Waterpik Aquarius WP-660 or Ultra WF-100
JT-100E Precision Tip
This countertop tip was previously called Classic Jet. Match JT-100E on the pack; Waterpik excludes Sidekick, Sonic-Fusion, Whitening and Classic flossers from this tip family.

JT-450E Precision Handheld Cordless Tip
Use the handheld cordless tip code JT-450E. The familiar Classic Jet wording also appeared on this tip, so the product code is the useful distinction when comparing packs.

Find the right replacement
Find your model’s replacement
Enter the brand and model, or add a photo of the product label.
Fast rule: the exact model, cartridge or part code beats appearance. If the listing does not clearly name what you own, do not force the match.
Find the flosser model
Use the model number from the base or handle and search it with “replacement tips.” Brand-level compatibility can be too broad, especially across cordless and countertop generations.
Compare the insertion stem, locking groove and release mechanism with the tip you are replacing.
Choose the tip purpose after fit
Compatible systems may offer standard jet, orthodontic, plaque-control or other specialized tips. Select the style that matches your intended use after confirming the connector.
If dental treatment or a medical condition affects which tip you should use, follow your dental professional and device-manufacturer guidance.
Keep personal tips identifiable
Multi-user households can use color rings or other manufacturer-provided identifiers when available. Do not share a used tip between people.
Store spare tips clean and protected until needed.
