End Cap/Plug: Temperature Range -40°C to 200°C

Component Specifications

Definition

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.

Working Principle

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.

Materials

Stainless steel (AISI 304/316), brass (C36000), aluminum (6061-T6), engineered plastics (PTFE, PEEK, Nylon), with corrosion-resistant coatings where applicable.

Frequently Asked Questions

What is the difference between threaded and welded end caps?

Threaded end caps allow for disassembly and maintenance, while welded caps provide permanent, leak-proof seals for high-pressure applications.

How do I select the right material for corrosive environments?

Stainless steel 316 offers superior corrosion resistance for chemical applications, while PTFE plugs are ideal for highly aggressive media.
