Parker CPI™/A-LOK® Tube Fittings are ordered by part number as listed in this catalog.
Size: Tube and pipe thread sizes are designed by the number of sixteenths of an inch (1/2" tube = 8/16" = 8)
(1/4" pipe thread = 4/16" = 4).
Straights & Elbows: Call out largest CPI™/A-LOK® tube end size first followed by the smaller CPI™/A-LOK® tube
end or pipe thread size.
Tees & Crosses: For drop size tees – first size the run (1 to 2) and then branch (3). Example – the size designator
for a male run tee for 3/8" O.D. tube and 1/4" male pipe thread would be 6-4-6. For crosses – first size the run (1 to 2)
and then the branch (3 to 4). For tees with all ends the same, use the tube and size before and after the style designator;
i.e. 4-4-4 JBZ (CPI™), 4ET4 (A-LOK®).
Type: A letter or combination of letters and numbers are used to designate the type of fitting. (i.e. SBZ or MBT = male branch tee, GBZ or
FA = female adapter,etc.) See the visual index for fitting types.
Material: Basic material type (B = brass, SS or 316 = stainless steel, type 316; S = steel; A = aluminum; M = Alloy 400; HC = Hastelloy C-276 ®;
IN = Alloy 600; SS20 = Carpenter 20®; 6MO = 6Mo; 625 = 625; 825 = 825; T = Titanium). Parker CPI™/A-LOK® Tube fittings, for special applica-
tions, can be furnished in almost any material suitable for machining.
Special Fittings: If there is any question as to the fitting desired, particularly for special fitting configurations, it is suggested that a
customer print be submitted with the fitting request for quote.
Availability: Items priced in current price list 4230/4233 are carried in stock. Price and delivery for non-stocked items quoted on request
through the Quick Response Department.
Parker CPI™/A-LOK® tube fittings part numbers are constructed from symbols that identify the size and style of the fitting and material used.
Example: The part number shown below is for a Parker CPI™/A-LOK® stainless steel male connector for 1/2" O.D. tube (–8) and 1/4" male
pipe thread (–4).

written as a fraction (i.e., 1/4 NPT = 1/4N).
Straights & Elbows: Call out largest CPI™/A-LOK® tube end size first followed by the smaller CPI™/A-LOK® tube
end or pipe thread size.
Tees & Crosses: For drop size tees – first size the run (1 to 2) and then branch (3). Example – the size designator for a male run tee for 6mm
tube and 1/4" male pipe thread would be 6-4-6. For crosses – first size the run (1 to 2) and then the branch (3 to 4).For tees with all ends the
same, use the tube end size after the style designator; i.e. JBZ 4-4-4 JBZ (CPI™), ETM4 (A-LOK®).
