FAQs
Is it waterproof?
Yes—when fully recovered, the adhesive-lined inner wall creates an environmental seal.
What heat source should I use?
A standard heat gun provides uniform heating and best results.
Will 2:1 fit larger splices?
2:1 shrinks to half its original diameter. Choose a supplied size 20–30% larger than your joint’s OD.
Is the tubing flame-retardant?
Yes—tested to VW-1 standard.
Can I cut it?
Yes—supplied flat; cut to length with a sharp knife or scissors.
