Will Double Lip Grease Seal or Unitized Oil Seal do Better Job of Retaining Grease in Hubs

Question:

Hello, Your Redline Code 10-63, and TruRyde Code GS-2250DL are the same sizes as to ID and OD, but are they the same thickness. I would like to replace the grease seal with the oil seal to better safe guard grease from by passing the seals on my Dexter E-Z Lube axles. The oil seal looks like a better safeguard. Yes, No, or maybe? Many thanks,

The TruRyde Grease Seal # GS-2250DL referenced in your question is a double lip seal that will do a great job at retaining the grease inside your hubs. They will also exclude water and road grime better than a standard single lip seal.

The Redline Unitized Oil Seal # 10-63 you also referenced will do a nice job at providing leak protection with the dual action seal as well. The inner part on the seal will stay fixed on the spindle while the outer casing rotates with the hub. I like this design and there will be no issue with using an oil seal with your grease hubs.

I went out to the warehouse to measure the thickness on both of the seals. The Oil Seal is definitely thicker at 0.489 inches when compared to the 0.387 inch thickness on the Grease Seal.

While both seals are designed for improved leak protection, the thicker Unitized Oil Seal should do a bit better job at retaining the grease inside your hubs.
