I <br /> t <br /> i <br /> 3 <br /> Penetration Fittings <br /> Penetration Fittings <br /> Early on Environ acquired the"Brancher"patent for a studded penetration fitting. Environ built their product j <br /> offering around this concept and developed a loyal following of installers. Those trained by Total Containment were !' <br /> loyal to the threaded style of penetration while those trained by Environ were loyal to that product offering. There ! <br /> seemed to be no compromise or crossover between the two philosophies. <br /> qt­ <br /> Typical Environ Studded Typical Total Containment <br /> Penetration Fitting Threaded Penetration Fitting <br /> Environ manufactured a complete line of penetration fittings designed for their Corrugated Ducted Systems,their <br /> Direct Burial Flex Pipe,Fiberglass Pipe and Rigid Conduits. The Environ penetration fittings was manufactured out of <br /> Nitrile rubber and has had massive failure rates. Environ never developed a satisfactory repair system for their failed <br /> penetrations. <br /> Environ's penetrations Included: <br /> GDB series for their Corrugated Ducted Systems <br /> FEB 8000 series for 6"FRP Pipe <br /> FEB 7000 series for the 4-6"OD family of pipes - <br /> FEB 6000 series for pipes up to 3.5"in diameter <br /> FEB 3000 series for Rigid Conduits <br /> FEB 3075A Miniature and CEB 3075 Sub-Miniature W Rigid Conduit Fittings <br /> vrc�alsFr � s vc �s � e W. <br /> Nit <br /> i <br /> } <br /> FEB Series (Flexible Entry Boot) <br /> it may be difficult for the technician to be able to identify the difference between an Environ studded penetration j. <br /> and an APT penetration fitting. In general the metal securing ring used by Environ was narrower that those supplied I <br /> by APT on similar piping applications. The stud pattern on Environ and APT however,are identical. The OPW Pisces a <br /> penetrations had a smaller stud pattern and a different metal securing ring. The Diversified/Weaver and Blueline <br /> securing rings were over molded plastic and are not easily confused with those of Environ or APT. <br /> Note the differences in size of the securing plate for the 4 stud products. <br /> 1 <br /> o .®. <br /> Environ CEB 3475 Environ FEB 3075A Environ FEB 3100 APT 4 Stud <br /> Ring=.50"wide Ring=.50"wide Ring=.75"wide Ring=1.12"wide <br /> Stud to Stud=1.58" Stud to Stud=1.77" Stud to Stud=2.29" Stud to Stud=2.30" <br /> i <br /> i <br /> Diversified Products Manufacturing Inc.Environ Repair Manual Full Version Rev 3 Page 5 of 70 <br /> i <br />
