• <br />B-18-3 Compression Fitting -PRODUCT <br />BRASS PLUG <br />B-18-3 Vulkem Seal <br />VULKEM <br />B-18-3 orientation <br />The brass secondary line test plug located <br />within the body should be at a 90° degree <br />angle from any flat wall. If it is at any other <br />angle, the fitting is not installed correctly <br />and/or the gasket is not flat against the floor. <br />Whether the gasket is seated firmly to the floor <br />or not, or if the orientation is incorrect, the <br />Vulkem sealing method outlined below is the <br />best way to make a lasting liquid -tight seal. <br />When pressure -testing the secondary: the <br />top nut makes this seal. The Brass plug should <br />not be removed. If leaks occur from the top <br />nut/donut then loosen them with WD -40 if <br />necessary and re -seat with wet -dry grease. <br />Then tighten the nut no more than 1/4 - 1/2 <br />turns past hand tight. <br />WARNING! The lower nut of the <br />B-18-3 fitting must not be loosened without the <br />compression donut securely sealed against <br />the pipe. The uper nut holds the donut secure. <br />If both are loosened too much the B-18-3 <br />fitting body may drop down or fall through the <br />bottom of the shallow pan. <br />After cleaning all contact areas thoroughly, use <br />vulkem to seal between the bottom nut and flat <br />gasket. With the top nut secured to the pipe, <br />loosen the lower nut and apply vulkem under <br />the nut and generously to the exposed threads <br />of the body. Do not dislodge the flat gasket or <br />apply vulkem between it and the floor of the <br />shallow. Lubrication can cause it to slip loose <br />or pinch once tightened causing a leak point. <br />3 ii -B2000 -RETROFIT -KIT -14A <br />
