About This Item
The Pentair Compression Spring (178616Z) is the OEM replacement spring for the EasyClean, Quad D.E., and Clean & Clear Plus filter series — maintaining proper internal pressure and component seating within the filter assembly.
⚠️ IMPORTANT: VERSION QUALIFIER — CLEAN & CLEAR PLUS FILTERS
For Clean & Clear Plus filters, this spring applies to units manufactured after November 1998. Check your filter's manufacture date before ordering.
The compression spring maintains consistent tension on internal filter components, ensuring proper seating and seal engagement during operation. A fatigued or broken spring can result in improper component alignment, reduced filtration efficiency, or internal bypass. Replacing this spring at the first sign of wear restores correct assembly tension and extends the service life of surrounding components.

Pro Tip
When servicing your filter, inspect the spring for visible deformation, corrosion, or loss of tension before reassembly. If the spring no longer holds its shape or sits flat at rest, replace it — a compromised spring will not maintain proper component seating regardless of how the filter is reassembled. For Clean & Clear Plus owners, confirm your filter's manufacture date (stamped on the tank label) is after November 1998 before ordering this part.
