Fisher 1000-5001 Genuine OEM Washer Bonnet

In pumps, a bonnet is a metal covering for the openings in the valve chambers. A bonnet may be any of various hoods, covers, or protective devices. The bonnet is connected with the body by a threaded, bolted, or welded joint connection and different types of gaskets are used to ensure leak-free connections between the body and the bonnet.

A washer is a thin plate (typically disk-shaped, but sometimes square) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Other uses are as a spacer, spring (Belleville washer, wave washer), wear pad, preload indicating device, locking device and to reduce vibration (rubber washer). Spring washers, which have axial flexibility are used to prevent fastening or loosening due to vibrations. Locking (lock) washers prevent fastening or loosening by preventing unscrewing rotation of the fastening device.
