D. Termination Fittings E. Termination at the bulk tank connections is accomplished by using a termination concentric reducer with 3/4" female NPT threaded outlet. (See Figure 5) Tank Fiberglass Threaded Adapter (Bell x Male) O O O 3/4" NPT O 1 O O Figure 5 Termination at the dispenser is at the end of the fiberglass containment piping and is accomplished using a termination concentric reducer. (See Figure 6) Dispenser Impact Valve Fiberglass Threaded Adapter (Bell x Male) Galvanized Steel Figure 6 Bonding and Assembly (For Containment Piping) Use only DS -7014, DS -7024 or DS -706 adhesive manufac- tured by Smith Fiberglass for installation of Smith Fiberglass containment piping systems. The number of 3" containment fittings which can be bonded from one DS -7014, DS -7024, or DS -7069 adhesive kit is shown in Table III. TABLE III Bonding of Containment Fittings NOTE: Information for 4" and 6" diameter fittings not available at present time. Refer to bonding procedures in Manual 1055 for adhesive mixing and surface cleaning. After cleaning all sanded surfaces, apply a thick coating (1/16" minimum) of adhesive to the socket (bell) area of the fitting. The stir stick supplied with the adhesive kit works well as an applicator. Liberally coat the tabs (flat bonding surfaces) of both halves of the fittings with adhesive (1/16" minimum thickness). Apply a thick coating (1/16" minimum) of adhesive to the sanded surfaces of the pipe ends. NOTE: Two-piece containment fittings require more adhe- sive used with Smith Fiberglass bell and tospigot joints. Use the bolts, nuts and washers to assemble the fittiriy: - the pipe. Two 7/16" wrenches are required for the bolts. Note that a flat washer is required on both halves of the fittings. (See Figure 3) Tighten the nuts and bolts completely. Make sure that adhesive fills any gaps between pipe ends and fitting sockets (bells). Termination on the shear valve (impact valve) may be accom- plished with a flexible hose, clamped and bonded in place. (NOTE: Not supplied by Smith Fiberglass.) (See Figure 7) Dispenser Impact Valve Gasoline Resistant Boot Flexible Connector Figure 7 3 Care should be taken not to disturb the containment piping joint when assembling additional joints. The adhesive must be fully cured before applying stress to assembled joint. Use adhesive as thread sealant for NPT threads on termination fittings.
