PTFE Envelope Gaskets – Versatile and Reliable Sealing Solutions
At S.P. Engineers, we manufacture and supply high-quality PTFE Envelope Gaskets, designed for applications requiring excellent chemical resistance and durability. These gaskets combine the unique properties of PTFE with the mechanical strength of insert materials, making them ideal for aggressive chemical environments and varying temperature conditions.
With precision engineering and customisation options, our PTFE envelope gaskets cater to a wide range of industries, including chemical processing, pharmaceuticals, food, and petrochemicals.
Why Choose PTFE Envelope Gaskets from S.P. Engineers?
PTFE envelope gaskets are known for their versatility, durability, and ability to handle extreme conditions. They are designed to provide reliable sealing while resisting aggressive chemicals, high temperatures, and pressure variations.
We offer a variety of designs and material combinations to meet your specific sealing requirements.
What Are PTFE Envelope Gaskets?
This combination ensures exceptional sealing performance, even in challenging applications.
PTFE envelope gaskets consist of,
- PTFE Outer Layer: Chemically inert and non-stick, offering superior chemical resistance.
- Insert Material: Provides strength and resilience, available in materials such as rubber, CAF, or metal.
Types of PTFE Envelope Gaskets
- A continuous PTFE envelope wrapped around the insert material.
- Suitable for applications with moderate chemical exposure.
- PTFE is precisely milled to encase the insert material for enhanced durability.
- Ideal for high-pressure and high-temperature applications.
- Features a welded PTFE layer for seamless protection.
- Suitable for applications with extreme chemical exposure.
