Hollow Sucker Rod Centralizer 價格:

The Injection-Molded Centralizer is manufactured using a one-shot molding process, directly injection-molding the centralizer onto the rod body. It features a strong bond with the rod body, high axial locking force, and large flow area during operation. The centralizer remains stationary, preventing wear on the rod body.
