Welcome to the BOSS Sealing Knowledge Base — a practical library of professional sealing know-how, written by our engineers. Here we share technical guides and field experience covering o-rings and hydraulic & pneumatic seals: material selection and comparison (NBR, FKM, EPDM, HNBR, silicone, PU, FFKM, FEP/PFA, PTFE, PEEK), seal design and groove dimensions, installation best practices, failure analysis, and international manufacturing standards such as ISO 3601, AS568 and JIS B 2401.
Whether you are an engineer specifying seals for hydraulic cylinders, a purchasing manager comparing encapsulated o-rings and spring energized seals, or a maintenance technician troubleshooting leaks, you will find clear, experience-based answers here. All articles are based on real production and application cases from our factory.

From explosive decompression to sour gas, amines, steam and thermal cycling: eight oilfield seal challenges with the compounds and qualification standards that pass.
PEEK matches metal on strength and temperature and beats it on corrosion, weight and friction. The numbers, the filled grades, and where metal still wins.
FEP and PFA jacket limits, silicone vs FKM cores, the chemical compatibility map, four jacket failure modes and the gland rules that keep encapsulated O-rings sealing.
