It is highly recommended to only use Sealube lubricant when replacing pump shaft seals (10ml. tube). This is a water-based formula designed to lubricate rubber and make the installation of mechanical seals easy. Don't use those silicone based lubes on the market, because if some of that gets on the seal face, it can be very difficult to remove - shortening the life of the seal. Why make your job harder? Use this tried and proven U.S. Sealube seal lubricant. It also extends seal longevity. Store in a cool dry place.

 This product is also used by aircraft and sailboat owners as well as by homeowners for other applications, but it is especially useful to use when installing new pool and spa pump seals. This product lubricates and protects.
