REFEL is a specially formed, reaction bonded silicon carbide which gives superior performance in mechanical seals.

In independent tests REFEL mechanical seals have demonstrated the lowest levels of counterface wear. This is due to the fine grain structure of REFEL and the high degree of bonding between the silicon carbide grains. The mechanical seals made with REFEL have longer life, reduced leakage, and less seal failure.
