LSR LED Lighting Dustproof Waterproof Plug

# LSR LED Lighting Dustproof Waterproof Plug

---

Product Overview

The LSR LED Lighting Dustproof Waterproof Plug is a custom-molded liquid silicone rubber sealing component manufactured by 橡楚（湖北）橡胶有限公司 (Xiangchu (Hubei) Rubber Co., Ltd.), designed to provide reliable environmental protection for outdoor, commercial, and industrial LED lighting assemblies. Engineered from high-purity food-contact and industrial-grade liquid silicone rubber, this plug seals gaps between LED housing, wiring terminals, and mounting interfaces, blocking dust, moisture, rainwater, and airborne contaminants from entering sensitive lighting electronics.

Our LSR plugs are precision molded to match custom LED lighting design specifications, offering consistent compression performance and long-term weather resistance that outperforms conventional organic rubber seals. Unlike cut-and-stick foam or generic rubber plugs, our compression-molded LSR components maintain their sealing force through millions of thermal expansion/contraction cycles common in outdoor lighting applications, eliminating premature failure from cracking, compression set, or material degradation. As a specialist LSR manufacturer based at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, we produce these plugs to meet the dimensional and performance requirements of standard and custom LED lighting designs for global export markets.

Core selling points include: long-term UV and weather resistance, consistent waterproof sealing up to IP67 ratings, custom molding to exact design dimensions, and compliance with RoHS environmental standards.

Physical Performance

Finished plugs meet the following performance requirements for LED lighting applications:

Process Parameters

Our precision compression injection molding process delivers consistent finished parts with the following process controls:

• Dimensional tolerance: ±0.05 mm for features ≤10 mm, ±0.1 mm for features 10–50 mm
• Flash thickness: ≤0.02 mm (post-processed to remove excess material)
• Minimum wall thickness: 0.5 mm (standard wall thickness 1.0–3.0 mm)
• Cure conditions: 160–180°C for 3–5 minutes (addition-cured, no post-cure required for standard grades)
• Surface finish: 0.8–1.6 Ra μm (smooth, uniform sealing surface)

Product Advantages

1. Long-Term Outdoor Durability

Unlike EPDM or neoprene rubber seals that crack and harden after 2–3 years of UV exposure, our LSR material maintains 90% of its original elongation and hardness after 12 months of accelerated xenon arc weathering testing. This resistance to ozone, UV radiation, and temperature cycling ensures the plug retains its sealing performance for the full 50,000+ hour lifespan of most commercial LED lighting systems, reducing maintenance and replacement costs.

2. Precision Custom Molding for Exact Fit

We mold each plug to your exact CAD design dimensions, eliminating the gaps and poor sealing common with off-the-shelf generic plugs. Our precision LSR injection molding process produces consistent parts with tight dimensional tolerances, ensuring a snug interference fit in LED housing cutouts that maintains sealing force even as the housing expands and contracts with temperature changes.

3. Non-Toxic and Environmentally Compliant

All base LSR materials we use are free of heavy metals, phthalates, and other restricted substances, meeting global RoHS and REACH requirements for electronic products. For LED lighting installed in public spaces, residential buildings, or near food processing environments, our non-toxic LSR formulation eliminates leaching of harmful substances, supporting compliance with global import regulations.

4. Excellent Sealing Performance Across Temperature Ranges

LSR retains its elasticity and sealing force across a far wider temperature range than organic rubbers, making our plugs suitable for extreme climate applications from frozen northern outdoor installations to desert environments with high daytime temperatures. The low compression set of LSR ensures the plug does not permanently deform after long-term compression, maintaining consistent waterproof and dustproof protection over the product lifespan.

Applications

Our LSR LED Lighting Dustproof Waterproof Plugs are designed for a wide range of indoor and outdoor LED lighting applications, including:

1. Outdoor Architectural Lighting: Sealing wiring entry points and mounting gaps on street lamps, flood lights, landscape lighting, and facade lighting systems, preventing water ingress during heavy rain and snow.
2. Commercial LED Lighting: Sealing junction boxes and terminal connections on high-bay warehouse lighting, parking garage lights, and tunnel lighting, blocking dust and moisture from damaging LED drivers and circuit boards.
3. Marine and Coastal Lighting: Sealing LED navigation lights, dock lighting, and offshore platform lighting, where resistance to salt spray and high humidity is critical for long-term performance.
4. Residential Outdoor Lighting: Sealing gaps on garden path lights, wall sconces, and security flood lights, preventing insect and dust intrusion that can reduce light output and cause electrical failure.
5. Industrial Hazardous Location Lighting: Sealed LSR plugs for low-voltage LED lighting in industrial facilities with high dust or moisture levels, supporting reliable operation in wet process areas and manufacturing plants.

Selection Guide

Hardness Selection

Choose plug hardness based on your application's sealing requirements:

• 30–40 Shore A: Best for applications requiring high conformability to irregular housing surfaces, where maximum sealing contact is needed for low-pressure gap sealing.
• 40–60 Shore A: General-purpose hardness for most standard LED lighting applications, balancing conformability and mechanical rigidity for consistent long-term sealing.
• 60–70 Shore A: For high-vibration applications (such as roadway lighting near heavy traffic) or applications requiring higher mechanical resistance to impact, where rigid dimensional stability is a priority.

Size Specifications

We produce all plugs to custom dimensions based on your CAD design drawings. We do not maintain a fixed off-the-shelf size range, as each LED lighting assembly has unique housing dimensions and sealing requirements. We support prototype development for small-batch design testing, as well as mass production for full-scale manufacturing. Minimum order quantities for custom sizes are adjusted based on part complexity, and we provide free sample evaluation for qualified projects.

Material Grade

Select the appropriate LSR grade based on your application:

• Standard Industrial Grade: For general outdoor and indoor LED lighting applications, meeting all basic sealing and environmental requirements.
• Flame-Retardant Grade: UL 94 V-0 rated, for applications requiring high flammability resistance (such as commercial indoor lighting and low-voltage industrial lighting).
• Low-Extractable Grade: For LED lighting installed in food processing facilities, pharmaceutical production areas, or other sensitive environments requiring low volatile organic compound (VOC) emissions.
