Pentair CLN/CLR/DE Compression Spring (178616Z)

Description

A small washer can make a big difference inside a DE filter service routine. This polyethylene replacement washer is intended for RegenX assemblies where spacing, fastening support, and smooth movement need to be restored without replacing larger filter components. Useful during rebuilds when the existing washer is worn, cracked, missing, or flattened from repeated service.

Choose this replacement when you want a clean, part-specific repair rather than forcing a workaround that can create leaks, fit issues, or recurring service calls. Always match the part number, equipment series, horsepower, plumbing size, color, or application details before installation.

• Supports cleaner DE filter service and internal component refreshes
• Helpful during seasonal maintenance or filter rebuild work
• Replaces worn hardware that can affect sealing, alignment, or flow
• Built for compatible Hayward Pool Products equipment applications
