RFCFIVED <br />Ji',JiIZ017 <br />ENVIRONMENTAL HEALTH <br />CERARTMENT <br />Secondary Containment Fittings <br />Available secondary containment fittings are tees, 90° elbows, <br />45° elbows, couplings, crossover nipples, concentric reduc- <br />ers, termination fittings (with or without 3/4" NPT threaded out- <br />let), and sump entry termination fittings. Inserts are required <br />on 3" (75 mm) and 4" (100 mm) 90° elbows and tees for <br />Closed Systems (capable of Interstitial Monitoring). Inserts are <br />not required for Open Systems. <br />Adhesive for Secondary Containment Piping <br />When joining secondary containment pipe -to -fittings, fiber- <br />glass filler must be added to the 7000 or 8000 series adhesive <br />to ensure optimum performance of this type of bonded joint. <br />PSX adhesives do not require fillers. <br />Filler is available from Fiber Glass Systems. Due to the quan- <br />tity of adhesive required for joining secondary containment <br />fittings, it is recommended that only 7069 or 8069 kits be <br />used for Red Thread IIA systems and 8 oz. PSX•34 for Dualoy <br />3000/1- systems. If 7014 and 8014 kits are used, please note <br />that extra kits (50% more than 7069 or 8069) must be used for <br />each secondary containment fitting. <br />42 <br />
