Panduit FT75-C Fiberglass Insulated Tubing

Panduit FT75-C is a 100-foot fiberglass insulated tubing designed for cable protection in high-temperature and harsh-environment applications. The silver fiberglass construction provides heat resistance up to continuous operating temperatures while maintaining flexibility for routing through conduit, cable trays, and tight spaces. At 30.48 meters per reel, this tubing delivers full-coverage protection for multi-conductor power feeds, low-voltage data bundles, and hybrid cable runs in commercial buildings, industrial facilities, and outdoor enclosures where thermal cycling, moisture, or mechanical abrasion would degrade standard sleeving.

Key Features

100-foot continuous length reduces splice points and installation time on long runs

Fiberglass material resists heat, moisture, and mechanical wear in harsh environments

Flexible construction routes through conduit bends and cable tray transitions without kinking

Silver color provides neutral appearance for exposed installations in finished spaces

Compatible with power, data, and hybrid cable assemblies across multiple trades

Fiberglass insulated tubing provides a critical barrier between cable jacketing and environmental hazards that shorten service life. The woven fiberglass construction in the FT75-C maintains structural integrity across wide temperature ranges - essential when routing cables near HVAC equipment, rooftop enclosures, or industrial machinery where ambient temperatures fluctuate seasonally or during load cycles. Unlike PVC or polyethylene sleeving that can become brittle in cold or soften in heat, fiberglass maintains consistent protection characteristics from sub-freezing to elevated temperatures. The material is naturally resistant to moisture absorption, preventing the wicking and corrosion issues common in humid or condensing environments like underground vaults, parking structures, or coastal installations. At 100 feet per reel, you eliminate mid-run splices that introduce weak points and labor overhead - particularly valuable in long vertical risers or horizontal runs across mezzanines where access for future maintenance is limited.

Use this tubing when protecting cable runs in parking structure conduits, outdoor pedestal feeds to gate operators or perimeter IP cameras, or industrial control wiring near heat-generating equipment and motor controllers. The 100-foot length matches the typical spacing between pull points in commercial installations, letting you complete floor-to-floor risers or cross-building trunk runs with a single continuous sleeve and no mid-run transitions. Fiberglass construction makes the FT75-C suitable for mixed-use environments where the same cable path encounters both indoor climate-controlled spaces and outdoor or semi-exposed zones - you don't need to transition between sleeving materials at building penetrations or weatherhead entries. For datacenter hot-aisle installations or AV equipment racks with high-wattage amplifiers, the heat resistance prevents cable jacket degradation that triggers nuisance failures during peak load periods. The neutral silver finish blends into finished commercial spaces while maintaining visibility for maintenance crews, avoiding the aesthetic compromise of bright orange or yellow warning sleeves in occupied areas.

Fiberglass insulated tubing meets the mechanical and thermal protection requirements in NEC Article 300 for cable installations in harsh or high-temperature locations. The FT75-C's 100-foot continuous length and neutral silver finish make it the practical choice when you need reliable long-term protection without the maintenance burden of segmented sleeving, excessive splice points, or the aesthetic compromise of high-visibility colors in client-facing environments.
