ASCO 323-457 Rebuild Kit

The ASCO 323-457 Rebuild Kit is a comprehensive maintenance solution engineered specifically for ASCO 8238 series solenoid valves. Designed for pilot-operated brass valve bodies, this ASCO valve repair kit includes critical internal components such as the solenoid core assembly, bonnet gasket, body gasket, core spring, and plug nut core tube sub-assembly. Utilizing a genuine ASCO replacement part ensures that the valve maintains its original UL listed specifications and pressure ratings, preventing internal bypass or failure in high-demand HVAC and industrial combustion applications. By replacing worn elastomeric seals and mechanical springs, technicians can restore bubble-tight shutoff and responsive actuation without the cost of a full valve body replacement. This kit is compatible with ASCO 8238 AC/DC configurations, including models SC8238T402 and SC8238T405, and serves as a direct cross-reference for Grainger part number 4EKT8.

Common Questions

What valves is the ASCO 323-457 compatible with?
This rebuild kit is specifically designed for the ASCO 8238 series, including common pilot-operated models like the SC8238T402 and SC8238T405.

Does this kit include the solenoid coil?
No, the 323-457 kit focuses on the internal mechanical and sealing components. If you have an electrical failure, the solenoid coil must be purchased separately.

When should I rebuild my ASCO solenoid valve?
We recommend a rebuild if you notice sluggish opening/closing, audible internal leaks, or as part of a scheduled annual maintenance program to prevent downtime in critical combustion loops.
