AstralPool - 2" Fitting with O-Ring (Position 6) - 4404040104

AstralPool – 2″ Fitting with O-Ring (Position 6)

This genuine AstralPool 2-inch fitting with O-ring is an OEM replacement connection component used in AstralPool pool filtration systems. Supplied as a matched set — the threaded union fitting and its sealing O-ring together — it restores a leak-free hydraulic connection at the filter body. It corresponds to position 6 in the official Fluidra exploded-view diagram for the Pool Spare Parts Catalogue (parent 523).

Compatibility

This part is designed for AstralPool pool filtration assemblies that reference parent catalogue 523 and use a 2-inch (2″) port connection at exploded-view position 6. Always cross-reference the exploded diagram for your specific filter model before ordering to confirm fitment. If in doubt, quote SKU 4404040104 to your AstralPool distributor.

Why Genuine Matters

As an authentic Fluidra/AstralPool part, this fitting is manufactured to OEM dimensional tolerances, ensuring the O-ring seats correctly and holds a watertight seal under normal pool operating pressures. Aftermarket alternatives may differ in thread pitch or O-ring cross-section, risking slow leaks or premature seal failure — a risk easily avoided by choosing the original part.

Installation

Hand-tighten the fitting into the filter port, then snug firmly — avoid over-torquing, which can distort the O-ring. Apply a thin coat of silicone-based lubricant to the O-ring before assembly to ease installation and extend seal life. Inspect the mating surface for scoring or debris before fitting the new part.
