AstralPool - Plastic Bulkhead Light Replacement O-Ring (Position 5) - SP-03-0038

AstralPool – Plastic Bulkhead Light Replacement O-Ring (Position 5)

This is the genuine AstralPool replacement O-ring (position 5 in the official Fluidra exploded view) for the AstralPool Plastic Bulkhead Light (33708IP74). It forms the critical watertight seal between the light body and the pool wall, preventing water ingress and protecting both the fitting and the pool structure. Replacing a worn or damaged O-ring is the first step in resolving leaks around your bulkhead light.

Compatibility

This O-ring is designed exclusively for the AstralPool Plastic Bulkhead Light with parent SKU 33708IP74. It is not a universal part — always verify your light’s model number before ordering to ensure a correct, leak-free fit. Refer to position 5 on the official Fluidra exploded view diagram for your model.

Why Genuine Matters

Genuine AstralPool O-rings are manufactured to precise dimensional and material tolerances, ensuring full compatibility with the original sealing groove and long-term resistance to pool water chemicals, UV exposure, and temperature fluctuations. Third-party substitutes may vary in size or compound, risking premature failure and water damage.

Installation

Before fitting, clean the sealing groove thoroughly to remove any debris, calcium deposits, or remnants of the old O-ring. Apply a thin smear of silicone-based lubricant to the new O-ring before seating it — never use petroleum-based grease, which can swell and degrade rubber seals. If in doubt, consult a qualified pool technician for installation.
