Silicone Seals and Gaskets Manufacturer | Custom OEM Silicone Sealing Solutions for Industrial & Food-Grade Applications
Introduction
If you're sourcing silicone seals and gaskets that actually perform under real working conditions-not just on paper-you're in the right place.
At Xiamen Jinshun Sealing Technology Co., Ltd., we manufacture custom silicone sealing components designed for durability, compliance, and precision. With over 22 years of hands-on experience, we support global OEMs with reliable sealing solutions for industries like water systems, food equipment, electronics, and automotive.
Whether you need high-temperature resistance, food-grade safety, or tight tolerance control, we build silicone seals that hold up where it matters most.
Why Silicone Seals and Gaskets Are the Preferred Choice
Silicone rubber has become the go-to material for modern sealing applications-and for good reason.
Here's what makes silicone gaskets and seals stand out:
- Wide temperature range: Performs from -60°C to +220°C without cracking or deforming
- Excellent flexibility: Maintains sealing even on uneven or dynamic surfaces
- Chemical stability: Resistant to water, ozone, UV, and many chemicals
- Safe for sensitive applications: Ideal for food-grade and drinking water systems
- Long service life: Lower replacement frequency = reduced maintenance cost
For OEM buyers, this translates into fewer failures, better compliance, and stronger product reliability.
Key Features of Our Silicone Seals and Gaskets
✔ Fully Customizable (OEM / ODM)
We don't sell off-the-shelf limitations. We manufacture based on your exact needs:
Custom shapes (flat, square, complex profiles)
Custom sizes (micron-level precision)
Pantone color matching
Logo branding and packaging
✔ Precision Manufacturing (±0.05 mm Tolerance)
Tight tolerances are critical for sealing performance. Our advanced molding systems ensure:
Consistent dimensions across batches
Stable sealing performance under pressure
Reduced leakage risk in critical systems
✔ Adjustable Hardness Range (Shore A 15–90)
Different applications require different sealing behavior:
- 15–30 Shore A → ultra-soft for delicate sealing
- 40–70 Shore A → general industrial use
- 70–90 Shore A → high-pressure environments
✔ Certified for Global Markets
We use high-quality raw materials compliant with:
- FDA / LFGB → food contact safety
- NSF / WRAS / ACS / KTW-W270 → drinking water systems
- ROHS / REACH / PAHS → environmental compliance
This ensures your products meet EU, US, and international regulations.
