Cryogenic Metal Seal Ring
Product Overview
KAFLON® Cryogenic Metal Seal Rings are specially engineered for ultra-low temperature environments, where conventional elastomer seals become brittle and lose sealing capability.
Designed using high-performance stainless steel and nickel-based alloys, these metal seals maintain mechanical integrity, elasticity, and sealing performance even at extremely low temperatures down to -196°C (liquid nitrogen conditions).
Material Options
| Material | Key Benefits | Typical Use |
|---|---|---|
| Stainless Steel (SS304 / SS316L) | Good toughness at low temperature | LNG pipelines, valves |
| Inconel® / Nickel Alloys | Superior strength and corrosion resistance | Extreme cryogenic & high-pressure systems |
| Aluminum Alloy | Lightweight, good thermal conductivity | Specialized cryogenic equipment |
| Custom alloys | Tailored for specific media | Hydrogen / LNG applications |
FEATURE 01
Excellent performance at cryogenic temperatures (down to -196°C)
FEATURE 02
Resistant to thermal contraction and material embrittlement
FEATURE 03
Stable sealing under pressure fluctuations
FEATURE 04
No risk of cracking like elastomer seals
FEATURE 05
High reliability in gas and liquid cryogenic media
FEATURE 06
Long service life in extreme environments
Typical Applications
KAFLON® Cryogenic Metal Seal Rings are widely used in:
LNG storage and transport systems
Cryogenic valves and flanges
Liquid nitrogen and oxygen systems
Hydrogen energy equipment
Cryogenic pipelines and loading arms
These applications require absolute sealing reliability under extreme cold and pressure variations.
