Product Overview
Engineered specifically for rectangular communication junction boxes, electronic control cabinets, and outdoor housing frames, our custom silicone square enclosure sealing gaskets provide absolute perimeter protection. Unlike standard seals that suffer from uneven compression at right angles, our precision-molded square gaskets ensure uniform sealing pressure across all linear edges and 90-degree corners. They deliver a flawless, heavy-duty barrier against water, dust, industrial corrosion, mold, and bacterial growth.
Core Performance & Technical Advantages
- Uniform Corner Compression & Anti-Tearing: With a high tensile strength of ≥ 2MPa and an elongation rate of 50%–150%, these gaskets resist mechanical stress and tearing at critical 90-degree corner joints, eliminating the primary leakage risk of square enclosures.
- Certified UL94 V-0 Flame Retardancy: Formulated with self-extinguishing silicone material to isolate thermal risks, significantly increasing the safety profile of high-power outdoor electrical cabinets and telecom enclosures.
- IP68 Extreme Weather Sealing: Maintains total sealing integrity from -40°C to +80°C. It easily handles intense rain, localized water pooling on flat enclosure tops, and heavy humidity in underground or pipeline installations.
- Dielectric Protection & Interference-Free: Boasts a volume resistivity of ≥ 1 × 10¹⁴ Ω·cm and a breakdown voltage of 18–20kV/mm, preventing high-voltage tracking and protecting fiber optic signals from electromagnetic disruption.

Typical Application Scenarios
- Square/Rectangular Telecom Junction Boxes: Placed within the housing frames of outdoor fiber splice closures to shield delicate fusion joints and maintain required fiber bending radii (≥ 40mm).
- Outdoor Power Distribution & PCB Cabinets: Provides secure bonding, encapsulation, and gap sealing for high-power capacitors, inductors, and electrical component frames against environmental hazards.
- Harsh Environment Infrastructure: Ideal for wall-mounted, overhead, or buried square control boxes operating in coastal, tropical, or sub-zero industrial fields.
