TUBING ADAPTER AND REDUCERS
Tubing adapter consist of a machine tube stub (metric or fractional OD) on one end and a male or female thread second end.
These fittings have two distinct advantages:
They greatly reduce inventories tube fittings. By stocking union tees and union elbows, plus a few various adapters, a wide variety of male or female elbows, male run, male branch, female run or female branch tees can be made up with a minimal inventory investment.
- Male Elbow
- Union Elbow
- Female Port
- Male Adapter
They eliminate difficult alignment problems by simplifying the proper orientation of elbows, tees, and crosses without regard to pipe thread tightness.
- In Fig. 01, the require installation is to connect tubing to a female port (in the direction shown).
- With pipe connection tight, the male elbow is pointing in the wrong direction for the desire tubing run.
- To correct this situation, merely tighten the pipe thread of a male adapter into the female port.
- Connect a union elbow to the adapter by tightening the connection with a wrench while holding the elbow in the desire direction. Then insert the tubing into the other end of the union elbow and connect the tubing.

Reducers are somewhat similar to tube adapters in that they have a machined tube stub on one end and a connection on the other end. Reducers are use to convert from one fitting tube end to a different size tube end. For example, the 1/2 in. tee (SS-TTT-FL8) shown (see Fig. 02) is required to have 1/4 in. OD tubing from its run port. A reducer (SS-R-FL8-FT4) complishs the conversion in a single step.
Fitting reducers, port connectors, and adapters have a machine groove near the end of the tube stub. This groove is precisely position to receive the ferrules during fitting pull-up. The groove is critical to proper ferrule action because it simulates the action of the ferrules as they would perform on annealed tubing.
Because of the substantial differences in tolerances, dimensions, and sealing methods, considerable variations in sealing position exist between tube adapter-type fittings and those of other manufacturers.
USE OF ADAPTERS
Align elbows, and tighten the nut according to installation
Install the tubing run to the elbows, thus completing the installation.
The bulkhead reducer fitting is found particularly advantageous for ease of alignment when connecting tees or elbows behind a bulkhead. Examples of this type of application are shown in Fig. 05.
- Union Elbow
- Male Elbow
- Union Tee
- Female Elbow
- Union Tee
- Male Run Tee
- Female Run Tee
Applications of bulkhead reducers with standard tube fittings installation.
USE OF ADAPTERS FOR VALVE INSTALLATIONS
When installing a valve, there is usually a prefer location for the valve handle. For example, if the valve is coming off a piece of equipment, it is often desire to have the valve handle locate directly above the valve as shown in Fig. 06.
If the connection on the equipment is a male or female pipe thread, alignment is extremely difficult, if not impossible. The result is usually something like Fig. 07.
To save time, stop leaks, and prevent valve damage during installation, use a male or female adapter (see Figs. 08 and 09).
To orient your valve, screw the male adapter fitting into the equipment (see Fig. 10).
Using a valve with integral tube fittings, slip the tubing stub from the adapter into one connection. Hold the valve vertical while pulling up the nut according to installation instructions, and the valve is properly oriented (see Fig. 11).
If it is desired to shift the direction of the valve handle, loosen the nuts on the connections, move and hold the valve at the desired location, and retighten the nuts.
