My review is for a double acting, 6 qt. Steel tank unit.Unit arrived as described (for the most part, more on that later). Well packed in a box that appears dropped shipped. The unit appears to have a small slathering of some type of packing grease or oil to keep it from corroding. All parts are intact and nothing missing.Tank welds all appear to be properly done, no leaks as of yet. The unit works as intended. Fat red lead to battery positive. Fat black lead from stud on body of motor to battery negative.I deducted a star because of the description for these hydraulic units are all misleading. The fittings are not SAE - but rather 1/4” BSPP - British Standard Parallel Pipe fittings. They are NOT NPT. While 1/4” NPT may “fit”, the threads in the body of the unit are parallel or “straight” threads vs. tapered. Parallel threads are more common in hydraulic systems because they rely on a gasket or o-ring to seal and tend to be more serviceable than tapered threads which rely on crushing threading surfaces, possibly causing thread damage, to seal properly. While you can force fit a tapered thread into the parallel thread and use some Teflon tape or sealant, you’re better off doing it right and getting an adapter and not damaging the threads. Yes it is added cost, but that’s a part of DIY!You can get BSPP to “your fitting” adapters from a number of places online if you can’t find what you need here on amazon or your local hydraulic shop. I spent about 10 bucks for two fittings to adapt from the fittings on the unit to my application which made things much easier. If you don’t know what you’re doing, your local hydraulic vender will gladly take your money to get things going for you.
