Ideal 46-381 Adhesive Lined Heat Shrink End Cap
Adhesive-lined heat-shrink end cap seals 12–6 AWG wires, shrinking from .55 in to .18 in with a 3:1 ratio and .08 in wall
- Product typeCable Management & Conduit
- Seals 12–6 AWG wires with 3:1 adhesive-lined shrink
- Medium wall provides 0.08 in insulation after shrinking
- Cross-linked polyolefin resists UV exposure outdoors
- Withstands -55 °F to 110 °F operating range
- Shrinks fully at 248 °F minimum temperature
Medium-Wall Cable End Cap
This dual-wall end cap seals and protects wire terminations in general electrical and industrial work. It fits 12 AWG to 6 AWG conductors and shrinks 3:1 when heated. The cross-linked polyolefin body carries an adhesive liner that bonds to the cable jacket. Dielectric strength is rated at 1 000 V.
Suits sealed single-wire terminations
Builders who need a watertight seal on one cable will find the adhesive-lined wall effective. Installations requiring flame-retardant tubing should select a different product because this cap is not flame retardant. Projects that need multiple wires in one cap or a larger shrink ratio are not served by this part.
0.55 in to 0.18 in shrink range
The inside diameter contracts from 0.55 in before shrinking to 0.18 in after full recovery, a 3:1 ratio that determines whether your wire fits. Minimum shrink temperature is 248 Degrees F and the operating range spans -55 Degrees to 110 Degrees F. Length after shrinking is 1.75 in with a 0.08 in wall thickness.

Questions about this item
What wire sizes does the 46-381 end cap accept for a proper seal?
The 46-381 end cap is rated for use with wire sizes from 12 AWG to 6 AWG, covering a common range for automotive and industrial splicing.
Will the 46-381 end cap shrink onto my existing 0.55 in. diameter cable without splitting?
The 46-381 end cap has a pre-shrink inside diameter of 0.55 in. and a 3:1 shrink ratio, so it will grip cables up to that size down to a recovered 0.18 in.
How can I verify the 46-381 end cap has fully shrunk and the adhesive has flowed?
After heating to at least 248 Degrees F, the 46-381 end cap should reach a recovered inside diameter of 0.18 in. with a wall thickness of 0.08 in., and adhesive will be visible at the open end.
