STRESS SAVER® 3522

High‑Purity PTFE Sealing for Clean & Chemically Demanding Hydrogen Applications

Hydrogen technologies increasingly intersect with industries that require high purity, corrosion resistance, and fully hygienic sealing solutions. The STRESS SAVER® 3522, constructed from 100% pure, restructured PTFE, is specifically engineered to meet these needs, making it highly suitable for clean hydrogen processes, high‑purity gas systems, and applications where contamination control is essential.

In hydrogen production—particularly green hydrogen generated by electrolysis—gaskets frequently come into contact with ultra‑pure water, oxygen, and chemically aggressive environments. Materials must therefore provide both universal chemical resistance and absolute cleanliness. STRESS SAVER® 3522 excels in these environments due to its inert, homogeneous PTFE matrix that eliminates the risk of leachable contaminants or delamination.

Optimized for Multiple Flange Designs Used in Hydrogen Systems

The patented STRESS SAVER® sealing profile is designed to work effectively in:

High‑stress raised‑face metallic flanges commonly found in hydrogen processing equipment

Low‑stress non‑metallic flanges used in lightweight or corrosion‑resistant hydrogen systems

This versatility simplifies gasket selection and ensures reliable sealing performance across the diverse equipment types found in hydrogen production, storage, and distribution facilities.

The crush‑resistant PTFE structure provides stable sealing load distribution — an important factor for hydrogen systems where seal failure can impact both safety and process integrity.

Cleanability and Purity for Modern Hydrogen Requirements

Hydrogen applications frequently require strict cleanliness, especially in:

Electrolyzers

High‑purity hydrogen fueling systems

Pharmaceutical‑grade hydrogen production

Food‑compatible hydrogen processing environments

STRESS SAVER® 3522 is engineered to support these requirements:

The surface does not promote bacterial growth, supporting hygienic process conditions

Its pure PTFE composition ensures minimal extractables

The smooth, low‑energy surface is easy to clean and maintain

Key Advantages in Hydrogen Applications

Universally chemically compatible, covering all media encountered in hydrogen electrolysis and processing

High purity, ideal for clean hydrogen infrastructures

Reliable sealing across both high‑ and low‑stress flanges

Homogeneous construction, preventing permeation and delamination

Long-term durability, supporting stable, safe operating performance in hydrogen environments
