During the Quality Month campaign in 2025, Xi'an Yuqi upheld the quality philosophy of "Excellence in Details", implementing rigorous standards throughout the entire product lifecycle. Through establishing eight quality checkpoints covering raw material inspection, production process monitoring and finished product testing, the company continuously enhanced the reliability and stability of high-pressure sealed connector products.

1. Requirements for Mechanical Seals Mechanical seals are generally divided into two parts: liquid seals (analysed in this issue) and gas seals (i.e., dry gas seals, which will be specifically summarised and shared later) Liquid seals are mechanical seals specifically designed to seal liquids. In fact, the liquid film between the sealing faces is extremely small - equivalent to twenty millionths of an inch or half a micrometre. This liquid film helps isolate and lubricate the sealing faces.
