What Is a V-Stack Seal Assembly? A V-Stack Seal Assembly—often referred to as a seal stack or V-packing stack—is a combination of multiple sealing elements arranged in a stacked configuration. Each element features a chevron-shaped profile, allowing the stack to energize under pressure and create a reliable, long-lasting seal. Because the individual rings flex and adapt to pressure cha...
In hydraulic and pneumatic seals, main seals such as O-rings receive much attention, but their performance relies on an often overlooked component: the back up ring. What is a Back up Ring? A back up ring is a rigid ring installed next to the seal to prevent it from being squeezed into the metal gap under high pressure. Back up rings are essential when system pressu...
In the oil and gas industry, ensuring a secure seal in wellhead equipment is crucial for safety and preventing leaks. P-seals provide a high-performance solution designed to withstand extreme conditions, making them essential in wellhead systems. So, what exactly is a P-seal, and why is it so important? What is a P-Seal? P seal is constructed from an elastomer with back up rings for anti-ex...
