Dear Mr. Netzer:

This responds to your September 19, 1984 letter to Mr. Vern Bloom of the National Highway Traffic Safety Administration (NHTSA) concerning Federal Motor Vehicle Safety Standard No. 106, Brake Hoses. Your letter was referred to this office for our reply.

You asked whether Standard No. 106 would permit the manufacture of an air brake hose for use with permanently attached end fittings when the size of the hose is not listed in Table III of that standard. The answer to your question is yes. Table III of Standard No. 106 specified dimensional requirements for air brake hose intended for use with reusable end fittings. The table does not limit the sizes of hoses used with permanent fittings.

He wish to emphasize that all other requirements applicable to air brake hoses which are found in Standard No. 106 would apply to your air brake hoses.

Sincerely,

Frank Berndt Chief Counsel

Mr. Vern Bloom U.S. Department of Transportation NHTSA NRM11 CAD 400 7th Street, Southwest Washington, D.C. 20590

Dear Sir:

We, as air brake hose manufacturers, have been requested by several customers to produce an air brake hose having an inside diameter as listed under SAE J1402 table "A" specification for permanently attached fittings. We find that the DOT 106 specification table "III" does not list a hose diameter for permanently attached fitting and would like to know if we would have any problems if we manufactured a hose with the dimensions as listed in SAE J1402 table "A".

Thank you very much, I remain

Very truly yours,

A. F. Netzer Hose Development Manager AFN/jah
