🧰 Not sure if the 5 adaptors included with the HydraPure 360™ will fit?
This add-on kit covers the rare, recessed, and hard-to-fit faucets — and pairs perfectly with the Grip & Twist™ Wrench
.
Because not every faucet follows the rules.
The Uncommon Fit Kit™ is a 6-piece specialty adaptor set created for those tricky faucet types that don’t play nice with the standard fittings that come with your HydraPure 360™. If your faucet has recessed internal threads, a metric fitting, or a size that seems just a little off — this kit was made for you.
We recommend inspecting or measuring your faucet’s aerator before installation. If the opening is smaller than 20 mm or larger than 27 mm, or if your aerator is recessed and threads are on the inside of the faucet, this kit will likely assist with getting the proper fit.
---------------------------------------------------------------------------------------
Your HydraPure 360™ already comes with 5 standard-size adaptors, including a G1/2" female fitting. This kit adds the G1/2" male version (for recessed internal threads) — same size, opposite thread direction.
