The Hoffman 99070035SP is a capacitor tube cap designed for use with M52 threaded connections. This component serves as a protective cover or end cap for capacitor tubes, ensuring secure sealing and protection of internal components within electrical enclosure thermal management systems. It is engineered to withstand industrial environments while maintaining compatibility with standard M52 mounting interfaces.
Verify the exact thread specification matches M52 requirements before procurement. Confirm compatibility with existing capacitor tube assemblies in your specific enclosure model. Check for any environmental rating requirements such as IP65 or NEMA 4X if used in harsh conditions. Ensure the material composition meets your corrosion resistance needs. Cross-reference with nVent Hoffman official documentation to confirm current availability and part status.
Select this part when replacing damaged or missing caps on M52 capacitor tubes. Ensure the replacement maintains the same dimensional tolerances as the original component. Consider environmental factors such as temperature extremes or chemical exposure that may affect cap longevity. Verify that the new cap aligns with existing thermal management system design specifications.
This component belongs to Hoffman's line of thermal management accessories for electrical enclosures. It supports the broader ecosystem of cooling and heating solutions provided by nVent Hoffman for industrial control panels and machinery applications.
Direct substitute: 99070035SP (same part number). Verify thread pitch and diameter match exactly. No alternative part numbers are publicly confirmed as direct replacements.

Select power transformers by input frequency, secondary VA, rectifier load, isolation, regulation and inrush. Build a clearer specification for your next RFQ.
