Q. "How do these clamp over the pipe?"
A. You just open the saddle, place it around the pipe and attach the easy clamping hinge. Apply the wedge half way by hand and finish it off with a slight tap of a rubber mallet. Now you are ready to turn the cutter clockwise with a socket wrench. Simple, easy and fast.
Q. "Will these hot/wet taps work on ABS pipe?"
A. Yes, the manufacturer has tested the FLO TAP and verified that it works on ABS pipe.
Q. "If I unscrew the cap on the tool port can I remove the cutting tool and thread a regular pipe thread fitting onto it or a regular pipe nipple inside of it?"
A. No. The threaded cap that fits on the outside of the tool port is slightly larger than 1-1/2" NPT, but much smaller than 2" NPT. The threading inside the tool port has special fine threads (much finer than NPT threads). Regular NPT pipe threaded fittings or pipe nipples will not connect with them. The tool and cap that comes with the saddle are the only fittings that will fit inside or onto the outside of that port.
Q. "Why did the manufacturer use fine threads on the tool port instead of using regular pipe threads (NPT)?"
A. By using finer threads for the cutter tool better torque pressure could be applied and cutting or shaving the plastic is done in smaller increments making the cutting of the plastic smoother and the tool easier to rotate. These internal fine threads also keep water from escaping through the tightly fitting tool during the cutting process so it can be used without turning off the water. The threads on the outside of the tool port allow the cap to be hand tightened and sealed with the o-ring as a secondary leak prevention once the tool is positioned to the top of the port.
