4:1 Ratio Raise Efficiency: Shrink to 1/4 of its original diameter; quick and solid; used for the contraction protection of irregular shape objects Adhesive Lined and Dual Wall: Hot melt adhesive on the inner wall; seal the materials at the two ends of the connection after shrinking; achieve an insulate sealing effect Protective Material: Made from polyolefin; effectively flame retardant and easy to use; suggested to shrink by heating with the hot air gun Multiple Applications: Used in industrial maintenance, marine, and automotive; also used in wire connection, rust prevention of solder joints, audio, and electrical DIY Variety of Sizes: 5 useful selections of sizes to choose from including 1/4 inch, 1/2 inch, 5/8 inch, 3/4 inch, and 1 inch; not the outer diameter of the flat state but the BuyUneed heat shrinkable tube diameter of the round state About 4: 1 heat shrink tube 4: 1 double wall heat shrinkable flame retardant sleeve is a type of heat shrink tube.
The outer layer is made of soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive.
The outer material has the advantages of insulation and wear resistance, and the inner layer has the advantages of low melting point, waterproof, sealing and high adhesion.

How to use heat shrink tubing ？
STEP 1 : Cut to the right size tubes you need.
STEP 2 :Wrap the cable wire with the tube,then use a hair dryer or heat gun heating it until the wire was wrapped tightly.
TIPS : Don't touch the tube until it becomes cool.
How is it measured heat shrink tubing?
Shrink tube is measured using the inside diameter when held in a tube position. This is the diameter of wire, tube or other cylindrical material that it will cover. It is shipped flat and will naturally be wider in this orientation than its inside tube measurement.
