This is the genuine AstralPool replacement cable packing gland (cable gland connector) for the Extra-Flat underwater pool light fitted to concrete pools, models 21626 and 35666. It forms the watertight seal around the electrical cable where it exits the light body, preventing water ingress into the fitting and protecting both the installation and the swimmer. Sourced directly from Fluidra, this is the exact OEM component specified in the official exploded-view diagram at position 13.<\/p>\n
This packing gland is designed exclusively for the AstralPool Extra-Flat Light for concrete pools, parent SKU 35666 (also listed alongside model 21626). It corresponds to position 13 in the official Fluidra parts breakdown. Always cross-reference your light’s model number and exploded-view diagram before ordering to confirm fitment.<\/p>\n
A correctly rated, watertight cable gland is a safety-critical component in any underwater lighting installation. Using a genuine AstralPool part ensures the correct thread profile, sealing material, and dimensional tolerances are maintained \u2014 keeping the fitting waterproof and compliant with the original design specification. Aftermarket alternatives may not seal reliably under pool water pressure or temperature cycling.<\/p>\n
The packing gland must be fully tightened before the luminaire is submerged \u2014 as stated in AstralPool’s official installation manual. We recommend this work is carried out by a qualified electrician or pool technician, as it involves a mains-adjacent, permanently submerged electrical component. Ensure the pool light is isolated from its power supply before beginning any work.<\/p>","protected":false},"excerpt":{"rendered":"
