Tri-Clamp PTFE Envelope Gasket (PTFE with Viton Core)

Envelope Gasket – PTFE with Viton Core for Chemical and Pharmaceutical Applications
The Envelope Gasket – PTFE with Viton Core is engineered for demanding chemical, pharmaceutical, and high-purity applications. Its dual-layer design combines a chemically resistant PTFE outer shell with a flexible Viton inner core, delivering a secure, leak-free seal. Able to handle extreme temperatures from cryogenic lows to +400 °F, this gasket ensures system integrity under challenging conditions. Ideal for aggressive chemical environments, vacuum systems, and critical sanitary applications, it provides reliable performance, long-term durability, and regulatory compliance, making it a trusted solution for industries where standard gaskets fail.

KEY FEATURES

1. Dual-Layer Construction
PTFE outer shell resists acids, bases, and solvents, while the Viton core provides elasticity and adapts to clamp pressures, ensuring a secure, dependable seal.

2. Wide Temperature Range
Operates effectively from cryogenic lows up to +400 °F, maintaining sealing integrity even under extreme thermal conditions.

3. High-Purity Certified
Meets FDA standards, 3‑A sanitary regulations, and USP Class VI certification, suitable for pharmaceutical, biotech, and high-purity food and beverage systems.

4. Reliable Sealing Under Challenging Conditions
Viton core conforms under vacuum or uneven clamp pressure, minimizing leaks and supporting consistent, safe operation.

5. Chemical Resistance
PTFE shell protects against aggressive chemicals and solvents, providing long-lasting durability in demanding industrial or laboratory environments.
