This is a custom built, "corrugated interior and exterior" vacuum hose specifically designed for use on wide range of street sweepers. It is typically used in short lengths (24" to 96") extending to the street brush on the side of the truck. Commonly seen on original equipment, it offers the heavy duty characteristics of a material handling hose with the added flexibility more similar to a ducting hose. It has good resistance to abrasion, weathering, and certain chemicals while its deeply corrugated interior and exterior permit maximum flexibility (as an example, 10" size have 3/4" deep corrugations that are 1-1/4" wide and spaced 1/2" apart). Since it must allow for considerable axial movement in a short length, it is built with 1000+ pounds of tensile strength (axial). Many custom lengths are available and all come with soft cuffs (approximately 4"-6" long) for ease of clamping. The specifications shown below are based on a 3/16" tube (NL8511), but a 1/4" tube (NL8512), a 3/8" tube (NL8513) or a 1/2" tube (NL8514) thickness is also available on request. Actual thicknesses can vary due to the unique, deep internal corrugations of this hose. As a general rule, a thicker tube results in added abrasion resistance but less flexibility. OEM vacuum hose crossover available upon request.

Construction: Tube: Corrugated, abrasion resistant rubber (NL8511 is 3/16", NL8512 is 1/4", NL8513 is 3/8" & NL8514 is 1/2"). Cover: Black, corrugated abrasion and weather resistant 1/8" thick SBR rubber. Reinforcement: 3-plies of fabric reinforcement with a steel wire helix.

Typical Fittings: This hose is typically attached directly to the street sweeper, N70-C202 strapping or N51 double bolt clamps.

Temperature Range: -40°C (-40°F) to +88°C (190°F); but depends on application

Cut Method: Sawzall or Hacksaw & Side Snips for Wire-Wear Safety Gloves
