Description
Reducing Bushing (Male x Female) NPT - SS 316
The PRBN is a reducing bushing (male x female) NPT that steps a larger port down to a smaller thread, removing the need for a second adaptor. Connections are Male x Female NPT. The 316 stainless steel body resists corrosion in gas, hydraulic and pneumatic service. Dimensionally interchangeable with equivalent Parker, Swagelok fittings.
