PQY 14 6mm Non Return One Way Fuel Check Valve Aluminium Alloy Petrol Diesel

The PQY 18" 4mm Non Return One Way Fuel Check Valve is a product that has received mixed feedback from customers. While some users have found it to be a reliable and effective solution for their fuel check valve needs, others have experienced issues such as leakage and a lack of durability. One customer found that the check valve leaked as soon as they installed it, but were able to resolve the issue by replacing the undersized sealing O-ring with a larger one. Another user expressed satisfaction, stating that the part worked great with no problems and was exactly as described. On the other hand, a few customers had negative experiences with the product. One user mentioned that the check valve did not hold up after about an hour of use on their dirt bike, while another mentioned that it leaked and lost the prime in less than 24 hours when used to keep a small pump primed. It is worth noting that there is some confusion and uncertainty regarding the compatibility of this check valve with certain applications. For example, when asked if it is compatible with coolant, the answer was no, as it is made for vacuum and not liquid. The same confusion arises when asked if it works for a vacuum PCV in an automotive setting, to which the answer was no, as it is designed for fluids. Overall, the PQY 18" 4mm Non Return One Way Fuel Check Valve has received mixed feedback from customers. While some have found it to be a reliable solution for their needs, others have experienced issues such as leakage and a lack of durability.
