SPR-PVC-AS
High-flex PVC-jacketed liquidtight conduit for general-purpose industrial protection
View ProductsLiquidtight Metal Conduits
Flexible jacketed metal conduits for industrial wire, cable, and fiber-optic bundle protection
Flexa liquidtight metal conduits are used where flexible metal protection must be combined with sealed outer-jacket performance in wet, oily, washdown, and contaminated industrial environments.
Available families include PVC, PU, silicone, and polyamide jacketed versions, along with braided, food-safe, and railway-approved liquidtight conduit options.
Flexa liquidtight metal conduits are available directly from IBIS, a key North American source for Flexa conduit solutions.

How to Choose the Right Liquidtight Metal Conduit
Liquidtight metal conduit selection depends on four main factors: jacket material, base conduit construction, added protection, and application-specific requirements.
Jacket Material
Use PVC for general-purpose liquidtight protection where high flexibility and standard industrial performance are the main priorities.
Use PU where tougher jacket performance, better abrasion resistance, lower-temperature capability, or more demanding industrial service conditions are involved.
Use silicone where chemical resistance and higher-temperature stability are important.
Use polyamide where high flexibility and higher-temperature all-purpose performance are required.
Base Conduit Construction
SPR families are the high-flex liquidtight option.
FLEXAgraff families are better suited where stronger wall construction, heavier-duty performance, or higher tensile strength are more important.
Braided Conduit Families
Braided liquidtight families are used where the application requires added outer mechanical protection, shielding, or protection against harsher installation conditions.
SPR-PVC-EDU-AS is the braided option for added outer protection and hot swarf protection.
FLEXAgraff-CU-PU is the braided option for EMC shield performance and heavy-duty protection.
Application-Specific Families
Some liquidtight families are selected for specific compliance requirements or operating environments.
Liquid-Tight-Food is for food and washdown-related applications.
PU-F families are for railway-approved applications.
SI-ASF is for chemical resistance and higher-temperature performance.
Applications for Liquidtight Metal Conduits
Liquidtight metal conduits are commonly used where wires, cables, and fiber-optic bundles require flexible metal protection with sealed outer-jacket performance.
Typical applications include:
- machinery and equipment wiring
- processing and packaging systems
- washdown environments
- food and beverage equipment
- railway and transportation applications
- installations exposed to oils, coolants, abrasion, or contamination
- applications requiring EMC / EMI shielding or added outer protection, depending on family
Frequently Asked Questions About Liquidtight Metal Conduits
What is the difference between liquidtight and non-liquidtight metal conduit?
Liquidtight metal conduit includes an outer jacket for sealed protection against moisture, oils, coolants, washdown, and contamination. Non-liquidtight metal conduit does not include that outer jacket.
When should I choose PVC-jacketed liquidtight conduit?
Choose PVC-jacketed liquidtight conduit for general-purpose liquidtight applications where high flexibility and standard industrial protection are the main requirements.
When should I choose PU-jacketed liquidtight conduit?
Choose PU-jacketed liquidtight conduit when tougher jacket performance, better abrasion resistance, lower-temperature capability, or more demanding industrial service conditions are required.
When is braided liquidtight conduit the better choice?
Braided liquidtight conduit is the better choice where added outer protection, shielding, or special mechanical protection is required.
Which liquidtight family is best for food, railway, or chemical-exposure applications?
Use Liquid-Tight-Food for food-related applications, PU-F families for railway requirements, and SI-ASF for chemical-resistant or higher-temperature applications.
