Flexible rubber couplings connect two pipes or filtration elements without the need for glue. They are tightened with stainless steel hose clamps and are easily removed, which simplifies maintenance and system modifications. They also absorb minor misalignments and pump vibrations.
Straight sleeves: for connecting two pipes of the same diameter (Koi Pro from 40 to 110 mm).
Reducers: for connecting pipes of different diameters, for example 110/63 or 135/110 mm.
Elbows, tees, and end caps: for changing direction, creating a branch, or closing an outlet.
Measure the actual outer diameter of the pipes to be connected before choosing: this is what determines the coupling size. The brands available are Koi Pro, Fluidra, and Aquaforte.
