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.

A reseal fails on the bench long before it fails on the machine. Groove inspection, cleanliness targets, installation without cutting the lip, and the test that finds the fault.
The wiper runs dry, meets the dirt first and decides how long the rod seal lasts. ISO 6195 housing types, lip designs, materials and the failures it prevents.
One seals against a moving chrome rod, the other separates two pressurized chambers. How pressure direction, housing standard and gap clearance pick the profile.
