Unlike standard O-rings, the triangle (X-profile) geometry combined with AED-resistant FKM compound significantly reduces internal gas trapping, minimizing blistering, cracking, and seal failure during rapid pressure drops.
Designed specifically for rapid gas decompression environmentsBetter sealing reliability than conventional O-rings
Reduced risk of blistering, cracks, and premature failure
Suitable for harsh media and extreme pressure cycles
This seal is widely used in oil & gas, chemical processing, hydrogen systems, and high-pressure valves, where reliability under extreme pressure fluctuations is critical.

Frequently Asked Questions
What is the difference between a Triangle Ring and a standard O-ring?
+
-
The triangle profile reduces gas trapping and provides multiple sealing points, significantly improving resistance to explosive decompression.
Is this product compliant with AED standards?
+
-
Yes, AED-grade FKM compounds can meet NORSOK M-710 and other industry requirements upon request.
Can it replace standard FKM O-rings directly?
+
-
In most static and low-speed dynamic applications, yes. Groove design confirmation is recommended for optimal performance.
Can custom sizes and hardness be supplied?
+
-
Yes. Custom dimensions, hardness, and compound formulations are available.
What is the expected service life compared to standard FKM O-rings?
+
-
In AED environments, service life is significantly longer due to reduced internal damage and better pressure recovery behavior.
