Frequently Asked Questions
How do I pick the right heat shrink tubing size?
It depends on your wire or cable diameter—for example, 1/8 in. tubing suits thinner wires like 22 AWG, while larger sizes such as 3/8 in. and 1/2 in. fit thicker connections. Choose tubing that shrinks to about half its diameter for a tight, secure fit after heating.
What's the difference between single-size tubing and the assorted pack?
Single-size tubing like the HST-500 or HST-187 comes in one fixed diameter, ideal for repeating the same type of connection in bulk. The HST-AST assorted pack of 8 covers a range from 22 to 10 AWG, useful for smaller mixed jobs.
How do I properly apply heat shrink tubing?
Slide the tubing over the connection point first, then apply heat with a heat gun until it shrinks and grips the wire tightly. Make sure the tubing fully covers the splice before heating for a reliable seal.
Will plastic cable clamps fit any cable size?
Clamp sizes vary—3/8 in. clamps suit smaller cables while 1/2 in. clamps handle thicker ones. Check your actual cable diameter before buying to ensure a snug, secure mount.
When would I need a cable splice kit?
A Cable Splice Kit is useful whenever you need to join two or more wires securely and insulate the connection, whether for home or light industrial wiring. It provides the tools needed for a reliable splice without buying separate components.
