Panduit CLT75PUV-0 Corrugated Loom Tubing, 0.75in UV-Resistant Slit Wall, 4265ft

Overview

The Panduit CLT75PUV-0 is a 0.75-inch slit-wall corrugated loom tubing supplied in a 4,265-foot (1,300-meter) package — a bulk-run quantity sized for large commercial wiring projects, security system cable runs, and outdoor infrastructure harness protection. Built from polypropylene with a UV-resistant formulation, this tubing handles direct sunlight exposure without becoming brittle or cracking over time, which is the main failure mode of standard, non-UV-rated loom on outdoor conduit racks and rooftop cable trays. The slit design runs the full length of the tube, so you can install it over a pre-built wire bundle or finished harness without pulling every conductor through from scratch. For integrators managing hundreds of feet of camera cable, access control wiring, or intercom runs, that single feature cuts installation time significantly compared to unslit conduit. CLT75PUV-0 (often searched as CLT75PUV 0) is the right spec when you need abrasion and crush protection on a run too long for individual conduit sections and too exposed for generic cable wrap.

Key Features

• Slit-Wall Design for Retrofit Installs: The full-length longitudinal slit means you can open the tube and snap it over an existing pre-wired harness or live bundle without disconnecting anything. On renovation projects or retrofit camera upgrades where pulling new conduit is impractical, this eliminates the need to re-terminate every end just to add mechanical protection.
• UV-Resistant Polypropylene Construction: Standard polypropylene yellows and embrittles under direct UV exposure within 12–24 months. The UV-resistant formulation in the CLT75PUV-0 is rated for outdoor deployment, so it maintains flexibility and impact resistance on rooftop cable runs, exterior wall drops, and exposed cable trays where sunlight is a constant factor.
• UL 94 HB Flammability Rating: UL 94 HB is a horizontal burn classification — meaning the material self-extinguishes or burns slowly in a horizontal orientation. For commercial and industrial installations where local codes require flame-retardant cable management, this rating supports compliance without requiring a more expensive halogen-free or V-rated material.
• 0.81-Inch Inside Diameter: The 0.81-inch (20.6 mm) ID accommodates bundled multi-conductor runs typical in security and low-voltage wiring — think a grouping of Cat6, coax, and 18/2 power in the same sleeve without the bundle binding. Measure your actual bundle OD before ordering; 0.81 inches is the usable bore, not the nominal 0.75-inch trade size.
• 185°F (85°C) Maximum Temperature Rating: Rated to 85°C continuous, this tubing handles conduit runs near HVAC equipment, mechanical rooms, and rooftop areas where ambient temperatures spike. Most generic loom is rated to 60–70°C; the extra thermal headroom prevents heat-induced softening in plant environments or hot attic runs.
• 4,265-Foot Bulk Quantity: At 4,265 feet (1,300 meters) per package, this is a project-quantity spool. It eliminates mid-run splices and reduces the number of separate orders on large-site deployments — a warehouse, campus perimeter, or multi-building security infrastructure installation where piecemeal 100-foot cuts would create unnecessary joins and material waste.
• RoHS Compliant: Meets Restriction of Hazardous Substances requirements, which matters for government facilities, healthcare environments, and any project spec that calls out RoHS compliance explicitly. No additional documentation request needed to confirm compliance status.
• Secure with Standard Cable Ties: The corrugated ribbing provides natural anchor points for cable ties and loom clips, keeping the tubing in position along a run without adhesive or special hardware. Any standard-width cable tie seats cleanly in the corrugation valleys.

Integration and Compatibility

The CLT75PUV-0 is compatible with any Panduit loom fittings, end caps, and strain relief connectors designed for the CLT corrugated loom series. It works alongside standard cable management hardware including Panduit cable ties, loom clips, and mounting brackets for routing along cable trays, ladder racks, or direct structural attachment. For outdoor security deployments, pair this tubing with UV-stable cable ties — standard nylon ties degrade outdoors faster than the tubing itself, negating the protection. In indoor industrial environments, review your wire routing and management plan for conduit fill percentages; the 0.81-inch ID sets the maximum bundle OD this tube will accept without restricting flexibility. This product is a abrasion protection solution and is not a substitute for liquid-tight conduit in wet or submerged locations — the slit design allows moisture ingress, so route it above waterline or transition to sealed conduit at any point with standing-water risk.

Frequently Asked Questions

Q: What is the inside diameter of the CLT75PUV-0?

A: The inside diameter is 0.81 inches (20.6 mm). The 0.75-inch designation is the nominal trade size; always check the actual 0.81-inch bore when sizing for a specific wire bundle.

Q: Is the CLT75PUV-0 rated for outdoor use?

A: Yes. The polypropylene is UV-resistant and rated to 185°F (85°C), making it suitable for outdoor cable runs exposed to direct sunlight. It is not liquid-tight, so it should not be used in submerged or continuous-moisture locations.

Q: How is the CLT75PUV-0 installed over an existing wire bundle?

A: The slit-wall design runs the full length of the tube. You open the slit, lay the bundle into the tube lengthwise, and close it around the cables. Secure it in place using cable ties seated in the corrugation valleys or with Panduit loom clips.

Q: What flammability rating does the CLT75PUV-0 carry?

A: UL 94 HB — a horizontal burn classification. This meets common commercial cable management flame-retardancy requirements without requiring a higher-rated (V-0/V-2) or halogen-free material.

Q: Is the CLT75PUV-0 RoHS compliant?

A: Yes. The CLT75PUV-0 meets RoHS (Restriction of Hazardous Substances) requirements as listed in the product specifications.

Q: How many feet are included in one package?

A: One package contains 4,265 feet (1,300 meters) of tubing. Package quantity is 1.

The CLT75PUV-0 is one of those spec-it-once, forget-it products — as long as you're sizing it correctly. The 0.81-inch actual ID is the number that matters on the job, not the 0.75-inch nominal, and I've seen bundles rejected mid-run because someone assumed the trade size was the usable bore. At 4,265 feet per package, you're committing to a project-scale buy, so get your bundle OD confirmed before the order ships.

Technical Highlights:

• UV-Resistant Polypropylene: Rated for continuous outdoor exposure — holds up on rooftop runs and exterior cable trays where non-UV-rated loom would chalk and crack within two seasons.
• 185°F (85°C) Thermal Rating: 15–25°C above most generic loom, which matters in mechanical rooms or attic cable paths where peak summer ambient temperatures push standard polypropylene to its limit.
• 4,265ft Bulk Format: Eliminates mid-run joins on large-site deployments. One package covers a full building perimeter or multi-zone security cable distribution without a splice point.

Deployment Considerations:

• The slit design is a productivity win on pre-wired harnesses, but it also means this tubing is not moisture-sealed. Transition to liquid-tight conduit or sealed fittings at any low point on an outdoor run where water could pool inside the slit.
• Pair with UV-rated cable ties, not standard nylon — on an outdoor run, nylon ties can degrade and release in 18–24 months, leaving the loom unsecured well before the tubing itself fails.

The CLT75PUV-0 is the right call on large outdoor security or industrial harness runs — perimeter camera cable trays, rooftop equipment drops, or exterior conduit bridges — where you need mechanical and UV protection at scale without piecing together short segments.
