Pneumatic Nomenclature
Part numbers for pneumatic fittings are constructed using symbols that denote the style and size. The first series of numbers and letters indicates the style and type, while the second series describes the size. For example, '231-8-6' refers to a Run Tee fitting with a 1/2" Tube O.D. and a 3/8" Pipe Thread.

Sizes
Tube sizes are measured by the number of sixteenths of an inch in the tube's outer diameter (O.D.).

Advantages
The fittings are compact, one-piece, push-on barbed fittings made from CA 360 or CA 345 brass rod, providing a quick and economical way to connect polyethylene tubing.

Applications
These fittings are recommended for use with Parker polyethylene tubing due to its high resistance to environmental stress cracking, ensuring long life when used with expansion fittings.

Working Pressure and Temperature Ranges
For tube sizes 1/4" to 3/8", working pressures up to 150 psi are feasible at temperatures from -65°F to +90°F. For 1/2" tube size, pressures up to 100 psi are practical at temperatures from -65°F to +75°F.

Assembly Instructions
To assemble, simply push the tube over the two barbs, ensuring the tubing is cut square.

Fittings & Tubing Specifications
The document provides detailed specifications for various fittings, including Bulkhead Unions, Union Reducers, Plugs, Male and Female Connectors, Adapter Tees, Union Tees, Union Elbows, Gauge Tees, Male and Female Elbows, Run Tees, Branch Tees, and Solder Connectors. Each fitting type is listed with part numbers, tube O.D. and I.D., pipe thread sizes, and flow diameters.

Key Data from Tables
The tables provide dimensions and flow diameters for each fitting type, allowing for precise selection based on application requirements.
