ZO 1/2" Black Round End Cap Polyethylene Lamellae 21.3mm Tube Weather Resistant

Product Overview

Zaślepka okrągła calowa ZO 1/2" (fi 21,3) is a round polyethylene end cap designed for sealing pipe ends and profiles in mechanical, furniture, and construction applications. Manufactured via injection molding, the cap fits 1/2" (21.3 mm) round tubing and is typically used by fabricators, assembly lines, and maintenance operations requiring corrosion-resistant, dimensionally stable closure components for both indoor and outdoor use.

The featured lamellae on the lower portion of the cap differentiate this SKU, enabling adaptive fitting that accommodates varying wall thicknesses and ensures firm, durable attachment. This eliminates procurement risk associated with inconsistent tube tolerances and simplifies bulk installation processes. Particularly suited for OEM assembly projects and bulk procurement for furniture, rack, and framework fabrication.
