Model 980 and 981 Oil and Fuel Filter Housings

Kaydon Model 980 and 981 Oil and Fuel Filter Housings are durable and robust inline pressure or return line (1,200 psig maximum) filter assemblies used for oil and fuel filtration applications.  Both the 980 and 981 are suitable for use with hydraulic systems used in mobile equipment, small industrial hydraulic power units, small lube systems, and diesel fuel transfer where larger filtration assemblies are not practical. They can be substituted for spin-on type filters where extra protection and a more rugged design are desired. The Model 980 is rated for a maximum of 20 gpm and the Model 981 is rated for a maximum of 40 gpm, for oils and diesel fuel (check pressure drop curves to determine initial {clean} pressure drops for your flow and viscosity). The Model 980 uses the KMP 9600 series 4-inch length elements* and the Model 981 uses the 8-inch length elements*, with media selection of 1, 3, 6, 12 and 25 microns. The inlet/outlet connections are 1.5-inch NPTF, reducing flow restriction, plus the internal flow path provides low pressure drop (flow resistance). A color-coded visual differential pressure indicator is provided to signal element replacement. Bowl removal is made easier with a hand grip to help twist the bowl from the filter head. A safety by-pass valve set at 50 psid ensures protection of the element and helps maintain flow before element change-out is required. Mounting is simplified with four mounting holes
