Internal Hi-Lo gage. Four quick steps check internal alignment
You can check the internal alignment of your fit-up quickly with the HI-LO Gage.
1. unlock the retaining screws. Press the gage legs beyond the barrel.
2. insert the legs ( wires ) into the root gap space of the two pieces of pipe to be fitted. Turn the gage 90 º, being careful to apply a constant back pressure to the barrel.
3. Hold the gage as square as possible with the fitting to obtain an accurate reading. Lock the retaining screw, Reverse the 90º turn and remove the gage. You've now ready to read the increment opposite the red line.
4. When the red line aligns with the 1/32 increment you have a good internal alignment and fit-up. Misalignment can be determined from the zero line by increment markings of 1/16 inch.
Rootweld spacing gage. Easy operation determines rootweld spacing.
1. Unlock the retaining screw and insert the gage interior alignment stops between the two pieces of pipe to be fitted.
2. Insert the leg with the long taper into the root gap until it makes contact with both sides of the gap.
Relock the retaining screw, remove the gage and read it.
3. The scale is calibrated in fractional dimensions from 1/32 to 3/16 inch in 1/16 inch increment markings. The readout you receive represents the amount of the rootweld gap.
