Tap Magician Valve Cartridge Spline Gauge teeth Measuring size Finder Plumbers

Really useful tool to measure the diameter and number of teeth on a tap cartridge. Saves time from trying to count the teeth and ensure you purchase the correct replacement part. Came with a wallet to store it in and a useful card showing you how to take the various measurements to make sure you get the right spare part. Good price and looks well made.

Sturdy and very well made. Very useful if you don’t want to go crazy counting those little teeth some other way: this one gets the job done, saving time and potentially money. A very good tool…

Bit pricey at £15 but this will last forever as its strong ie won't bend if you drop it or have it in your pocket.

With modern quarter turn taps having so many differences (WHY I ASK??) this tool helps identify the right spare valve.

This is a great products trusted widely. It does what its supposed to do.

This is a handy piece of kit, i work as a handyman and im not a plumber but i come across many different types of ceramic disc valve types that need changing, many have had handles forced onto the splines but with this piece of kit i can identify the spline count before removing the valve and order a replacement or check stock before removing and going to a merchants. Saving me time and money.

Impressed with prompt delivery which was very quick, nice size complete with wallet to keep it in. Glad I got it as diameter I believed was correct, after using gauge, found that it wasn't. when fitting gauge over some splines some play/movement noticed but could be down to cartridge, as some are not as well made as they used to be. A handy little tool nonetheless.

Worth getting one only if you do a lot of older taps
