- Adhesive-lined polyolefin seals and protects connections
- 3:1 shrink ratio fits 16 to 12 AWG wires
- Flame-retardant material withstands -67 °F to 230 °F
- Abrasion- and chemical-resistant for harsh environments
- Twelve 48-inch pieces ready for multiple jobs
12-piece adhesive-lined heat-shrink kit
This pack contains twelve individual pieces of 3M EPS300 tubing, each 48 inches long with a 0.25 inch inside diameter before shrinking. The 3:1 ratio reduces the bore to 0.08 inch after heating, sealing 16 to 12 AWG wires with a 0.02 inch recovered wall. Black polyolefin construction provides abrasion and chemical resistance for automotive and electrical repairs.
Sustained environmental protection
The adhesive lining melts at 250 degrees F and bonds to the conductor insulation, creating a moisture barrier that remains intact across a continuous operating range of -67 to 230 degrees F. Flame-retardant polyolefin resists degradation during long-term exposure to engine-bay heat, vibration and fluid splash without the cracking seen in non-adhesive thin-wall sleeves.
Straightforward installation with common heat tools
A standard heat gun or butane torch applies the 250-degree-F minimum shrink temperature evenly along the 4-foot length; the thin wall recovers quickly so rework is simple if positioning shifts. The main failure mode is insufficient heat, which leaves the adhesive unactivated and the seal incomplete, so verify full recovery before returning the harness to service.

Questions about this item
How much heat does the 3M EPS300 tubing need to shrink properly?
The minimum shrink temperature is 250 degrees F, so a standard heat gun on low or medium setting will activate the adhesive liner and shrink the tube to its final size.
What wire gauges can I use with the 0.25 inch inside diameter before shrinking?
The tubing is rated for 16 AWG to 12 AWG wires, covering common automotive and household electrical repair sizes.
Will the shrunken 0.08 inch diameter still fit over older connectors I already have?
After shrinking, the 0.08 inch inside diameter and 0.02 inch wall create a tight seal; measure your connector bodies to confirm they pass through before heating.
