In piping and fitting systems, dead space refers to small internal pockets where flow doesn’t reach. These areas aren’t doing anything useful, and in most cases, they go unnoticed. However, in systems operating at cryogenic or low temperatures, those same pockets can cause significant issues.
The sealing bead forms the metal-to-metal contact that creates a leak-tight seal in VCR-style fittings. This interface must remain clean, undamaged, and properly aligned to function correctly.
Hy-Tech’s Anti-Torque Rings were built to stop that from happening.
Over-tightening is when a gasket is compressed beyond its recommended torque limit during installation. It may happen due to a lack of proper torque-control tools, misunderstanding of the specifications, or the common belief that tighter means better.
