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

ที่ เฮงโกซีล, 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?

หนึ่ง โอริง 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 ไกด์ซีลไฮดรอลิก.

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:

How Do You Measure O-Ring Sizes Correctly?

For the perfect fit, always measure:

• ID (เส้นผ่านศูนย์กลางภายใน)
• OD (เส้นผ่านศูนย์กลางภายนอก)
• CS (ความหนาของหน้าตัด)

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 โอริง FKM:

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

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

Pricing depends on:

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

We explain pricing strategies in our คู่มือการเลือกและราคาโอริง.
