Petroleum Resistant Category Cables
Windy City Wire manufactures SmartWire® low-voltage petroleum resistant category cables designed for forecourt, c‑store, and other harsh environment applications where sunlight, gas, and oil exposure are common. Built for dependable data and control connectivity, these non-shielded 4‑pair cables are available in Category 5e (350 MHz) and Category 6 constructions, feature a black tint jacket, and carry a 300V rating. SmartWire is manufactured in the United States and supports projects that require consistent quality, clear specifications, and long-term reliability in demanding conditions.
For installers, SmartWire Glide lubrication is applied during manufacturing to reduce friction during pulls by up to 70%, helping cables move smoothly through conduit and tight pathways. Standard TIA/EIA pair color coding (Blue-White/Blue, Orange-White/Orange, Green-White/Green, Brown-White/Brown) supports straightforward termination in the field. With petroleum-resistant jackets and a compact nominal OD of 0.182 in, these cables help simplify installation while standing up to sunlight, gas, and oil exposure.
How Windy City Wire adds value
Choosing SmartWire petroleum resistant category cables means you get purpose-built, low-voltage wire from a single manufacturer who understands the unique demands of fuel facilities. Our product consistency, clear specifications, and job-matched constructions help reduce rework and downtime, so your team can deliver reliable connectivity across dispensers, forecourt controllers, canopy cameras, POS terminals, and back-office systems.

Petroleum Resistant Category Cables for Low-Voltage Networking in Fueling and Oil & Gas Environments
Windy City Wire’s petroleum resistant category cables are designed for the unique challenges of fuel, oil, and solvent exposure while delivering reliable Ethernet and low-voltage data performance for forecourt, terminal, and industrial sites. Built for harsh environments with a robust 300V construction and a black, sunlight-resistant jacket, these cables help networking equipment stay connected in areas where gasoline, diesel, oils, and petrochemical vapors are present.
Performance options for your network
Choose the level of performance your application demands, with options that include Category 5e (350 MHz) in 24 AWG and Category 6 in 23 AWG. Both options are unshielded twisted pair (UTP) to simplify grounding in metallic raceways and to maintain excellent signal integrity in typical petroleum-site layouts. A standard 4-pair color code (Blue/White-Blue, Orange/White-Orange, Green/White-Green, Brown/White-Brown) streamlines termination and testing. The nominal 0.182" OD supports straightforward conduit-fill planning in tight runs and existing infrastructure.
Where petroleum resistant category cable fits in your site
Use petroleum resistant category cables anywhere you need dependable IP or serial-to-Ethernet communications in proximity to fuels, oils, or cleaning solvents—indoors or outdoors. Common installations include:
How petroleum resistant category cable complements THHN, TFN, and TFFN
A complete petroleum-site installation often blends power/control wiring with network cabling. While petroleum resistant category cables carry data for IP devices and controllers, petroleum-resistant THHN, TFN, and TFFN rated wires are used for power and control circuits in the same environments:
In short: use THHN or TFN/TFFN for power and hardwired control circuits; use petroleum resistant category cable for Ethernet and low-voltage communications. This approach keeps systems code-compliant while ensuring each cable type is matched to its task and exposure.

Selection notes
Plan with confidence
Whether you’re networking dispensers on a forecourt, tying an ATG panel into the store network, or extending Ethernet to cameras across a tank farm, petroleum resistant category cables deliver the durability and performance required for oil and gas applications. If your project also includes power or control circuits, pair these data cables with petroleum-resistant THHN, TFN, or TFFN wiring in the appropriate raceways to complete a reliable, code-conscious installation. For help choosing between Cat5e 24 AWG and Cat6 23 AWG, or for conduit-fill and run-length planning, contact our team for assistance.
Available in two conductor sizes: 24 AWG (Category 5e, 350 MHz) and 23 AWG (Category 6). These are 4‑pair, unshielded twisted pair (UTP) low‑voltage cables.
Available conductor color options: Blue‑White/Blue and Orange‑White/Orange. The outer jacket is a black tint designed for harsh environments.
These petroleum‑resistant category cables are built with solid bare copper conductors to meet Cat5e/Cat6 performance for permanent installations.
Windy City Wire manufactures and stocks SmartWire petroleum‑resistant category cable in 1,000 ft as the standard length. It is also available in a 2,500 ft length for extended runs.
Our SmartWire petroleum cables are packaged in our patented RackPack carton to maximize labor savings and jobsite efficiency. Learn more about our RackPack: https://windycitywire.com/solutions/rackpack-overview
• THHN: Thermoplastic High Heat‑resistant Nylon‑coated building wire, typically PVC insulation with a nylon jacket, 600V, 90°C dry (often dual‑rated THHN/THWN‑2 for wet locations). Used for branch circuits and feeders in conduit.
• TFFN: Thermoplastic Flexible Fixture Nylon, a flexible (stranded) 600V fixture wire with PVC insulation and a nylon jacket, 90°C dry. Ideal for fixture leads, control cabinets, and equipment where flexibility is needed.
• TFN: Thermoplastic Fixture Nylon, the solid (non‑flexible) counterpart to TFFN, 600V, 90°C dry. Used inside fixtures, appliances, and control panels where solid conductors are appropriate.
All three can be specified in oil/gasoline‑resistant constructions; THHN is most common for general building wiring in conduit, while TFN/TFFN are intended for internal fixture and control wiring.
