🐟 Enhance Your Fish Pond Air Pump with FarBoat's 10Pcs Aquarium Diaphragm Silicone Cup Replacements Review

Just so everyone knows these boots fit great and work with the Tetra Whisper 100 Air Pump They are made from silicone which is a much better material than EPDM rubber. A simple and inexpensive way to fix a punctured shoe.

So the diaphragms appear to be fine but are not. Doesn't fit my pump. I have a Whisper AP300 and this part has a burr on the inside edge. Not in this part. Please take apart your pump before ordering to make sure it fits your pump.

This diaphragm has the correct ID and OD but is 2mm larger than the original parts. The bezel also doesn't have a notch on the inner diameter, which is meant to match the look of the white plastic camera that holds it in place. I tried removing the extra nut to make up for the 2mm height difference, but that still left the magnet in the wrong position for maximum pumping action. The video shows the original screen on the left and this element on the right. While it fits, it doesn't pump as much
