Drive tools for polyethylene fittings come in a number of sizes. Each size and type of fitting requires a specific driver. Driver arbors are installed in electric router chucks. The fittings are not hard to install, but you must have the correct tools and we strongly advise practicing on a scrap of thick polyethylene before trying it on a valuable tank. (See our notes below.)

We normally keep the the above sizes in stock. Other sizes available upon request. Please call us if you are installing other types of fittings.



When selecting location for fitting, it is best to have a flat spot on the tank where the entire flange is on the flat surface and the fitting and tool can spin freely.

First, cut a proper size hole with a hole saw. Drill a hole in the tank that is slightly larger than the pilot on the fitting so that it is not binding but also not sloppy in the hole.

Choose the proper size router for the job. On fittings up to 1/2", you can use a 1 HP router. On fittings measuring 3/4'' to 1-1/2'', a 1-1/2 HP to 2 HP router is acceptable. On fittings 2'' and larger, you'll need a beefy 3 HP router of at least 14 amps. Drivers for 1/2" fittings will have 1/4" shanks. Drivers for all other fittings have 1/2" shanks. Do not use a pneumatic router. Use an electric router capable of 18,000 to 25,000 RPM's. Do not attempt to spin weld with a drill press or hand drill because you cannot reach the proper speed.

Place the fitting pilot in the hole of the tank. Holding the router in your hands and having the driving tool attached to the fitting, turn on the power and apply slight pressure so that molten plastic starts to flow around the entire outside diameter of the fitting. You will develop a technique as to how to apply pressure. The melting process will only take 2-3 seconds. When you have a good 1/4" bead of molten plastic around the perimeter, turn off the power and keep the driver in position with applied pressure for another 5 seconds. This will ensure a good bond.

After 1 full minute you can apply testing procedures, such prying with leverage.
