🧰 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.

--------------------------------------------------------------------------------------

Key Features :

 

A 6-piece specialty adaptor set designed to help your HydraPure 360™ fit uncommon or tricky faucet types — including internal threads, oversized heads, and metric sizes not covered by standard adaptors.

 

  • Includes 6 rare-size aerator adaptors for non-standard faucet

 

  • Covers internal threads, oversized fittings, compact and metric sizes

 

  • Made for recessed, tight, or hard-to-fit faucet types

 

  • Expands compatibility beyond the 5 standard adaptorsincluded with HydraPure 360™

 

  • Compatible with select European, Asian, bar, and utility-style faucets

 

  • Best paired with the Grip & Twist™ Wrench for stuck or recessed aerators

 

--------------------------------------------------------------------------------------

 

WHAT’S INCLUDED (6-PIECE ADAPTOR SET):
Adaptor Threads Size (mm) Function
Male 22mm → Male 28mm External 22mm to 28mm Upsize for oversized faucet heads
Male 18mm → Male 22mm External 18mm to 22mm Compact or recessed faucet openings
Male 20mm → Male 22mm External 20mm to 22mm Bar sinks or narrow faucet tips
G1/2” Male → Male 22mm BSP ~21mm to 22mm Recessed, internal-thread (female) faucets

Female 16mm → Male 22mm Internal Snap-In 16mm to 22mm Small internal-thread aerators or unusual inserts

 

If your faucet has a recessed aerator, non-standard size, or snap-in design, the Uncommon Fit Kit™ helps bridge the gap and ensures a smoother fit.
For tight or stuck recessed aerators, pair it with our Grip & Twist™ Universal Aerator Wrench for best results.

Handy little kit to have around. Didn’t even realize there were so many faucet sizes out there until I tried installing my filter.

I thought this kit had the size I needed but that was on me for not measuring or checking the guide first. The brand helped me out and I grabbed the right size adapter on Amazon. Had my filter running in no time.

Used the fit guide and measured before ordering — saw right away I’d need this kit. Saved me a headache and made install super easy.

Ordered the kit thinking both sinks would need it, but only one actually did. The other sink fit the filter perfectly without any adapter. Still glad I had it on hand.

The adapters are solid and feel like good quality. Made the install simple where otherwise it wouldn’t have fit.
