Which of the following is a common use of rubber bands made from inner tubes?

• A. Permanent hold insulation in place
• B. Fasten wiring
• C. Seal joints
• D. Temporary hold insulation in place

Answer: (D)

Temporary holding insulation in place is the practical use for rubber bands made from inner tubes. Their stretch lets you wrap around pipes or batt sections, keeping insulation in position long enough to trim and then secure it with tape or proper fasteners. They’re inexpensive, reusable, and easy to remove without damage, making them ideal for a temporary hold. They aren’t used for permanent fastening because they can lose tension, degrade with heat and age, or slip over time. They aren’t meant for fastening wiring or sealing joints, which require dedicated fasteners and sealants.
