RECOMMENDED BRUSH SIZE FOR PRIMER AND CEMENT APPLICATIONS Nominal Pipe Size Brush Width IPS a 3 B CM USE ONLY NATURAL BRISTLE 3 MAKING THE JOINT A Cutting Pipe must be squarely cut to allow for the proper interfacing of the pipe end and the fitting socket bottom This can be accomplished with a miter box saw or wheel type cutter Wheel type cutters are not generally recommended for larger diameters since they tend to flare the corner of the pipe end If this type of cutter is used the flare on the end must be completely removed NOTE Power saws should be specifically designed to cut plastic pipe B Deburring Use a knife plastic pipe deburring tool or file to remove burrs from the end of small diameter pipe Be sure to remove all burrs from around the inside as well as the outside of the pipe A slight chamfer bevel of about 10 15 should be added to the end to permit easier insertion of the pipe into the end of the fitting Failure to chamfer the edge of the pipe may remove cement from the fitting socket causing the joint to leak 3 32 2 5MM x STEPB C Test dry fit of the joint Tapered fitting sockets are designed so that an interfaced fit should occur when the pipe is inserted about 1 3 to 2 3 of the way into the socket Occasionally when pipe fitting dimensions are atthe tolerance extremes it will be possible to fully insert dry pipe to the bottom of the fitting socket When this happen
