The ID designator is calculated as follows:
X · 32 = Y
Use the formula:
X - inch/decimal number of ID required.
Y- ID designator.
When a 1/2 inch (.5 inch) ID is required the designator is figured as follows:
.5 · 32 = 16
Designator would be 16.
1.2.4 End configuration (see figure 1).
A - One male/one female fitting
B - Female fittings, both ends.
Blank - Bulk hoses.
1.2.5 Fitting material.
B - Brass
S - Steel cadmium plated.
T - Steel zinc plated
Blank - Bulk hoses.
1.2.6 Length bulk hose or assembly length in inches. Lengths of hose are represented by inches and
fractions are expressed in 1/8 inch increments (1 thru 7).
Note: For the inch designator insert the number zero in front of designator for lengths less than 100
inches.
Examples:
When 12 and 7/8 inch length is required the designator is: 012-7.
When 120 and 3/8 inch length is required the designator is: 120-3.
When 96 inches is required the designator is: 096.
