Hi and welcome to the forum...I don't know of such a thing. Some of the other folks in the group might know. I used to use whats called a "Ferrofluidic" seal. Look at www.ferrotec.com "The operation is realized by the character of magneticfiud responding to magnetic field. As shown in the drawing, the magneticfluid sealing apparatus is consisted of magnetically permeable shaft, pole piece, magnetic fluid and magnetic loop. The magnetic field force on top of magnetic pole is the strongest point on which magneticfluid sealing concentrates. The seal purpose will be realized by filling in the sealed gap which is formed by the shape of a "Liquid O-ring".   Modified by Marky at Thu, Nov 19, 2009, 14:43:52
