Vortex Recoil plungers are the same as a standard vortex plunger but they are designed with an integrated spring and nogo. The recoil design feature eliminated the need for a bottom hole bumper spring. Vortex Recoil plungers are machined to length, weight or OD required. Vortex Recoil plungers handle solids and work well in sand and paraffin applications. Rifling on the plunger allows the plunger to spin which results in equal wear throughout the life of the plunger.
