Product Introduction
1. Material Selection
Each compound is chosen for its dominant strength, so you get the longest service life at the right cost:
- NBR (Nitrile) - Excellent resistance to oils, fuels and hydraulic fluids. First choice for automotive engine bays, fuel systems and hydraulic equipment.
- EPDM - Superior weather, ozone, UV and steam resistance. Ideal for outdoor equipment, HVAC systems, solar installations and hot-water appliances.
- CR (Chloroprene) - Balanced oil, flame, and weather resistance. Versatile option for general industrial sealing, electrical enclosures and construction hardware.
- Silicone - Extreme low- and high-temperature stability plus food-grade availability. Used in appliances, medical devices, lighting and food-processing equipment.
- NR (Natural Rubber) - Outstanding elasticity, tear strength and rebound. Suitable for dynamic sealing, vibration damping, and impact-absorbing mounts.
- SBR - Good abrasion resistance at a competitive price. Cost-effective solution for general-purpose grommets in low-load, indoor environments.
2. Typical Applications
- Wire and cable pass-through protection in metal or plastic panels
- Vibration isolation and noise reduction between components
- Sealing against dust, moisture, fluids, and contaminants
- Automotive wiring harnesses, fuse boxes, and battery compartments
- Electrical enclosures, junction boxes, and control cabinets
- Household appliances, power tools, and industrial machinery
