The accessory covers are designed to be added onto couplings to "softens" the edges of quick connect couplings, making them non-abrasive and less likely to cause damage to surrounding components and surfaces. In addition, the covers also protect couplings from impact, prolonging the service life of the couplings. For protection on both front and back part, order specific product number in eSafe series 300, 310, 315, 320, 410, 430 and 550. The accessory covers comes in a pack of 10 pieces with an instruction. For easy installation, order assembly tool separately. The covers fits the standard eSafe series 300, 310, 315, 320, 410,430 and 550.
