Perlatorschlüssel M24_SW22 / Schlüssel für Strahlregler,Luftsprudler, aerator, jet regulator

thingiverse

Suitable for all standard aerators with thread M24 and wrench size WS22 (also called jet regulator, perlator, jet former, outlet filter). The outside diameter is approximately 60 mm. I believe it's a reasonable size and ergonomic shape for optimal handling. I designed this aerator key for easy assembly and disassembly of aerators (for example, for regular cleaning or replacement). Tightening with conventional metal tools causes damage to the chrome-plated surface of the aerators, as well as cracks and flaking of the chrome coating. The damage often occurs after a few months. With a plastic key like this, there are no more problems. Just a slight tightening of the aerators with approximately 2 Nm is sufficient for a tight seal (unfortunately not measurable with the part - but similar to a bottle closure that is still easy to open for children). If you regularly have very tight aerators, you should probably print in PETG, PLA is sufficient for normal users. Two versions are available for download: Variant 1: Perlatorschlüssel_M24-SW22 (Standard) Variant 2: Perlatorschlüssel_M24-SW22_lower-tolerance (if your material shrinkage is less than 0.3mm) Update from 04-2020: The wrench size on the inside diameter was reduced by 3 mm and provided with a minimal chamfer (for easy insertion). This change enables the operator to push the aerator key further onto the aerator. This is in response to different and manufacturer-specific aerator forms. As before, the aerator key is available in two versions (normal & lower-tolerance). The previous versions work in most cases, so these are still available for download.

I have not received any consideration for this from any of the brand owners / institutions or organizations and this should also be "no advertising" for the brands / institutions or organizations listed here.
