ABSTRACT:
A wear insert for a plate adapter of a swivel bowl apparatus which is a vital part of a debris intake hose system. Such system utilizes a high vacuum by means of a high pressure blower. Under a high vacuum, sand and other abrasive properties cause severe wear to the plate adapter wall due to the rocking action of the swivel bowl. Such wear eventually render the system inoperable. The wear insert restores immediate operability of the system without repair or replacement to the plate adapter.
