Frequently Asked Questions

What is the PS2F1 premium stainless steel liquid tight conduit?

The PS2F1 series is a premium reinforced flexible metal conduit combining stainless steel construction with a protective PVC outer jacket. It delivers exceptional corrosion resistance, IP66 water and dust protection, superior mechanical strength, and fire retardancy, making it the ultimate solution for harsh, wet, and chemically aggressive environments.

Why choose stainless steel with PVC jacket?

This combination provides maximum protection: stainless steel offers superior long-term corrosion resistance against chemicals and salt, while the PVC jacket adds water barrier, dust protection, EMI shielding, fire retardancy, and impact resistance. This dual-layer protection is unmatched for severe environments.

What IP rating does PS2F1 achieve?

The PS2F1 series achieves IP66 rating when used with S50 and S53 compatible fitting series. IP66 provides complete protection against dust ingress and powerful water jets from any direction, suitable for outdoor, marine, and water-exposed industrial locations.

What sizes are available?

PS2F1 series offers 8 sizes ranging from 1/4" (10mm) to 2" (53mm) nominal diameter. Available sizes include P095150S2F1, P125177S2F1, P161213S2F1, P208267S2F1, P260330S2F1, P350432S2F1, P400487S2F1, and P510594S2F1, with varying bending radii and packaging quantities.

What is the operating temperature range?

The PS2F1 series operates reliably between -20℃ and +90℃. This temperature range is suitable for most outdoor, indoor wet, and moderately heated environments. The limitation is due to PVC jacket constraints, so for extreme temperatures consider non-jacketed stainless steel alternatives.

What is the tensile resistance?

The PS2F1 series has tensile resistance greater than 1000N, providing exceptional mechanical strength and durability. This superior tensile strength ensures reliable performance under mechanical stress and vibration in harsh environments.

Why is stainless steel superior for corrosive environments?

Stainless steel provides exceptional resistance to pitting corrosion, stress corrosion cracking, and general corrosion in coastal, chemical, and salt-spray environments. Unlike galvanized steel which can degrade over time, stainless steel maintains protection indefinitely, making PS2F1 superior for long-term reliability.

Is the PVC jacket fire retardant?

Yes, the PVC jacket features self-extinguishing properties, meaning it will not continue burning when the ignition source is removed. This critical safety feature provides fire protection in hazardous locations and safety-critical applications.

What color options are available?

Black is the standard PVC jacket color, offering excellent UV resistance for outdoor applications. Other colors are available by special request for organizational identification or circuit management purposes. Contact our team to discuss custom color specifications.

Does the black PVC provide UV protection?

Yes, the black PVC jacket provides excellent UV resistance, protecting the internal stainless steel and preventing degradation from extended sunlight exposure. This makes PS2F1 ideal for outdoor installations requiring long-term durability.

What is the flexibility and bending radius?

PS2F1 features medium flexibility with bending radii ranging from 60mm (smallest 1/4" size) to 310mm (largest 2" size). While the PVC jacket adds thickness, it maintains good flexibility for routing in most industrial applications.

What applications is PS2F1 ideal for?

PS2F1 is specifically designed for offshore platforms, coastal facilities, chemical processing plants, petrochemical refineries, water treatment plants, food processing facilities, pharmaceutical manufacturing, and any location requiring superior corrosion and water protection combined with mechanical durability.

How does PS2F1 compare to PG2F1?

PS2F1 uses stainless steel (superior corrosion resistance) while PG2F1 uses galvanized steel. Both achieve IP66 and 1000N+ tensile strength with PVC jackets. Choose PS2F1 for chemical-aggressive or salt-spray environments, PG2F1 for general wet/harsh environments. PS2F1 offers better long-term value in severe corrosive conditions.

Is PS2F1 suitable for offshore marine applications?

Yes, PS2F1 is ideal for offshore platforms and marine environments. The stainless steel construction resists saltwater corrosion, the PVC jacket protects against spray and moisture, and the IP66 rating provides comprehensive protection. This combination makes it the preferred choice for marine cable management.

Is PS2F1 RoHS compliant?

Yes, the PS2F1 series is fully RoHS compliant, ensuring no hazardous substances are used in manufacturing and meeting international environmental regulations.

What certification does PS2F1 hold?

PS2F1 series holds CE certification, meeting European standards for cable protection in harsh industrial and marine applications with water and chemical exposure. The certification ensures compliance with relevant EU directives and safety standards.

What fitting series are compatible with PS2F1?

PS2F1 conduit mates with the S50 and S53 fitting series. These compatible fittings ensure a complete sealed system for achieving the IP66 rating and maximum protection against water and dust ingress in harsh environments.

What are the outer diameter specifications with the jacket?

The PVC jacket adds approximately 2.5-3.7mm to the outer diameter. For example, the 1/4" size has an OD of 15.0mm with jacket, the 1/2" size has 21.3mm OD, and the 2" size has 59.4mm OD. These specifications are important for space planning in tight installations.

What is the long-term cost benefit of PS2F1?

While PS2F1 has higher initial cost than galvanized alternatives, it offers superior long-term value: no corrosion-related maintenance or replacement, indefinite service life in aggressive environments, reduced downtime from failures, and lower total cost of ownership. For critical offshore and chemical applications, PS2F1 is the most economical choice.

What packaging quantities are available?

PS2F1 is available in rolls of 50 meters for smaller sizes (1/4" to 3/4"), and 25 or 15 meters for larger sizes (1" to 2"). Custom lengths can be cut to meet specific project requirements for marine and offshore installations.

Can custom specifications be ordered?

Yes, custom configurations are available for special requirements including custom colors, jacket materials, lengths, and fitting combinations for marine and offshore projects.
