22、following services. 1.2 A swivel connector is either a hose swivel or joint swivel. The swivel connector will allow radial movement and shall be constructed for use with the uids shown in 1.4. 1.3 An emergency breakaway tting is used between the outlet of the dispensing device and the hose nozzle va

23、lve and separates in the event that the coupling is subjected to an excessive pull force to safeguard against abnormally excessive pull force on the hose assembly and dispenser and prevent loss of liquid. An emergency breakaway tting shall be constructed for use with the uids shown in 1.4. The tting

24、s shall be of the single-break or reconnectable type. 1.4 Emergency breakaway ttings, swivel connectors, and pipe-connecting ttings are intended for use with one or more of the following as applicable: a) Diesel fuel and diesel/biodiesel blends with nominal biodiesel concentrations up to 5 percent (

The numerical value corresponding to the biodiese

38、l component determines the blend rating (such as B20 for 20 percent biodiesel, 80 percent diesel). 3.3 FITTING, PIPE-CONNECTING A tting of the threadless compression seal-ring type for use in the assembly of dispensing devices to facilitate connection of piping or tubing. These ttings shall be made

39、in the straight coupling style, as well as in the tee, ell, reducer, adapter, and other styles. 3.4 FITTING, RECONNECTABLE TYPE An emergency breakaway tting designed such that upon separation it is intended to be reconnected and reused when it is not damaged. 3.5 FITTING, SINGLE-BREAK TYPE An emerge

40、ncy breakaway tting that, upon separation, is not intended to be reconnected and reused. 3.6 HOSE SWIVEL A swivel connector with one end attached to a hose and the other end to an appurtenance. The hose swivel will allow radial movement of the hose and/or appurtenance to prevent the hose from twisti
