The pinch hose is a crucial part of your blaster's operating system, and what stops the machine from blasting.
It is designed to be an inexpensive and easy to replace wear part. Where other systems have a complicated, costly, proprietary part that is difficult to replace, we have only an 18 inch section of blast hose. Shop for pinch hoses here.
The pinch hose should be rotated and visually inspected regularly, and should be replaced at the first signs of wear.
