Size, Wall Thickness, and Roll Length

Confirm physical dimensions to ensure the tubing fits your cable and joint configuration. The product is supplied as a 25 ft roll with heavy-wall thickness.

• Expanded diameter: 3.54"
• Recovered diameter: 1.18"
• Wall thickness: 0.16"
• Length: 25 ft (continuous roll)

Installation Overview

Slide the tubing over the joint or splice and apply heat evenly from the center outward until the tubing has fully recovered. Because this SKU has no adhesive liner, additional sealing methods should be used if an adhesive or moisture seal is required for your application.

• Non‑lined (no adhesive liner)
• Apply heat evenly from center outward until fully recovered
• Verify full recovery and even wall conformity over the splice

Applications and Environments

The Morris 68196 is intended for heavy-duty cable protection in terrestrial installations, including direct-buried and underground applications, per the product description.

• Listed for direct-burial and underground cable joints and terminations
• Sized for large conductors in the 800 MCM–1250 MCM range

Before You Order

Confirm the model number and cable size required before ordering; this SKU is a non‑lined heavy-wall tubing sized for 800–1250 MCM cable and supplied as a 25 ft roll.

• Verify conductor size (800 MCM–1250 MCM) and required recovered diameter (1.18")
• If an adhesive liner or integrated sealing is required, choose a lined product or additional sealing method — this SKU is non‑lined
• Confirm quantity required for your project
