Hayward DEX6020BTC Filter Head with Clamp System (Upper Body/Lid Assembly) for DE6020 & SwimClear
The Hayward DEX6020BTC is a complete OEM filter head (upper tank body/lid) with clamp system designed to restore a secure, service-friendly seal between the upper and lower halves of compatible Hayward filters. It’s the go-to replacement when the original head is cracked, warped, leaking at the clamp seam, or no longer seals reliably after years of heat/UV exposure.
Fits / Compatibility
- Hayward Pro-Grid Vertical Grid D.E. Filter: DE6020 (60 sq ft)
- Hayward SwimClear Cartridge Filters: commonly used on C5030 and often listed for C5020 / C5025 (verify by model/parts diagram)
Fit tip: Confirm your filter model from the data label and compare your current head/clamp style before ordering. Filter heads are not universal across Hayward filter families.

- Upper filter head / lid assembly

Installation Notes
- Turn off the pump and relieve filter pressure at the air relief before opening the filter.
- Clean the tank flange and sealing surfaces thoroughly; grit can cause leaks and uneven clamping.
- Seat the tank seal evenly and clamp the head down uniformly—tighten according to the filter’s instructions.
- After restart, bleed air until a steady stream of water flows, then inspect the clamp seam for seepage.

Maintenance Tips
- Never loosen a clamp or open the filter while it is under pressure—always shut off the pump and bleed air first.
- Keep the clamp band and sealing surfaces clean; debris under the clamp or seal is a common cause of leaks.
- Lightly lubricate the tank seal with a silicone-based lubricant (avoid petroleum products) to help prevent pinching and improve sealing.
- If you see repeated seepage at the seam, inspect for flange damage/warping and replace worn seals rather than overtightening the clamp.
