There are over 20 inherent properties of fuser film sleeves relevant to specific gravity, temperature index, melting point, tensile strength, dielectric strength, film thickness, coating thickness, and others directly affect performance. Failure to strictly adhere to the OEM manufacturing and material standards will cause the sleeve to crinkle, crease, tear, melt, or otherwise prematurely fail. A recent study has shown that the thickness of both base and coating materials for aftermarket sleeves can vary up to 20% versus OEM.

Over the past 15 years, the fuser film sleeve market has become flooded with low cost, inferior quality products produced by Chinese manufacturers, but our commitment to availability, customer satisfaction, and quality has never wavered. National Parts Depot was one of the first companies to offer replacement fuser film sleeves in the mid 1990's. All of our sleeves are manufactured in Europe using a 100% internally controlled production of both our polyimide base material and metal cores. In addition, sleeves are inspected and rigorously tested to ensure their performance on all types of media and operating conditions. Our aim is to provide the widest selection of OEM quality products at a reasonable cost.
