Att.: We saw some online sellers is selling this product to be stainless steel, looks stronger which is very dangerous!
This is the pressure relief valve of the entire cylinder because the pressure relief valve of the Mercury series is not designed with the spring steel ball and is not adjustable. If the pressure is too high during the lifting of your boat, this part will be ejected or broken, and the excessive pressure inside the cylinder will be discharged. If this thing becomes a product that will not break, it will block the pressure relief channel of the cylinder, causing the entire cylinder to easily crack.
I really don't understand whether this seemingly balanced design is going to cause greater losses to customers.We respect the choice of our customers, but I think we still have to tell the users of the potential risks, which is responsible for them.
