Astralpool Lid Assembly - CTX, Viron XT

Astralpool Lid Assembly - CTX, Viron XT SP40089

This is the genuine Astralpool complete lid assembly, part number SP40089 — the clear top, locking ring and o-ring together. It is the lid you look through to check the basket. Genuine OEM, not cheap generic — the aftermarket clear tops craze and yellow far faster.

• Physically Stocked, unlike most "drop-shipping" websites.
• Shipped from VIC, NSW, WA, QLD

Whole Lid — or Just the O-Ring?

This listing is the complete lid. If your clear top is fine and only the seal has perished, you can save money with the o-ring alone:

• The clear lid is cracked, crazed or cloudy — this part, the complete assembly SP40089.
• Only the seal has perished — the lid o-ring alone (70006).

Fitting Tip

The lid is designed to be hand-tight only — do not use tools. Clean the o-ring seat before fitting, since debris on the seat lets air into the suction side and stops the pump priming. Astralpool recommends checking and greasing the lid seal every three months.
