Those are easily identifiable by observing the shape of the nut. When ordering repair products <br /> the"Fine"or"Coarse"pattern must be specified as a different bonding ring is provided in the repair kit. Note there are four <br /> bonding ring options—FF(Flat surface Fine thread),FC(Flat Surface Coarse thread),CF(Curved surface Fine thread)and CC <br /> (Curved surface Coarse thread). Provide order entry with the correct Information and they will get you the correct part. The <br /> curved surface seal made by the original TO penetration included a curved seal on the outside of the sump and a curved <br /> spacer on the inside of the sump. As the repairs are made from the inside of the sump,the old spacer must be removed and <br /> a new bonding ring is installed in its place. The bonding ring Is used on both the traditional and Multi-sync versions of our <br /> repair kits. y l <br /> - i <br /> Fine Thread Nut Coarse Thread Nut <br /> Double Wall Fiberglass Variations <br /> When repairing double wall fiberglass pipe the FB/CB 3050 or 4050 penetrations were used for 3"FRP and 4"FRP <br /> respectively. There are two distinct repair methods used when repairing these products. When the Secondary pipe c <br /> extends into the sump beyond the fitting,a terminating reducer is used to seal the secondary to the primary for testing <br /> of the interstitial. This type of installation is common and is repaired as follows. <br /> Mise Itfhls <br /> i <br /> 3050 with secondary pipe extending Into sump <br /> i <br /> rF44O_t = <br /> Traditional Repair of FB 3050 with pipe terminating inside the fitting <br /> When the double wall fiberglass pipe in the FB/CB 3050 or 4050 is terminated inside the penetration fitting,a donut Is <br /> often used to seal to the primary pipe. This requires a different repair kit as shown below. The experienced repair <br /> technician can readily identify the difference between these repair options. <br /> { <br /> I <br /> Diversified Products Manufacturing Inc.Environ Repair Manual Full Version Rev 3 Page 63 of 70 I <br /> i <br /> i <br />
