RaceFlux's RH8 Viton rubber push-lock hose makes plumbing your vehicle easy. This SAE J30 R9 rated hose features a Viton Fluoroelastomer (FKM) inner layer for compatibility with nearly all automotive fluids including fuel, engine oil, gear oil, transmission fluid, coolants, water, air and vacuum. An embedded aramid fiber braid serves as reinforcement while an outer layer made from Epichlorohydrin (ECO) rubber gives it a much higher maximum operating temperature than Nitrile rubber.

Certified for use with racing fuels, ethanol-based fuels (E85+), diesels/bio-diesels, methanol, and ethanol/gasoline mixtures. This hose will not deteriorate, dry, harden, or permeate fuel (emit fuel vapor) with the presence of ethanol in gasoline.

May be used with RaceFlux and other brand push-lock or hose barb fittings.

Please note: Hose clamps (i.e. worm-gear or Oetiker ear clamps) are REQUIRED when:

  1. Using smooth hose barb fittings
  2. Using push-lock fittings with an operating pressure above 10 psi

Failure to install a hose clamp when necessary will likely result in failure and/or serious damage (i.e. a hose backing off the fitting). 

Sold in 6.5 ft (2 meter) lengths only.
