Inquiry (采购产品): Pneumatic tubes Hello My company is in need of replacement tubes for our pneumatic system. It is 30 years old and the tubes we use say "zip tube 2 1/4" They open from one end. It is an old leather snap button with a hard plastic cap. They are very worn and I would like to find some replacements. **** Hidden Message ***** Curt Cunningham 29515 318th Ave Se Ravensdale, WA 98051 USA Company: Louis Drefus Corp Title: Plant Operator E-mail: ibquiltin@unions-america.com **** Hidden Message ***** ibquiltin@unions-america.com
