Envelope gaskets are specialized sealing components designed to combine the chemical resistance of a fluoropolymer outer layer with the elasticity and sealing performance of an elastomer core. The outer envelope acts as a protective barrier between the process media and the gasket core, while the internal elastomer provides resilience and compression recovery. This design makes envelope gaskets ideal for applications requiring both strong chemical compatibility and reliable sealing, particularly in food, pharmaceutical, chemical, and hygienic processing systems.

Key Features

• Constructed with a fluoropolymer outer envelope surrounding a resilient elastomer core
• Combines excellent chemical resistance with reliable sealing and compression recovery
• Suitable for applications involving aggressive chemicals, solvents, or sensitive process media
• Smooth, non-stick outer surface helps reduce product buildup and facilitates cleaning
• Compatible with hygienic and industrial piping systems
• Available in multiple sizes and configurations to suit different sealing applications
• Designed for use in temperature and pressure ranges typical of food, pharmaceutical, and chemical processes
• Helps extend gasket service life by protecting the core material from direct media exposure
• Supports hygienic design requirements and contamination-control practices
