A new customer in Mexico, the customer asked for a Parker finite 4CJDK filter element, which is a natural gas filter element. The customer provides the picture and size of the filter element when inquiring. The customer previously used the original product Parker finite 4CJDK. Communicate with the customer whether it is possible to send samples, we check the structure of the filter element, and then produce it to the customer, and the customer agrees to send the sample. We received the sample and found that we need open mould to produce. We inform the customer that we need to open mould for production, but our company will bear the mould cost. The customer agrees that we start the production for Parker finite 4CJDK, and now Parker finite 4CJDK has been produced for the customer, which is exactly the same as the customer's sample, and the product has been sent to the customer. Parker finite 4CJDK, is our superior product, if you have any requirements, please feel free to contact us.
