Nicopress Sleeves
The 428 series oval sleeves are made from special materials and are specifically designed for use with stainless steel aircraft cable. The tin plating gives this Nicopress sleeve a distinctive appearance.
Nicopress have determined through pull testing that copper and plated copper Nicopress oval sleeves will hold military specification grade aircraft control cable in tension until it breaks, when the cable is made to military specifications; MIL-W-83420, dated 9-7-73, for cable constructions 3x7, 7x7, and 7x19, and MIL-W-1511A-4 dated 2-20-64 and MIL-W-5424B dated 1-10-72 for cable constructions 6x19 IWRC.
However other types and grades of cable exist and may be used with Nicopress sleeves. In order to establish the exact holding power of a Nicopress sleeve when used with other types of cable, Nicopress recommend pull testing prior to use. This step ensures the proper selection of materials, the correct pressing procedure, and an adequate margin of safety for the intended use.
