Secondary grease lines and couplings
5.7.1
Grease line types
The secondary grease lines are the ones between the distribution blocks and the grease points.
These grease lines are connected to the grease points with the aid of special couplings. A wide
variety of couplings is available.
Which types of couplings should be applied depends, among more things, on:
•
The screw thread at the greasing point.
•
The position of the greasing point.
•
The direction from which the grease line approaches the grease point.
•
The type of grease line employed (polyamide lines with brass or steel couplings; metal lines or
high-pressure lines with steel couplings).
•
The operation conditions.
The secondary grease lines can be supplied in a number of different sizes and
materials:
•
Polyamide lines with outside diameters of 3/16" or 6 mm (standard).
•
Stainless steel lines with the outside diameters of 3/16" or 6 mm (standard).
•
Kunifer (copper/nickel) lines with outside diameters of 3/16" or 6 mm (standard).
•
Flexible high-pressure lines with inside diameters of 4 mm or 6 mm (1/4").
The type of secondary grease line most commonly used in the transport industry is the polyamide
line with an outside diameter of 3/16” or 6 mm. These grease lines are supplied as composite lines.
In a composite line 2 or 3 polyamide lines are held together by a single plastic jacket. Each grease
line in such a composite line has its own colour (red, blue or black), so that they can be easily
distinguished at the ends of the composite line (necessary for easy installation and maintenance).
If a composite line is connected to doser segments with different grease outputs, the individual
grease lines should be connected as follows:
•
Doser segment with the lowest output
Red line
•
Doser segment with the highest output
Black line
•
Doser segment with intermediate output
Blue line
