Great for sealing and lubricating o-rings, gaskets, motors, bearings and water filters. Teflon based Magic Lube will not cause leaking like the old petroleum based products. It can be used in wet or dry applications and can withstand any temperature up to 425 degrees. Completely waterproof, Magic Lube is compatible with most kinds of metal, rubber and plastic. Specifically formulated for pool and spa uses, it forms a durable adhesive film that is chemically resistant. Use this to lube the o-rings in your filter, pump lid, or any other stationary rubber.
