Combi nuts - sometimes known as carp nuts, these combine a plain or domed washer assembled into a hexagonal nut
so saving time, operations and loss of washers.
Connectors are fixed from the rear of the panel with a hexagonal nut
. The reduced footprint design with a-coding is offered in 4-, 5-, and 8-pin versions.
The hexagonal nut
of the end cap is made smaller so that the heater housing will pull off the nozzle and clear the tip end while leaving the end cap and tip in place.
Expander connectors and end caps are in black polyamide with the two connector parts connected together by means of pins which are housed in special counter-seats - two tapered cavities inside the connector are provided for housing a hexagonal-head screw or a hexagonal nut
. Thanks to this tapered shape the connector exerts a pressure on the inner walls of the tube as the screw is tightened into the internal nut, thus ensuring the tensile strength of the connection.
