Ever wondered how a small rubber ring can prevent a high-pressure hydraulic system from leaking? That’s the power of an 오링 — compact yet crucial, simple yet essential.

~에 헨고실, we’ve been manufacturing and exporting industrial-grade O-rings to over 20 countries. Whether your application involves hydraulic cylinders, pneumatic equipment, or automotive engines, choosing the right O-ring can make or break performance.

What Is an O-Ring and How Does It Work?

안 오링 is a circular elastomer seal that blocks the passage of fluids or gases between mechanical parts. When compressed in a groove between two surfaces, it deforms to create a tight seal that resists pressure, temperature changes, and vibration.

In hydraulic systems, this deformation is the key to leak-free operation. You can learn more about their role in fluid power systems in our 유압 씰 가이드.

How to Select the Right O-Ring Material for Your Application?

Material selection impacts temperature resistance, chemical compatibility, and lifespan. Here’s a quick reference:

재료	온도 범위 (°C)	주요 강점	일반적인 응용 프로그램
NBR(니트릴)	-40 ~ 120	우수한 내유성, 비용 효율성	연료 시스템, 유압 장치
FKM(비톤®)	-20 ~ 230	High temperature and chemical resistance	Aerospace, engines
EPDM	-50 ~ 150	Weather, ozone, and steam resistance	야외, HVAC
PTFE	-200 ~ 260	Chemically inert, food-grade	Medical, food, laboratory

If you’re unsure which to choose, see our detailed Silicone vs FKM O-Rings Comparison for complex environments.

How Do You Measure O-Ring Sizes Correctly?

For the perfect fit, always measure:

• ID(내경)
• OD(외경)
• CS(단면 두께)

Incorrect sizing leads to premature wear and leaks. Use our O-Ring Sizing Guide for step-by-step instructions.

Why Do O-Rings Fail and How Can You Prevent It?

Common causes of O-ring failure include:

• Wrong material choice for temperature or chemicals
• Over-compression or twisting during installation
• Exposure to incompatible fluids
• Reusing aged O-rings that lost elasticity

You can reduce downtime and replacement costs by following the preventive steps in our Seal Failure Prevention Guide.

Can O-Rings Handle Extreme Pressure and Temperature?

Yes, with the right compound.
For example, one manufacturer facing failures at 2500 PSI and 180°C switched to FKM O-링:

• Reduced leakage by 75%
• Extended service life by 5×
• Lowered maintenance costs by 40%

For multi-purpose stock, consider the O-링 모음 키트 to handle diverse applications.

How Much Do O-Rings Cost and What Affects Pricing?

Pricing depends on:

• Material type (NBR is economical, FKM/PTFE are premium)
• 크기 및 허용 오차
• Order quantity (bulk orders reduce cost per unit)

We explain pricing strategies in our O-링 비용 및 선택 가이드.
