Panduit KP-HSTT2 Dry-Shrink Heat Shrink Tubing Kit

Overview

The Panduit KP-HSTT2 is a multi-color heat shrink tubing assortment kit packaged in a reusable plastic case, designed specifically for dry-location wire management and identification tasks. Built on Panduit's Dry-Shrink™ platform, the KP-HSTT2 (often searched as KP HSTT2) gives installers a ready-to-use selection of cross-linked polyolefin tubing in various sizes and colors — one kit covers most field termination and color-coding needs without hunting for individual part numbers. Each kit ships as a single package unit with 6 inches (0.5 ft / 0.15 m) of total tubing across the included sizes.

Key Features

• Cross-Linked Polyolefin Construction: Cross-linking raises the polymer's continuous service temperature ceiling and improves resistance to abrasion and fluid exposure versus standard polyolefin. In termination bays and patch panels, that durability means the sleeve stays intact through future rework rather than cracking under mechanical stress.
• Multi-Color, Multi-Size Assortment: Color-coded heat shrink is the lowest-cost way to enforce conductor identification standards — instead of stocking six separate SKUs, the KP-HSTT2 puts the full color range in one plastic case. Reducing SKU count in a van stock or field kit cuts reorder complexity and eliminates the frustration of having the right size but the wrong color on-site.
• Dry-Location Rated: The kit is rated and specified for dry locations. Do not deploy this in conduit runs exposed to standing water, outdoor wet environments, or wash-down areas — those applications require a gel-filled or adhesive-lined heat shrink rated for wet/outdoor exposure.
• UL Recognized / CSA Approved / MIL SPEC Standards: Meeting UL recognition, CSA approval, and MIL SPEC means the tubing is accepted by AHJs and passes inspection on commercial and government projects where listing documentation is required. If your job requires a specific listing on submittals, this kit covers the common North American compliance bases.
• Reusable Plastic Case: The plastic case organizes the assortment and survives daily tool-bag abuse better than a cardboard blister pack. For technicians running structured cabling or low-voltage security installs, a case that stays closed in a bag matters on multi-day jobs.
• Single Package Quantity: Sold as one kit per unit — pricing and ordering reflect the complete assortment, not individual tubes. Straightforward for project-based purchasing or stocking a service vehicle.

Integration & Compatibility

The KP-HSTT2 is compatible with standard heat-shrink tooling — heat guns set to appropriate temperatures for polyolefin. The multi-size selection accommodates a range of conductor gauges and connector barrels common in low-voltage security, access control, and structured cabling installations. Panduit lists competitor cross-references FIT-221-MS-2 and FP-301-COLOR-ASSORTMENT for direct comparison when evaluating substitution on existing specs.

Frequently Asked Questions

Q: Is the KP-HSTT2 rated for outdoor or wet locations?

A: No. The KP-HSTT2 is specified for dry locations only. For outdoor, wet, or underground runs, select a heat shrink product rated for wet/outdoor exposure — adhesive-lined or gel-filled variants are the typical choice.

Q: What standards does the KP-HSTT2 meet?

A: The KP-HSTT2 meets UL Recognized, CSA Approved, and MIL SPEC standards, making it acceptable on commercial and government project submittals requiring listed heat shrink.

Q: What material is used in the KP-HSTT2?

A: Cross-linked polyolefin. Cross-linking improves temperature resistance and durability compared to standard polyolefin tubing.

Q: How much tubing is included in the KP-HSTT2?

A: The kit includes a total of 6 inches (0.5 ft / 0.15 m) of tubing across the various sizes and colors in the assortment.

Q: What are the direct cross-reference part numbers for the KP-HSTT2?

A: Panduit lists FIT-221-MS-2 and FP-301-COLOR-ASSORTMENT as cross-reference competitor parts for the KP-HSTT2.

The KP-HSTT2 fills a specific gap in the field kit: a UL/CSA/MIL SPEC-rated, multi-color cross-linked polyolefin heat shrink assortment in a single reusable case. When I'm commissioning an access control or structured cabling install and need color-coded terminations on the spot, having FIT-221-MS-2 and FP-301-COLOR-ASSORTMENT cross-referenced directly on this SKU saves time on equivalent substitution calls.

Technical Highlights:

• Cross-Linked Polyolefin: Higher continuous service temperature and better abrasion resistance than standard polyolefin — relevant in congested termination panels where sleeves see repeated contact from adjacent conductors and rework.
• UL / CSA / MIL SPEC Listed: Covers the three listing bodies that show up most often on commercial and federal project submittals. One kit, one line item on the submittal — less paperwork than sourcing equivalent individual rolls.
• 6-Inch Assortment per Kit: At 0.5 ft (0.15 m) total across all included sizes, this is a field identification and termination kit, not a bulk spool replacement. Right-size your order based on termination count, not linear footage.

Deployment Considerations:

• Dry-location rating is a hard limit — do not use the KP-HSTT2 in conduit or junction boxes subject to moisture intrusion, outdoor exposure, or NEMA 4/4X environments. The listing does not cover those conditions.
• Package quantity is 1 kit per unit ordered. If you're stocking a service fleet or covering a large-scale termination project, calculate kit count against expected conductor ID points, not against linear footage needs.

The KP-HSTT2 is the right call for commercial low-voltage installs — security, access control, or structured cabling — where AHJ submittals require UL/CSA documentation and color-coded conductor identification is part of the as-built standard.
