Green Duo Piston
The Green Duo Piston is a bonded dual durometer piston that is highly resistant to abrasion and tear. The bonded construction resists extrusion under pressure and restricts movement to reduce the build-up of heat.
The Green Duo Piston is recommended for systems with oil or synthetic based mud. It is also recommended for water based mud when weights are 11 lb/gal or over. The Green Duo Piston is not recommended for clear water or seawater pumping due to the lack of lubricity of these fluids.
