Diking R134A R12 A/C HVAC Air Conditioner Schrader Valve Stem Core Remover Tool (Remover Tool)

Decent enough as long as you don't over-tighten with them. I bought a second set because a mouth breather I work with broke the tab off one of them. They work good and I have used them for many years before the borrowed one got broke.

Product met my expectations. Good turn around time.

Only used the large red stem removal tool for the high side of a Ford Ranger 3.0 XLT. Stem so tight had to use pliers, finally got loose but stem wouldn't come out. Tool WORKED WELL but stem broke off inside.

Worked as it should

Very nice set has every size you will need

Good variety of tools to remove the tamper-resistant caps on shraeder valves on condensers. Different sizes, one is bound to fit. Reasonable price for a necessary tool.

useful

These tools is not for the professional who does heavy duty work. but is quite adequate for the DIY's who want to work on cars and smaller system.

A/c valve stem removal tools found here at an excellent price than most suppliers. I use them often and haven’t had any issues with them.

DAC

We are using it daily at the County Public Works shop where we have over 50 vehicles with air conditioning and we've had a record heat wave

Could not stamp up to the force needed to properly tighten the a/c valve.
