Manufactured as a single, integrated piece from highly elastic silicone, this component is soft to the touch and offers excellent resilience. It is non-toxic, odorless, and remains stable over long periods in both high and low-temperature environments; it resists hardening, cracking, and yellowing, while providing strong protection against aging and UV exposure.
Leveraging the inherent elasticity of the silicone, the plug fits snugly against the inner wall of a conduit and the outer sheath of a cable, creating a secure seal. These silicone plugs can be customized in terms of dimensions, aperture size, and color to meet specific requirements.
The silicone plug acts as a protective buffer for the cable sheath, shielding it from the sharp edges of openings and preventing the cable's insulation layer from being cut. Additionally, it fills the gap between the conduit and the cable, providing effective protection against dust and water ingress.
1.With its excellent elasticity, silicone can accommodate minor dimensional variations, fitting snugly into gaps within conduits. It effectively blocks the entry of dust, moisture, insects, and exhaust gases, thereby reducing the risk of short circuits caused by dampness. These plugs offer reliable, consistent protection, with an ingress protection (IP) rating of IP66–IP68.
2.Customizable, multi-functional silicone cable plugs are resistant to extreme temperatures and acid/alkali corrosion. They provide excellent electrical insulation, resist aging and deformation, and maintain their sealing performance over long-term use. Options for eco-friendly and flame-retardant materials are available to meet electrical safety standards, making them suitable for a wide range of environments—including indoor, outdoor, and high-humidity settings.
3.Beyond basic sealing and protection, these silicone plugs can be customized with specialized properties such as flame retardancy, electrical conductivity, or anti-slip surfaces. Furthermore, color, hardness, and custom logos can all be tailored to specific requirements.
Silicone cable plugs are widely used in building infrastructure—including residential plumbing and electrical systems, low-voltage installations, and HVAC/ventilation systems. They are ideal for sealing non-standard openings, such as those for conduits passing through walls, cable entry points in low-voltage enclosures, or apertures for air-conditioning lines. These plugs can be custom-engineered with multiple or irregularly shaped openings; common configurations include T-shaped plugs, conical plugs, grommets (pass-through sleeves), and waterproof cable-sealing plugs.
To meet specific requirements—such as flame retardancy, weather resistance, or oil resistance—these silicone plugs can be customized based on the dimensions of the openings in equipment enclosures and the specific cable routing layout. They are well-suited for use in power distribution boxes, control cabinets, outdoor photovoltaic (PV) installations, and cable outlets for precision instruments.
