In the Soft-Line range, three accessories are included; accessory covers, assembly tool and kink protectors. 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. The covers can be fitted on any regular series 300, 303, 310, 315 and 320 coupling An assembly tool is delivered with the covers but can also be ordered separately. Kink-protectors can be used on all Stream-Line connections with the corresponding hose size. Kink protectors are sold separately and can be replaced during use with the cap nut on the Stream-Line connection.
