Vacuum service is one of the most severe hose applications on a race car. Dry sump scavenge systems are often designed to pull so much vacuum that it actually affects piston ring sealing.

Standard rubber-lined AN hose requires some type of inner support or it will collapse under less than 30 inches of vacuum. This stainless steel spring is made to be a tight fit inside stainless braided or Startlite (aramid braided) hose. Simply cut the hose to length and cut the spring approximately 4" shorter than the hose. Insert the spring into the hose, then install the hose ends. Sold in 1.2 meter (4 foot) lengths.
