Introduction
KAFLON’s H Series Spring Energized Seals are engineered for high-pressure, static, and intermittently dynamic applications. Designed with a helical spring and PTFE-based jacket, these seals offer superior sealing performance in environments where high temperature, chemical resistance, and low friction are critical.
These seals are ideal for use in hydraulic systems, chemical processing equipment, and other high-stress applications requiring extended service life, reduced friction, and reliable sealing performance under varying conditions.
🔧 Key Features of the H Series
Materials & Performance Options
H Series seals are available with a variety of material combinations to meet specific application needs, including:
Jacket Material:
PTFE (Virgin or Filled)
UHMW-PE
PEEK
FEP (Fluorinated ethylene propylene)
Spring Material:
Stainless Steel (Standard)
Elgiloy, Hastelloy (for high-corrosion or extreme-temperature environments)
These materials ensure the H Series seals perform in a wide range of chemical environments, temperatures, and pressures.
🏭 Range of Application
The H Series spring energized seals are designed for flange sealing in high-pressure applications, particularly where pressure gradient from inside to outside and intermittent motion occur.
Hydraulic & Fluid Power Systems
Seals for high-pressure cylinders, valves, and actuators
Chemical & Process Industries
Seals for pumps, reactors, and processing equipment handling aggressive chemicals
Energy & Oil & Gas Equipment
Seals for critical high-pressure and high-temperature systems
Mining & Heavy Equipment
Seals for rotary and dynamic equipment exposed to high load and abrasive environments
