Dear Mr. Riechel:#This responds to your July 1, 1974, letter concernin Volkswagen's petition to exempt its pre-bent vacuum hose from some requirements of STandard No. 106-74, *Brake hoses*. You requested that we confirm that an in-line vacuum check valve is not regulated under the standard, and that the standard's use of 'light duty' and 'heavy duty' vacuum hose terminology corresponds to the use of those terms in the SAE Standard J1403a. We respond to the Volkswagen petition in a letter of July 2, 1974, to Mr. J.W. Kennebeck of Volkswagen.#You are correct in your conclusion that an in-line check valve like the value in Volkswagen's pre- bent vacuum line is not a brake hose fitting subject to the requirements of Standard No. 106-74. #The National Highway Traffic Safety Administration tends to make the same distinction between light and heavy duty vacuum hose types as is made by the SAE Standard J1403a, which is based in the thickness of the hose wall. In addition to those sizes listed by the SAE we have added 9/32-inch hose.#Yours truly,Richard B. Dyson,Assistant Chief Counsel;
