Titan part 151-155 is an airline lubricator used in pneumatic spray systems to inject a controlled mist of oil into the compressed air line. This lubricates air motors, valves, and cylinders, reducing wear and extending component life. Replace a clogged, leaking, or non‑adjustable lubricator to ensure proper air motor lubrication, prevent premature failure, and maintain consistent operation on PowrTex 15:1 and Commander units.

The Titan 151-155 Airline Lubricator is a pneumatic accessory designed to inject a precise, adjustable amount of oil into the compressed air supply line. It is typically installed in the air line between the air regulator and the air motor or pneumatic controls. The lubricator ensures that internal components such as air motor vanes, seals, and valves receive continuous lubrication, reducing friction, heat, and wear.
Over time, lubricators can become clogged with dried oil residue, develop leaks in the bowl or seals, or lose adjustability. A faulty lubricator results in inadequate air motor lubrication, leading to sluggish operation, increased wear, overheating, or complete air motor failure. Replacing a worn or clogged lubricator with a genuine Titan 151-155 restores proper oil delivery, extends air motor life, and ensures reliable pneumatic system performance on PowrTex 15:1 and Commander models.
| Lubricates air motor | Provides oil mist to internal vanes and bearings |
|---|---|
| Reduces wear | Minimizes friction and heat in pneumatic components |
| Adjustable oil delivery | Allows tuning of drip rate for different air flows |
| Cracked or leaking bowl | Visible cracks or oil weeping from the bowl or seals |
|---|---|
| Clogged internal passages | No oil delivery even when full and adjusted |
| Seized adjustment | Drip rate adjustment screw will not turn |
| Air motor running dry | Sprayer runs rough or slows due to lack of lubrication |

When replacing the airline lubricator, inspect the air line components.
Replace or clean the air filter and check regulator function at the same time.
Inspect for cracks, leaks, or restrictions that could affect lubrication.
If the lubricator failed, the air motor may require inspection or rebuild.
