Chemical-Resistant Flexible Connectors for Industrial Chemical Processing

Chemical processing environments present a unique and complex set of challenges for flexible connectors. Chemical exposure, elevated temperatures, pressure and vacuum conditions, and stringent safety requirements all need to be factored into every connector choice. Using the wrong material — or a connector that doesn't seal correctly — can result in chemical exposure to workers, product loss, or worse.


Siftex designs and manufactures flexible connectors for chemical processing operations with a deep understanding of what's at stake. We work with chemical manufacturers to select materials that are chemically compatible with your specific media, rated for your temperature and pressure conditions, and engineered to maintain a secure, leak-free connection throughout their service life. With over 35 years serving chemical processors across a wide range of applications, we know how to get it right.

The Right Material Makes All the Difference

In chemical processing, material compatibility is everything. A connector that performs flawlessly with one chemical compound can degrade, swell, or fail entirely when exposed to another. That's why Siftex doesn't just sell connectors — we consult on them.


Our product experts will review your chemical media, concentration, temperature, and operating conditions before making any recommendation. We cross-reference material compatibility data to ensure that every connector we specify is suited for long-term performance in your specific chemical environment.

Siftex delivers for chemical processing operations:

Wide range of chemically resistant connector materials — including PTFE (SlipFlex), polyurethane, rubber compounds, and specialty fabrics

Pressure and vacuum-capable connector designs for demanding process conditions

Dust and vapor-tight seals to protect workers and meet safety and OSHA requirements

Custom connectors for reactors, dryers, screeners, pneumatic conveying systems, and transfer points

Material compatibility review as part of every consultation

Frequently Asked Questions

  • How do I know which connector material is compatible with my chemical process?

    This is one of the most important questions in chemical connector selection, and it's exactly what our consultation process is designed to address. We'll ask you about the chemical(s) your connector will be exposed to, the concentration, temperature, and whether there are pressure or vacuum conditions — and then we'll confirm material compatibility before recommending a solution.

  • Does Siftex offer PTFE connectors for aggressive chemical environments?

    Yes. Our SlipFlex PTFE connectors are designed for applications where chemical resistance is the primary requirement. PTFE is one of the most chemically inert materials available and is suitable for a wide range of aggressive chemical environments. We offer both PTFE tubing and custom PTFE connectors.

  • Can Siftex connectors be used in applications with both chemical exposure and elevated temperatures?

    Yes, though material selection becomes more complex when both chemical resistance and high temperature performance are required. We have compounds and materials that address both — and our team will confirm the right choice for your specific operating conditions.

  • Do your chemical connectors meet any industry safety standards?

    Our connectors are manufactured with safety and compliance in mind. Depending on your application, we can provide material data and documentation relevant to your safety and compliance needs. Discuss your specific requirements during the consultation process.

  • How do Siftex connectors help prevent chemical dust or vapor release in processing plants?

    Our dust-tight connector designs create a consistent, secure seal at transfer points — preventing the escape of chemical dust, powders, or vapors into the work environment. This is particularly important in chemical plants where worker exposure limits (OELs) and air quality standards must be maintained. BFM-style snap-in connectors are a popular choice for chemical processing because they provide a proven, high-integrity seal with easy changeout.
