Caps and plugs are used to close the ends of pipes to stop fluid flow. Caps cover the external pipe end, while plugs seal internal pipe threads. These fittings are essential for pipeline termination, pressure testing, and future expansion provisions. Caps and plugs protect pipelines from contamination and damage. They are used across industrial, plumbing, and utility piping systems. Designed to withstand pressure, they ensure system safety and reliability. These fittings support both temporary and permanent closures.
