About Oil Seals
What Are Oil Seals
Oil seals, also known as radial shaft seals, are essential components used to retain lubricants and prevent the entry of contaminants such as dust, dirt, and moisture. They are commonly installed on rotating shafts to ensure proper sealing performance and extend equipment service life.
Materials & Performance
We offer oil seals in a variety of materials to meet different operating conditions:
NBR (Nitrile Rubber) – suitable for general-purpose oil resistance and cost-effective applications
FKM (Viton®) – excellent resistance to high temperatures and aggressive chemicals
EPDM – suitable for water, steam, and weather-resistant environments
Silicone – flexible performance under extreme temperature conditions
Material selection can be customized based on temperature, pressure, and media requirements.
Our Manufacturing Advantages
Stable production capacity for large-volume orders
Strict quality control to ensure consistent performance
Support for standard and non-standard specifications
Reliable supply for long-term cooperation
Fast response and quotation within 24 hours

Frequently Asked Questions
What are oil seals used for?
Oil seals are designed to retain lubricants and prevent contaminants such as dust, dirt, and moisture from entering mechanical systems. They are critical components in rotating shafts, gearboxes, and hydraulic equipment to ensure long-term performance and reduced wear.
What materials are commonly used for oil seals?
We supply oil seals in NBR (for general oil resistance), FKM/Viton® (for high temperature and chemical resistance), EPDM (for water and weather applications), and silicone (for extreme temperature flexibility). Material selection can be customized based on your working conditions.
How do I choose the right oil seal?
Selection depends on shaft size, working temperature, pressure, rotation speed, and medium (oil, grease, water, etc.). If you are unsure, our team can recommend suitable types based on your application details.
Can you provide custom oil seals?
Yes, we support custom production based on drawings or samples. We can adjust dimensions, materials, and structural design to meet specific requirements.
What information is needed for a quotation?
Please provide inner diameter (ID), outer diameter (OD), thickness, material, quantity, and application details for accurate pricing.
What is your typical lead time and MOQ?
MOQ is flexible depending on product type. Lead time varies based on quantity and specifications, with faster delivery for standard sizes.
