What Our Customers Say

“The heat shrink tubing from Dicore is same as the tubing I used professionally before. It shrinks tight and seals with the hot glue inside of the tube. It also remains somewhat flexible after shrinking – a quality I look for because cheap tubing will cool hard and brittle, and will crack open if any sideways force is applied to it.”

David T • Electrician

“I have been sourcing Dicore’s heat shrink tubing for more than 4 years, they are always stable and reliable with very competitive prices, strongly recommended”
