Inner Axle Seal. Seal is 100.0 Percent rubber coated. Seal lip is supported by a garter spring applying constant force to the full circumference. Outer seal lip acts as a secondary seal. Keeps debris and other contaminants away from the inner seal lip.

Figure A:
Deflection gaps in the Brand X seal are the result of the spring clip opening. Fluid is allowed to bypass the seal lip through these deflection gaps. The result is a leak.
Figure B:
The Trail Safe seal lip is totally supported by a garter spring. The spring applies constant force over 360.0 Degree, not allowing any deflection gaps. This means no fluid leaks.
Figure C:
The spring clip opens up under deflection and no longer supports the seal lip. A deflection gap will allow fluid to bypass the seal, resulting in a leak.
Figure D:
The Trail Safe Inner Axle Seal uses a garter spring which offers 360.0 Degree of support around the seal lip during deflection. This stops fluid from bypassing the seal lip. No leaks.
Figure E:
Brand X's attempt to seal the Outer Diameter of the seal. Generally the material is scraped off during installation, resulting in a leak.
Figure F:
The Outer Diameter of the Trail Safe Seal is 100.0 Percent rubber coated so that it forms a complete static surface seal resulting in zero leaks.
