Introduction
This section specifies the general requirements for securing hoses and electrical wires to present an orderly appearance,
facilitate inspection and maintenance, and prevent potential damage to these lines.
Definitions
Bundle: Two or more air, electrical, fuel, or other lines tied together to form a unitized assembly .
Clamp: A cushioned rigid or semi-rigid, anti-chafing device for containing the bundle and securing it to the frame or other
structural support. Standard clamps have a black elastomer lining. High temperature clamps (e.g., those used with com -
pressor discharge hose) have a white or red elastomer lining (most applications for these are called out in the bills of
material). An assembly of two clamps fastened together to separate components is referred to as a “butterfly” clamp. Note:
the metal portion of clamps shall be stainless steel or otherwise made capable, through plating or other means, of passing
a 200 hour salt spray test per ASTM B117 without rusting .

to otherwise secure hoses and wires as noted below . These straps must be UV stable .
FIGURE 9-3. Tie Strap
Heavy Duty (HD) Mount: A black rigid device used for securing a tie strap to the frame or other structural support.
Mounts are made of impact modified, heat stabilized UV resistant nylon capable of continuous operation between tem -
peratures 220°F (150°) and -40°F (-40°).
