The complete API designation includes the following:

• Nominal tubing size (from 1.9- to 4.5-in. OD) - represented with 2 digits
• Basic bore diameter (from 1.0625 to 3.75 in.) - represented with 3 digits

• Type of seating assembly (cup or mechanical) - C or M to indicate type
• Barrel length (ft) - single digit length
