Compy Lube Kit
The “Compy” Seal By-Pass Lubricating System eliminates bearing damage from water intrusion. This
system compensates static lube oil pressure in a trailer axle by using a “divers bell”.  It is the only
trailer lube system that compensates for the effects of “ Hot wheel and cold water”—hence eliminating
the vacuum that draws harmful water into your trailer axle’s bearing.  When this happens the bearings
fall apart, the wheel comes off and becomes a rolling projectile--- A SAFETY HAZARD to all on the
road!  Pressurizing the hub with more grease simply blows out the seals causing water to enter the
bearings resulting in bearing failure.  Venting and pressurizing the hub solves the problem.  The
automotive industry uses venting on all their differentials.  Our system duplicates venting on the trailer
hub via a seal by-pass line. This keeps the hub slightly positive and compensated with the added
water pressure when launching and retrieving. Added together, these two pressures create positive oil
pressure in the spindle at ALL times.  Water penetration is NOT possible!  Sound simple?  Well it
really is.
SBL - 100   "Compy Lube Oil Kit"

Contains the major components needed to
retro-fit existing trailer axle spindle / hubs to
the maintenance free pressure
compensated lube oil system. Unlike
existing grease or oil systems offered by
others, our system keeps the water out by
compensating for submerged water
pressure and the negative pressure caused
by cold water submersion.

Wheel bearing & mechanic's, servicing tools
& experience required to install.

Some miscellaneous materials must be
provided by installer.
