TransTec® Radial Shaft Seals
Not All Shaft Seals are the Same — Know How to Identify the Problems
Leaks can occur when your seal has a poor lip design, and can be compounded by poor manufacturing processes and lower cost materials. Lack of pumping action from a poorly designed helix, and an overly tight I.D. can also be detrimental to a good seal. Many technicians believe a tighter fit is a better sealing product. The truth is, an overly tight fit often means the seal will fail prematurely due to increased friction. Be aware of the warning signs:
An increase of friction, generates heat and reduces the pumping action of the seal.
The combination of friction, heat and reduced pumping actions, causes “coking” to occur; the liquid oil turns into a solid residue.
Coking affects the pumping action of the seal, and in turn, results in extra wear and a shorter life span of the seal.

Product Testing Results
A side by side comparison shows that the competitor’s seal wore 5X’s more than the Freudenberg-NOK seal when put through standard seal testing required by major manufacturers such as GM, Ford, and FCA.
Lip Wear Into Helix Bars = 0.27 mm
Lip Wear Into Helix Bars = 1.51 mm
With Radial Shaft Seals, You Get What You Pay For
TransTec® Radial Shaft Seal from Freudenberg-NOK
- Designed, engineered and manufactured to create the best seal performance and longevity
- Knife trim lip which has less chance of leaking, especially at initial use
- Even and consistent helix contact with the shaft for maximum fluid pumping

- Uses a molded lip – which has a higher tendency to initially leak
- Smaller inner diameter of the seal causes a tighter fit on the shaft, causing accelerated wear
- Helix contact with the shaft is not consistent
