30 Series Parker No-Skive Fittings is a field attachable (reusable) style fitting which permits quick, easy field assembly without special tools. Assembly of No-Skive hose and fittings does not require removal of outer cover of hose. This eliminates premature hose failure caused by skiving too long or short. 30 Series Fittings has zinc dichromate plating and are used with 301 , 381 Hoses - the Parker Hydraulic/Braided Hoses.
