DRY FITTING Place one-half of Containment fitting under dry fitted primary lines to measure <br />SECONDARY length of Containment piping to be cut. Cut Containment piping to allow one and <br />CONTAINMENT SYSTEM one-half inch for sealing into each fitting. Use at least one Containment coupling <br />(Cont'd) between all fittings, where practical. Use of Containment couplings between fittings <br />allows inspection of primary coupling in line and/or provides the ability to pull the <br />Containment pipe back from primary fittings for inspection during testing. <br />,' <br />rk{ <br />When crossing over lines, the 45° and 90° Containment fittings will accommodate <br />close nipples on primary piping. <br />
