Parker 79 Series Fittings is a Parkrimp permanent (crimp) style fitting which permits quick assembly with our family of Parkrimp crimpers. Assembly of No-Skive hose and fittings does not require removal of the outer cover of the hose. This eliminates premature hose failure caused by skiving too long or short. 79 Series Fittings has zinc dichromate plating and are used with 792ST , 792TC Hose - Parker Hydraulic Spiral Hose.
