端盖/堵头

An end cap or plug is a precision-engineered component designed to seal the terminal ends of spray manifold systems, preventing fluid leakage, maintaining system pressure, and protecting internal components from contamination. It serves as a critical closure element in fluid distribution systems where multiple spray nozzles are mounted along a manifold pipe.

The end cap/plug creates a mechanical seal at the manifold's end through threaded, welded, or compression fitting methods. It withstands internal fluid pressure by distributing stress evenly across its structure, while sealing surfaces prevent leakage through gaskets, O-rings, or metal-to-metal contact. In spray systems, it ensures uniform pressure distribution along the manifold by providing a closed boundary condition.
