## Questions & Answers

**Q: Where is this manufactured?**
A: Anyone know where this kits manufactured today? 
 
Fwiw:
  Taiwan doesn't bother me any because I know some of the highest grade Torque wrenches, Levels, measuring tools etc.. have all been made there for many yrs. 
 Most items I've compared from Taiwan vs China, their quality standards are night and day difference. 
 Idk why its such a difference between the two but it certainly is a big difference.

**Q: Does the Mityvac 5530 come with both metric and SAE fittings or just one fitting standard?  If one fitting standard which one?  Adapters available?**
A: I have used this set on Cars, Motorcycles and Lawn mower/tractors. Comes with M10, M12, M14 to M18(Long reach) Adapters, Pressure Hold Adapter, 144 Long and Short Threads in a couple of different lengths. 18mm Short reach. Field service kit. Gauge, case. What are you trying to check the compression on??

**Q: Does this have a 12mm long reach hose/adapter?**
A: It has a 12mm adapter that attachs to the hose. 14 mm short-thread adapter with 6 1/2" (165 mm) and 12" (305 mm) long hoses 14 mm long-thread adapter with 12" (305 mm) long hose 18 mm short-thread adapter with 12" (305 mm) long hose 14 mm short-thread x 18 mm long-thread adapter 10 mm thread small engine adapter 12 mm thread small engine adapter

**Q: Is this easy enough to use in a somewhat recessed spark plug hole? I have a yamaha F20 4 stroke whos spark plug hole has ~2in recess.**
A: Yes, it's easy to use. The hose is stiff enough that you can put it in deep spark plug holes and tighten it. Just like you'd be using a long extension and socket.

## Customer Reviews

### ⭐⭐⭐⭐⭐ High Quality, Accurate
*by S***Z on January 5, 2025*

Very nice piece of equipment. A must for small engine (as well as automotive) diagnostic work.This unit has Schrader valves on all the hoses, where they screw into the spark plug hole. This gives a much more accurate reading.Also comes with spare parts such as o-rings and Schrader inserts.

### ⭐⭐⭐⭐⭐ Nice Quality
*by R***G on July 31, 2025*

Used on several engines and works great. No leaks. Can’t guarantee accuracy but it gives constant readings to help diagnose engine issues. I recommend it.

### ⭐⭐⭐⭐⭐ Great product!
*by D***S on July 5, 2025*
