Suction cup is a device, usually made of rubber or plastic that sticks to smooth, nonporous surfaces. They are usually used to attach objects together with the use of suction. Upon pressing the suction cup to a surface, the air pressure inside is drastically reduced. The relatively higher atmospheric pressure forces the cups to stick to the surface. They can be used as safety device by climbers of sky-scrapers.
Suction diffusers provide maximum flow efficiency at the suction side of the pump while reducing space and fitting requirements. It features blow down connection, adjustable support foot and tapped suction gauge port. It is used in commercial HVAC and industrial applications.
Suction Grease Guns hold up to 18 ounces of fluid flexible nozzle for transmission, diffential or oil filter service. The precision follower fitted to barrel for superior suction and is impervious to oil, grease and water. It is finished in rust - resistant, powder coated blue paint. This is suitable for draining of non-corrosive lubricants.
