Abrasive materials

What is the most durable hose for conveying abrasive glass filled materials?

[rickbatey]

Seamless stainless steel resin piping with big sweeping glass elbows. The use the shortest amount of flex hosing possible. To me the right PVC hose made for the task has worked best. Also note some high end resin hoses have arrows on them. Place these hoses in the system where the resin flows in the direction of the arrow. That's due to the interior finish of the hose when being manufactured.
