Discover the most common hydraulic seals—rod seals, piston seals, wipers, O-rings, and more. Learn their key functions and how to choose the right one for your system.

Introduction: The Unsung Heroes of High-Pressure Hydraulics In the world of fluid power, hydraulic V-packing seals are essential components for ensuring the reliability and efficiency of hydraulic systems. Also known as v pack seals, v-ring packing seals, or chevron v packing seals, these multi-lip seals are specifically engineered to withstand the demanding conditions of high pressure, frequent cycling, and harsh environments. This article provides a comprehensive overview of their working...

Explore the function of skeleton oil seals—also known as seal skeletons or skeleton seals—and learn how the metal skeleton supports the rubber lip to maintain a precise oil film, preventing leaks and contaminants. This concise guide covers key components, sealing principles, and application tips for optimal performance.

In the semiconductor industry, where cleanroom integrity and uptime are mission-critical, selecting the right sealing materials can directly impact yield, process stability, and maintenance intervals. FFKM (perfluoroelastomer) O-rings are the gold standard for plasma etch and CVD (Chemical Vapor Deposition) chambers due to their unmatched chemical resistance and high-temperature capabilities. However, not all FFKM seals are created equal. This guide walks you through how to choose the optimal...

The encapsulated O rings are made of silicone rubber or fluororubber core and wrapped in an FEP or PFA outer shell. This combination of a rubber's flexibility with a PTFE (Teflon) resistance to chemicals makes for strong, long-lasting O-rings. Encapsulated O rings can handle extreme temperatures, chemicals, and wear and tear very well.

Spring Energized Seals are made up of U-shaped sealing rings made from PTFE and springs that resist corrosion. The metal spring provides the initial sealing force at low pressure and zero pressure. As system pressure rises, the sealing lip pushes out. It gently presses against the sealed surface. This keeps the sealing interface in contact, creating an excellent seal. It can be widely used in the chemical, pharmaceutical, and food industries.

Discover how wear rings enhance hydraulic system performance by preventing metal contact, reducing friction, and extending seal life.​
