# Custom LSR Waterproof Protector Gasket
---
Custom LSR waterproof protector gaskets are precision-molded sealing components manufactured from high-purity liquid silicone rubber (LSR) by 橡楚（湖北）橡胶有限公司, located at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号. Designed to create reliable, long-lasting watertight and dust-proof barriers between mating components, these gaskets are custom-engineered to match the exact dimensional and performance requirements of your unique application.
Unlike generic cut gaskets or off-the-shelf seals, our custom molded LSR protector gaskets are formed through precision injection molding, enabling complex geometries, tight tolerances, and consistent performance across high-volume production runs. The inherent properties of liquid silicone rubber make these gaskets ideal for demanding environments where exposure to water, temperature extremes, UV radiation, and chemicals would degrade conventional rubber or plastic seals. Whether you need a small diameter gasket for a handheld electronic device or a large-form protector gasket for industrial enclosure, we can tailor material properties, dimensions, and surface finishes to meet your specification.

All our custom LSR waterproof protector gaskets are produced from virgin, low-volatility food-grade or industrial-grade liquid silicone rubber, with no recycled filler material. Key material properties include:
We offer a range of hardness grades to match application requirements, with consistent physical performance across all formulations:
Our precision liquid injection molding process delivers consistent, high-quality parts with the following process specifications:

As a specialized LSR manufacturer, our custom LSR waterproof protector gaskets deliver four key advantages over alternative sealing solutions:
Platinum-cured LSR maintains its elasticity and sealing force far longer than organic rubber or foam gaskets. It resists water swelling, hydrolysis, and degradation from long-term immersion or exposure to humid environments, eliminating the risk of seal failure that leads to water damage to sensitive internal components. Unlike glued or cut gaskets, injection-molded LSR gaskets have no joint gaps that can leak, providing a consistent watertight barrier across the entire sealing surface.
We offer full customization of geometry, hardness, color, and material grade to match your design. Whether you need integrated mounting holes, complex contour sealing surfaces, or specific compression characteristics, our engineering team can work from your 2D drawings or 3D CAD files to produce a gasket that fits your enclosure or component perfectly. No modification or trimming is required after delivery, reducing assembly time and error.
Our LSR protector gaskets resist UV radiation, ozone, aging, and common industrial chemicals including mild acids, alkalis, and cleaning agents. They do not crack, harden, or become brittle after years of outdoor exposure or temperature cycling, making them suitable for both indoor and outdoor use. The non-toxic formulation of our material also meets requirements for contact with food and skin for consumer and medical applications.
Liquid injection molding enables efficient, consistent mass production of custom gaskets with low per-unit cost after initial mold fabrication. We maintain strict process control to ensure every gasket meets dimensional and performance requirements, reducing rejection rates and supply chain delays for our customers.

To ensure you get the optimal custom LSR waterproof protector gasket for your application, follow this selection guidance when requesting a quote:
Provide full dimensional drawings or 3D CAD models (STEP or IGES format preferred) of your gasket, including critical tolerances for sealing surfaces, mounting hole positions, and overall dimensions. Our engineering team will review your design for manufacturability and suggest adjustments if needed to improve sealing performance and reduce production cost.
