Stretchable rubber vacuum hoses have a near-zero bend radius and rebound to normal shape after being crushed.
They are designed for extreme temperatures and are chemical and abrasion resistant. Standard cuff sizing fits most off-the-shelf wet/dry and industrial vacuums. The hoses can be fitted with permanent-plastic adapters to suit most car-wash applications. Relaxed length of about 6 ft stretches to nearly 15.
