Heyco® Universal Thermoplastic Rubber Grommets
In many electrical and mechanical applications, protecting cables, wires, and tubing where they pass through panels is critical. Sharp edges, vibration, and constant movement can quickly damage insulation and lead to costly failures. This is where Heyco® Universal Thermoplastic Rubber Grommets offer a reliable and practical solution.
Designed for flexibility and ease of installation, these grommets help protect and support cables while simplifying the installation process. Whether used in electrical enclosures, control panels, machinery, or equipment housings, they provide dependable cable management and long term protection.
A Flexible Design That Adapts to Your Application
Unlike traditional grommets that are designed for a specific cable diameter, Heyco Universal Thermoplastic Rubber Grommets use flexible internal shutters that adjust to the shape and size of the cable or bundle passing through the panel.
This design allows the grommet to support round cables, irregular shapes, or bundled wires without requiring multiple grommet sizes. Depending on the selected model, cables and bundles up to 2.4 inches (61.0 mm) in diameter can be accommodated.
The result is a versatile solution that helps simplify design and installation.
Features and Benefits
