    Ensure an even seal around your flange—these tools align and level flanges in a single step. The strong magnets make sure your bolt holes are perfectly inline horizontally and that your flange isn’t tilted. If your flange is made of stainless steel or another nonmagnetic material, secure these aligners using the included threaded cones.

    No-Strike Hex-Head Alignment Pins for Flange Bolt Holes

    Image of Product. Front orientation. Contains Annotated. Alignment Pins. No-Strike Hex-Head Alignment Pins for Flange Bolt Holes.
    The tapered shaft of these pins eliminates the need for hammering and prying when aligning flange bolt holes. To align bolt holes, fit the tapered end of the pin into the bolt holes and use a wrench on the hex head to rotate and align the holes. If your bolt hole is in between the sizes listed, choose the smaller size pin.

    Each step on these aligner pins matches common bolt holes on pipe flanges, so they're more precise than conical aligner pins and don’t require nuts. Press the pair of pins into mated flanges to make sure the flanges are aligned. Once two sets of holes are aligned, you'll know the rest of the holes are as well. Made of durable chrome-plated steel, they'll hold their shape over time and resist rust.

    Hydraulic Alignment

    Align flanges on heavy pipes when alignment pins don't fit through the flange holes. Often used for pipefitting, welding, and maintenance, these kits make it possible to correct angular and offset misalignment on a range of pipe sizes.
    Choose an alignment mechanism based on how much force you need to move the pipe. If you're not sure, measure the flange hole diameter—it correlates to the pressure class and size of your pipe. Larger pipes typically require more force.
    Hand-Crank Alignment—Hand-crank aligners are best for routine maintenance and quick repairs. As you turn the hand crank, it moves the pipe.
    Ratchet Alignment—Ratchet aligners produce four times as much force as hand crank aligners. Position the tool's arm through a flange hole on the pipe you plan to move, and place the lead screw on the edge of the stationary pipe's flange. Wrap the strap around the pipe you plan to move. As you rotate the lead screw with a wrench, the misaligned pipe moves into position.
    Hydraulic Alignment—Hydraulic aligners are best for severe misalignment—they generate over twice as much force as ratcheting aligners. Position the tool's arm through the flange hole on the pipe you plan to move, and place the lead screw on the edge of the stationary pipe's flange. Wrap the strap around the pipe you plan to move. As you press down on the hand pump connected to the lead screw, the pipe moves.
