1. Price: Chinese copies are generally much cheaper (especially direct from China). MAC have strict/structured pricing so considerably cheaper products are very unlikely to be genuine.
  2. Location: Every cheap valve from China that we have seen has not been genuine.
  3. Retail packaging: Most of the fake MAC valves are retail boxed as packaging has also been copied.
  4. Internal packaging / Plastic bag: The Chinese internal packaging often has spelling mistakes. We have shown an example of this in our images.
  5. Date of manufacture: Chinese copies generally have older dates of manufacture printed on the rear like 2013, 2014, 2015 etc. We have shown an example of this in our images.
  6. Embossed letter “P”: We have noticed that nearly all of the Chinese fake valves have the letter “P” cast onto the front of the valve, so this can often be a very clear initial indication. We have shown an example of this in our images.
  7. Brass Muffler Fittings: We have noticed that nearly all of the Chinese fake valves are supplied with a brass coloured exhaust/muffler, so once again this can often be a very clear initial indication as these are not required and don’t really serve any purpose. We have shown an example of this in our images.
  8. Coil gasket: It is quite common for the Chinese copied valves to be missing the rubber gasket between the coil/valve bodies. This results in water ingress and premature failure amongst other possible issues as a direct result. We have shown an example of this in our images.
  9. Internal hammer guide sleeve: It is also quite common for the Chinese copied valves to be missing the internal hammer guide sleeve. This results in inconsistent operation and premature failure amongst other possible issues as a direct result. We have shown an example of this in our images.
  10. Top Screws/screw in cap: Chinese copies generally use poor quality (often zinc yellow) coil fixing screws, so again this can often be a very clear initial indication. Also the manual actuation cap on top of the valve is often visually of poor quality and commonly loose (original caps are thread locked to stop them working loose in operation). We have shown an example of this in our images.
