Anti-Scald Device - TAFR

Fitting Guide

The most basic thing you need to know about your faucet in order to add an Anti-Scalding device is the threading - either male or female. If your faucet has threads on the outside, it is male threaded - which means you need to use just the FEMALE threaded component. Conversely, if your faucet has threads on the inside, it is female threaded and you'll need to use the included MALE threaded adapter. Our anti-scald devices work on both MALE and FEMALE faucets and pipes!

Our Anti-Scald devices work on "REGULAR" size plumbing. Typical "REGULAR" size for a faucet aerator is 15/16" male threaded or 55/64" female threaded, while "Junior" size is 13/16" male threaded or 3/4" female threaded. Some faucets use a smaller "Tom Thumb" metric-size aerator, which is M18x1 male threaded or M16x1 female threaded. If your faucet or pipe is not "REGULAR" you will need an additional adapter. But wait! Before you get out your tape measure, there's a very easy way to tell what size your plumbing is.

First, take the existing aerator off your faucet or shower head off the stem - usually these just unscrew, although you may need a wrench if it's on there tight. Then grab some spare change from the couch or your rainy day jar, specifically a quarter, a nickel, and a dime. Place the coins over the aerator/connector. If your current aerator/connection is about the size of a quarter, you have a "REGULAR" sized fixture!

If it's about the size of a nickel, you have a "Junior" size aerator. If your aerator is approximately the size of a dime, you have a "Tom Thumb" size aerator. Both "Junior" and Tom Thumb" sizes will need an adapter that you can purchase from the hardware store.
