Galvanized Duct End Cap

Galvanized duct end cap is a standard round duct closure fitting for HVAC and spiral duct ventilation systems. Made of anti-corrosion zinc-coated galvanized steel, this durable duct end cover ensures stable structural performance for long-term duct termination. Offered with optional rubber gasket design, it supports both high-airtight sealing and ordinary closure scenarios to fit different engineering standards. Featuring complete standard size coverage and tool-free easy installation, it is widely used for temporary construction closure and permanent end sealing of air supply, exhaust and air conditioning round ducts in all ventilation projects.

Product Description

The Galvanized Duct End Cap is designed to close off the end of round duct and spiral duct systems in HVAC ventilation applications. It provides a simple and effective sealing solution for unused duct outlets, temporary closures, or permanent end terminations.

Manufactured from galvanized steel, this end cap offers good corrosion resistance, reliable strength, and long service life. It is suitable for commercial, industrial, and residential ventilation systems. Gasket and non-gasket versions are available to meet different sealing and installation requirements.

This fitting is commonly used as a duct closure cap, duct end cover, or ventilation duct end plate in air distribution and exhaust systems.
