes listed in the Index by Endstyle Number on pages 26 to 27 in the Couplings section.
To maintain high levels of Customer Service, traceability and accurate product identification, for many years RYCO has been branding both ferrules and inserts of hose couplings. RYCO will continue to provide this level of detail on hose couplings (including ferrules and inserts) bearing the new part numbering format. There will be no change to the identification grooves that currently exist, except for those new hose coupling series’ for which the basic markings/branding are represented on the graphics herein and in the RYCO Crimp Chart.
