Super Lube 98003 Silicone Heat-transfer Grease 3 Oz

Product Description

The SUPER LUBE 98003 is a silicone-based heat-transfer grease packaged in a 3 oz tube. It is formulated to improve thermal conductivity between components such as heat sinks and the surfaces they contact, reducing hotspots and improving heat dissipation in electronic and mechanical assemblies. The compound has a maximum operating temperature of 450 degrees F (260 degrees C) and presents as a white paste. HVAC technicians, electricians, and electronics service professionals use this grease when installing or servicing heat sinks and thermally loaded components that require reliable heat transfer across contact interfaces.

This heat-transfer grease is suited for residential and light commercial applications wherever thermal interface management is required. Common install scenarios include applying the compound to heat sink bases before mounting on control boards, variable-frequency drives, power transistors, and similar components found in HVAC equipment, electrical panels, and industrial controls. The 3 oz tube size supports field service work and bench repairs where a controlled, mess-free application is needed.

Key Features

• Silicone-based composition provides stable performance across a wide temperature range up to 450 degrees F
• White paste formulation allows visual confirmation of coverage during application
• 3 oz tube format delivers precise, controlled dispensing for heat sink and contact surface work
• Suitable for use on heat sinks in both field service and shop environments
• Compact tube dimensions (6.5 x 2.13 x 1.3 inches) fit easily in a tool bag or parts kit

Compatibility

Designed for use on heat sinks and thermally loaded contact surfaces in electronic and electromechanical assemblies. Consult component manufacturer specifications to confirm suitability before applying to specific substrates or materials.

Installation Notes

Applied by licensed HVAC technicians, electricians, and qualified service professionals during component installation or replacement. Power down and de-energize all equipment fully before accessing control boards or heat sink assemblies. Apply a thin, even layer to clean, dry mating surfaces to ensure proper thermal contact. Avoid over-application, which can cause compound migration onto adjacent circuitry.
