FROK Suction Cap for Submersible LED (4pcs/Pkt)

FROK Suction Cap for Submersible LED (4pcs/Pkt)

Keeping submersible LEDs secure with FROK replacement suction caps

Suction caps are the small part that always seems to perish first. The rubber stiffens and loses grip over time, especially in our warm tanks where heat and constant immersion age the material faster. This four-pack lets you refresh the mounts on a submersible FROK LED rather than retiring a perfectly good light because one cup stopped holding. Keeping a spare set in the drawer saves a frustrating evening when a strip suddenly drops behind the rockwork.

For the best hold, clean the glass thoroughly before fitting; algae film and oily residue are the usual reasons a cup pops off mid-week. Press firmly to expel trapped air and water, and let a new cap warm slightly in your hand so the rubber conforms to the glass. If a cup still wanders, reposition it away from a high-flow return where constant pressure works it loose over days.

You will find compatible fixtures across our lighting range. If your submersible bar mounts awkwardly on a small tank, our best clip-on lights for nano tanks and best planted-tank LED guides cover sturdier mounting alternatives.
