Auburn S85-500 Coupling Kit
The Auburn S85-500 is an essential #88 NYLOFLEX COUPLING KIT designed for high-performance oil burner motor coupling applications. This 4-piece HVAC replacement part is engineered to provide a secure and flexible connection between the motor and fuel pump, effectively reducing vibration and mechanical wear within heating systems. As a direct Crown KK100 replacement, the Auburn S85-500 kit features a 6-inch Nyloshaft that can be custom-cut to fit specific installation requirements, ensuring a versatile solution for service professionals. The kit includes three color-coded end pieces for easy identification: a 1/2-inch black end piece, a 7/16-inch blue end piece, and a 5/16-inch red end piece. Industry-leading Nylo-Flex construction offers superior durability and shock absorption compared to standard couplings, making it a preferred choice for Beckett burner tune-ups and general boiler maintenance. By facilitating precise alignment, this burner coupling kit minimizes equipment downtime and enhances the overall efficiency of residential and commercial heating system components.
Key Benefits- Universal Compatibility: Includes multiple end piece sizes (1/2", 7/16", 5/16") to fit various burner configurations.
- Vibration Dampening: High-quality Nylo-Flex material absorbs operational shocks, extending the lifespan of the motor and pump.
- Customizable Length: The included 6-inch shaft can be easily trimmed for a precise, custom fit in any application.
- Simplified Identification: Color-coded fittings ensure the correct size is selected quickly during field repairs.
- Professional Grade: Specifically designed to replace Crown KK100 and perform in demanding HVACR environments.
Can this coupling kit be used on Beckett burners?
Yes, the Auburn S85-500 is frequently used in Beckett AF, AFG, and SF series burners and is a standard component in many professional tune-up kits.
Do I need special tools to install the Nyloshaft?
No special tools are required for the connection itself, though a standard cutting tool is needed if you must shorten the 6-inch shaft to fit your specific motor-to-pump gap.
What is the benefit of Nylo-Flex over standard rubber couplings?
Nylo-Flex provides a more rigid, yet flexible connection that better resists the oils and heat found in burner housings while offering superior torque transmission.
