What Is Compy Lube?
 | Compy Lube SBL-100 system combines proven lubrication technology to finally solve boat | |
| trailer wheel bearing failures due to water intrusion. |
- We know what your thinking; there's at least a dozen companies out there with well made, nice
looking products, making the same claim. Some have served the boat trailer industry for a long time.

What's Different About Compy Lube?
| There's no slick packaging or fancy chrome hubs. In fact, most of the parts are standard | |
| industrial fittings. Our system was developed by commercial fishermen with over 30+ years of launching and retrieving in saltwater, usually on a daily basis. We know what the issues are! | ||
| It attacks the root cause of water intrusion. Produces a slight positive pressure without the danger of | |
| over-pressurizing, by venting through a compensating diver's bell. |
| Compy system uses lube oil flooded wheel hubs. Yes, we know others have tried this and | |
| several are on the market. The difference is ours compensates for pressure changes both positive & negative. This is the only way to keep water out of your bearings. Hubs heat up when traveling causing pressure build-up, pushing grease or oil through the wheel seal "the only avenue for pressure to escape". Those greasing-caps with spring assemblies allow for expansion but do not vent the pressure. Grease still escapes. Next: When hubs submerge during launching quick cooling occurs causing a negative pressure in the hub. The combination of water pressure on the outside and negative pressure inside the hub will force water through the seal. It only takes a few drops to destroy a bearing. | ||
| Only our system uses a remote vented reservoir with a water pressure compensating bell to | |
| keep internal / external pressures equal or slightly positive at all times! |

How Does It Work?
 | Great for the environment, reduced leakage of lubricant. | |
| Axle lubricating oil is pressure balanced with surrounding water when submerged. | |
| Compensates for temperature changes without loss of lubricant. | |
| Maintenance Free | |
| Retro-Fits existing boat or wet service utility trailer axles to oil lubrication. | |
| Free yourself from the ritual greasing ceremony every time you launch & retrieve your boat. | |
| Avoid the frustration of ruined boating vacations due to wheel bearing failures. | |
