Couplings are essential components in mechanical power transmission systems, connecting shafts between motors, gearboxes, pumps, and other rotating equipment. Selecting the right type of coupling is critical for ensuring reliability, efficiency, and longevity of machinery. Among the various types, rigid couplings and flexible couplings are the most

Rigid couplings are fundamental components in mechanical power transmission, providing a solid connection between shafts and ensuring precise rotational alignment. When selecting rigid couplings, material choice plays a critical role in performance, durability, and efficiency. Among the most common materials used are steel and aluminum, each offeri

This page summarizes key standard developments in 2025–2026 that affect fire-service pipe couplings, gasketed fittings, welded outlets, flexible hose fittings, and related joining systems. It’s written for specifiers, manufacturers, QA/QC engineers, installers, and procurement teams who must keep product design, testing, and project submittals
