Product Description
Waterproof Nut Sealing Material Consultant | Multi-Material Selection (Silicone/FKM) & Compression Ratio Design
1.Waterproof nuts Quick Detail
The core performance of waterproof nuts lies in the material science and precision mechanical design of the sealing ring. We not only offer standard EPDM solutions, but also possess a material library covering silicone (resistant to high and low temperatures), fluororubber (resistant to oil and chemicals), and nitrile rubber (resistant to petroleum-based oils). By precisely calculating the compression ratio (typically 20-30%) and designing a matching sealing groove, we ensure that the sealing ring generates a stable and durable sealing force after installation, rather than simply "tightening." This solves the industry problem of premature failure of seals due to stress relaxation, aging, or media corrosion.
2.Waterproof nuts tProduct Description
Truly reliable sealing requires understanding the mechanical behavior of the seal in a confined space. We analyze compressive stress distribution, contact pressure, and modulus changes at different temperatures. For example, for automotive engine bay applications, we recommend Fluorocarbon Rubber (FKM) for its excellent elasticity and sealing performance in 150°C high temperatures and engine oil environments. For outdoor equipment with frequent thermal cycling, Silicone with low compression set is a better choice. We act as your “Sealing Consultant,” helping you avoid material selection pitfalls and make decisions based on scientific data.

|
Feature |
Advantage to You |
|
Application-Based Material Science Selection |
We offer a clear material comparison matrix (temperature range, media type, hardness options) to help you select the best sealing material based on the actual liquid, temperature, and pressure you will be in contact with, thus avoiding seal failures and after-sales issues caused by incorrect selection. |
|
Precision Groove Design & Controlled Compression Ratio |
Our nut seal grooves are optimized via FEA to ensure the seal material flows uniformly under compression, forming an optimal sealing interface. The standard 20-30% compression ratio ensures sufficient sealing force while preventing excessive compression that leads to premature aging or tearing of the rubber. |
|
Focus on Long-Term Performance: Compression Set |
We select high-quality rubber compounds with low compression set (such as EPDM ≤ 20% @ 70h/100°C). This means that the sealing ring can maintain good resilience after long-term pressure, ensuring that the sealing performance of the product does not degrade after several years of use, meeting the requirements of long service life design. |
|
Quantifiable Sealing Performance Testing |
In addition to standard IP testing, we can perform more sophisticated helium mass spectrometry leak detection or pressure decay testing, providing specific leakage rate values. This provides crucial quantitative input and verification basis for your high-reliability designs, such as battery pack sealing. |
|
Co-Development for Special Media |
If your application involves special chemicals, fuels, or extreme temperatures, our materials engineers can collaborate with you to develop or match the most suitable sealing solution through sample testing and compound adjustment. |

5.Waterproof nuts tProduct Application
New Energy Vehicle Powertrain Systems: Battery pack high and low voltage interface cover sealing (FKM/silicone recommended), motor controller housing (EPDM/silicone recommended) to prevent water and dust ingress leading to short circuits or insulation failure.
Outdoor High and Low Temperature Cycling Equipment: Communication base station equipment and solar tracker electrical boxes used in cold or desert regions require sealing materials that do not crack and maintain elasticity under repeated cycling from -40°C to +85°C (silicone recommended).
Industrial Cleaning and Corrosive Environments: Food processing equipment and chemical sensor housings require sealing rings that can withstand high-pressure water washing, steam, or specific chemical sprays (EPDM or FKM should be selected based on the specific medium).
Long-Term Buried or Underwater Equipment: Pipeline monitoring instruments and underwater connector housings require sealing materials with extremely low water absorption and long-term compression relaxation rates to ensure decades of sealing reliability (special formulation development required).
