3M EPS300 Adhesive Lined Heat Shrink Tube 48" Black 5 PCS
Adhesive-lined polyolefin tubing shrinks 3:1 to seal 4/0 AWG to 500 MCM wire, resisting abrasion, chemicals and temperatures from -67 °F to 230 °F
- 3:1 shrink ratio seals large 4/0–500 MCM cables
- Adhesive lining creates moisture-proof, abrasion-resistant seal
- Polyolefin wall resists acids, alkalis and flame
- Operates from -67 °F to 230 °F
- 48-inch sticks shrink to 0.32 in ID with 0.1 in wall
3:1 Shrink Ratio Tubing
This adhesive lined polyolefin tubing shrinks three to one, sealing wire splices up to 500 MCM. Each black piece measures forty eight inches long before heating. The thin wall design keeps bulk low while the inner adhesive melts to block moisture and contaminants. It is suited for electricians and automotive technicians who need reliable environmental seals.
Upgrade from standard heat shrink
Standard tubing without adhesive leaves gaps that let water and chemicals reach the conductor. This product adds a factory applied adhesive layer that flows at two hundred fifty degrees Fahrenheit and bonds to insulation and connector bodies. The jump is worth it when the installation sees vibration, salt spray or burial conditions where plain shrink would fail.
Verify wire size and heat source
Confirm the conductor falls between 4/0 AWG and 500 MCM so the recovered inside diameter of zero point three two inches grips correctly. Ensure your heat gun or torch can reach at least two hundred fifty degrees Fahrenheit without exceeding two hundred thirty degrees Fahrenheit on sensitive components nearby. The tubing is rated from minus sixty seven to two hundred thirty degrees Fahrenheit once installed.

Questions about this item
What is the inner diameter before shrinking and the shrink ratio of this 3M EPS300 tube?
The tube has a 1 in inner diameter before shrinking and a 3:1 shrink ratio, reducing to 0.32 in after full recovery.
What is the minimum shrink temperature and what tool is typically used to reach it?
The minimum shrink temperature is 250 Degrees F; a heat gun is normally used to apply even heat until the adhesive flows and the wall reaches 0.1 in thickness.
What temperature range and environmental resistances does the installed tubing withstand?
After installation the tubing operates from -67 Degrees to 230 Degrees F and resists abrasion, acids and alkalis.
