FKM TC Oil Seal
High-Temperature & Oil-Resistant Double Lip Shaft Sealing Solution
Product Overview
The FKM TC Oil Seal is a high-performance double-lip radial shaft seal designed for demanding applications involving heat, oil, pressure, and continuous rotation. It features a self-tightening spring fully encapsulated in rubber, ensuring stable sealing force and long service life even under harsh operating conditions.
Manufactured from FKM (Fluoroelastomer), this TC oil seal offers superior resistance to oils, fuels, chemicals, water, and high temperatures, making it a preferred choice for automotive, industrial, and heavy-duty machinery.
As a professional China custom FKM TC oil seal manufacturer, Xiamen Jinshun Sealing Technology Co., Ltd. provides both standard sizes and fully customized solutions for global OEM and aftermarket customers.
What Is a TC Oil Seal?
A TC oil seal is the most widely used oil seal structure in rotating equipment. It consists of:
- Primary sealing lip with a garter spring for oil retention
- Secondary dust lip for external contamination protection
- Rubber-covered metal frame for rigidity and easy installation
In most industrial contexts, when people refer to an "oil seal," they are usually referring to a TC framework oil seal.

Why Choose FKM Material for TC Oil Seals?
FKM (Fluorocarbon Rubber) is specifically selected for applications where standard rubber materials fail.
Key Benefits of FKM TC Oil Seals
- Continuous temperature resistance up to +200°C, short-term peaks up to +230°C
- Excellent resistance to engine oil, transmission oil, fuel, hydraulic oil, and lubricants
- Strong resistance to acids, alkalis, and chemicals
- Low compression set for long-term sealing stability
- Excellent wear resistance and aging resistance
Compared to NBR oil seals, FKM TC oil seals last significantly longer in high-temperature and aggressive media environments.

FAQs – FKM TC Oil Seal
Q1: What is the difference between TC and single-lip oil seals?
TC oil seals have an additional dust lip and a spring-loaded main lip, offering better sealing and contamination protection.
Q2: When should I choose FKM instead of NBR?
Choose FKM when operating temperatures exceed 120°C, or when the seal contacts aggressive oils, fuels, or chemicals.
Q3: Can you manufacture non-standard sizes?
Yes. We specialize in custom oil seals based on drawings or samples.
Q4: Are your FKM TC oil seals suitable for automotive use?
Yes. They are widely used in engines, gearboxes, and powertrain systems.
