In October 2025, clients from Austria and Ireland visited FBU Sealing Technology (Suzhou) Co., Ltd. for an on-site inspection, focusing on the selection and cooperation of sealing solutions for extreme working conditions. With basic chemicals and oil refining as their core industries, the production equipment in both regions frequently operates under conditions such as high temperature, high pressure and pressure fluctuations. The primary demand of the clients from the two countries during this visit was to find sealing products that are adaptable to local working conditions, combine reliability and cost-effectiveness, and address the challenges of leakage risks and compliance.

The APOG-API Specific Double Cartridge Mechanical Seal developed by FBU Sealing Technology (Suzhou) Co., Ltd. was the key product showcased during the client visit. As a high-end mechanical seal complying with the API 682 standard, its balanced integrated ring design can effectively resist pressure fluctuations in the seal chamber; the seal ring and sleeve are made of high-pressure and high-temperature resistant alloy materials, capable of withstanding temperatures below 200℃ and pressures below 40bar, accurately matching the equipment needs of local industrial sectors.

As a leading domestic technology-oriented enterprise, FBU Sealing has established a full-process quality control system. Each mechanical seal undergoes multiple rigorous tests including working condition simulation and leakage rate testing. It is believed that with its excellent working condition adaptability and high cost-performance ratio, APOG will become the preferred choice for chemical clients in seal selection.
