Portacool INJS0018K Drain Cap Evaporative Cooler

Product Description

The PORTACOOL INJS0018K is a drain cap designed as a direct replacement component for PORTACOOL evaporative cooling units. This cap seals the drain port on portable evaporative coolers, preventing water leaks and allowing the reservoir to hold water during operation. It is a straightforward service part that HVAC technicians and portable cooling equipment technicians install during routine maintenance or after damage to the original cap. At 7 inches wide and 7 inches tall, it is a compact piece with a precise fit for compatible PORTACOOL units.

This drain cap is suited for portable evaporative cooler service in both residential and commercial applications. PORTACOOL evaporative coolers are commonly deployed in warehouses, job sites, outdoor events, and light commercial spaces where duct-free spot cooling is needed. Replacing a worn or missing drain cap restores the reservoir's ability to hold water, which is essential for consistent evaporative cooling performance.

Installation Notes

Installation is performed by an HVAC technician or qualified service professional familiar with portable evaporative cooling equipment.

Ensure the drain port threads or seating surface are clean and free of debris before seating the new cap. No special tools are typically required for this service task.
