In the era of rapid information dissemination, foreign importers often meet financial losses due to email hacking when conducting transactions. So, how can we ensure that funds remain secure? I will now begin with a real case that happened within our company.

The incident took place in 2014 when both our CEO's email and the email of a hydraulic fittings importer from the United States were compromised and monitored by hackers. This occurred precisely when the customer needed to make a payment for the goods. The customer sent us a message via WeChat requesting our account information once again. However, our CEO did not have any account information saved on her phone. Consequently, upon returning to the office, she sent the company's account details to the customer via email. As you can imagine, the email did not reach the customer's mailbox smoothly; instead, hackers intercepted it midway. They then sent a fraudulent email to the customer, posing as our company. The email informed the customer that we had registered an offshore account overseas and instructed them to transfer the payment to this new account. The customer received the email, arranged for the payment, and also informed us via WeChat that the payment was made, asking us to confirm upon receipt. We responded that we would monitor the payment's arrival.

At that point, neither party suspected any fraud. They continued to discuss arrangements for a meeting in Shanghai. Unbeknownst to them, the hacker was aware of this plan and immediately sent an email in the customer's name, informing us that the meeting might be postponed and suggesting that we remain at the factory instead of going to Shanghai.

Fortunately, due to our ongoing communication with the customer via WeChat, we stuck to the original plan and traveled to Shanghai. After successfully meeting the customer, they asked again about the payment. We informed them that there might be a slight delay and speculated that the payment could come through later that night. Subsequently, both parties discussed further collaboration. To expand the partnership, we mentioned that we were considering using a trade credit insurance from China CITIC Bank, and our company name would be changed to "Ningbo Ningji Yuli Fluid Equipment Co., Ltd.", when the customer saw this new company name, they immediately became suspicious and asked, "Why is the company name different from the account information you emailed me?"

It was only at this point that both parties started to suspect the possibility of being scammed by hackers. They began reviewing their email exchanges and confirmed that both sides had fallen victim to email hacking. The hackers had created an email address remarkably similar to our CEO's email, intercepting our emails while also sending emails to the customer from a fraudulent account. This led to the unfortunate event of the customer transferring the payment to the hacker's account. Immediately, we contacted the Ningbo Bank and explained the situation. The bank assured us that they would contact the U.S. bank to verify the status of the fund transfer.

After an anxious night of waiting, the Ningbo Bank informed us that luckily, the funds had only reached the head office of the fraudulent bank and hadn't been transferred to the hacker's account. Thus, the funds had been successfully intercepted, and no financial loss had occurred.

This is how the incident unfolded. After experiencing this real case of fraud, our company provided the following three recommendations for hydraulic fittings wholesalers to safeguard their funds:

1.Regularly change email passwords to reduce the risk of hacking.

2.When replying to emails, carefully verify the recipient's email address, preferably by typing it anew.

3.When receiving emails about changes to supplier account information, always confirm the authenticity and accuracy of the remittance details through video calls, Tencent meetings, or face-to-face communication.

This article will explore the tips and guidelines for the proper installation and maintenance of SAE 4 hydraulic fittings.
Installation of SAE 4 hydraulic fittings should always be done with precision and care to ensure a leak-free and reliable connection. The first step is to clean the fitting ports and hoses thoroughly. Any debris or contaminants can compromise the integrity of the connection. It is recommended to use a lint-free cloth and a suitable cleaning agent to achieve optimum cleanliness.
Next, it is essential to inspect the fittings and hoses for any signs of damage or wear. Any fittings with damaged threads, dents, or corrosion should be replaced immediately to prevent leaks or system failure. Additionally, ensure that the hose has the correct length and diameter for the application, as using an incorrect hose size can lead to flow restrictions or pressure drops.
Before installation, apply a thin layer of compatible lubricant or thread sealant on the fitting threads. This will facilitate the tightening process and create a better seal. It is essential to use lubricants or sealants recommended by the manufacturer to avoid any chemical incompatibilities that could compromise the hydraulic system's performance.
When connecting the fittings, ensure that the threads align correctly. Cross-threading can damage both the fitting and the port, leading to leaks. Start by hand tightening the fitting to avoid any misalignment or damage. Once hand-tightened, use a suitable wrench to tighten the fitting to the recommended torque value provided by the manufacturer. Over-tightening can also cause leaks or damage the fittings, so it is crucial to follow the manufacturer's instructions.
After installation, it is essential to inspect the system for any leaks. Leaks can lead to a loss of hydraulic fluid, decreased performance, and potential safety hazards. Run the system and carefully check all connections to ensure there are no leaks. If any leaks are detected, tighten the fittings slightly or replace any damaged parts.
Regular maintenance is essential to ensure the optimum performance and longevity of SAE 4 hydraulic fittings. A routine inspection of the fittings, hoses, and connections should be conducted to identify any signs of wear, damage, or leaks. Any issues should be addressed promptly to prevent further damage or system failure.
It is recommended to have a preventative maintenance schedule that includes regular cleaning, lubrication, and inspection. This will help ensure the fittings remain in proper working condition and reduce the risk of unexpected failures.
In conclusion, SAE 4 hydraulic fittings are versatile components that play a crucial role in hydraulic systems. Proper installation and maintenance are essential for maximizing their efficiency and reliability. By following the tips and guidelines outlined in this article, users can ensure leak-free connections and prolong the lifespan of their hydraulic systems. Remember to always refer to the manufacturer's instructions and recommendations for specific installation and maintenance procedures.
