Heat Shrink Tubing 3/8 Inch Black Electrical Wire Protection – 6 Pack

Description

When you’re fixing a wire harness in the field or protecting a fresh electrical connection, you need something that’ll hold up to the elements and keep working season after season. This 3/8-inch heat shrink tubing gives you a professional seal that keeps moisture, dirt, and corrosion away from your connections—because the last thing you need is an electrical gremlin showing up during planting or harvest.

What You’re Getting

• Military-grade polyolefin construction that won’t crack, split, or melt under pressure
• 2-to-1 shrink ratio means it fits snugly over irregular shapes and wire bundles
• Temperature rated from -67F to 275F for continuous use—handles everything from winter repairs to hot engine compartments
• UL listed and meets military specs for reliability you can count on
• Flame retardant material adds an extra layer of safety around electrical work

Built for Real Farm Work

Whether you’re splicing wires on a combine header, fixing lights on your spray rig, or bundling harnesses on any piece of equipment, this tubing handles the vibration and weather that farm machinery dishes out. The 4-inch length gives you plenty of coverage for most repairs, and you get six pieces in the pack to tackle multiple jobs.

Made to Last

This isn’t your basic hardware store heat shrink—it’s the same grade used in military and industrial applications. The irradiated polyolefin construction stays flexible in cold weather and won’t get brittle from UV exposure. Once it’s shrunk down, it forms a tight seal that keeps doing its job through years of field work.

Good to Know

Shrinks at 250F, so a standard heat gun does the job perfectly. Work from the center outward to avoid air bubbles, and don’t overheat—just enough to get it snug. If you’re doing the repair away from power, a lighter works in a pinch, but keep it moving to avoid hot spots.
