Rated 4.9 out of 5 by 9 reviewers.
Rated 5 out of 5 by If this machine is as great as its predecessor it will be a great machine. This is the second one of these we have had. I have been at Indiana State University for 35 years and the Model 300 Compact Threading Machine we are replacing has been at the university longer than I. It is a great machine. Jim Gregg December 16, 2014
Rated 5 out of 5 by We especially enjoy the portability. We went from (and still own) the model 690 portable on all our smaller jobs, although a very robust and easy to manage tool it becomes tiresome with all the details of clamping, cutting and threading. The 300 compact has reignited our passion for pipe threading with its ease of use. The only draw back is during transport the sump leaks oil in the vehicle. Not sure if we are missing some details, we believe we are inserting the sump blank off plate properly. We have tried elevating the handle end and oil still finds it's way onto the floor in the Van. If this is the only problem we experience I am certain we will fabricate a nice support stand and call things good. December 14, 2014
Rated 5 out of 5 by Excellent portable machine for the price! Great machine in a compact package made to be moved around and used in the field with ease. November 28, 2014
Rated 5 out of 5 by The product is perfect hands down There is no complaints about anything, beats anything else on the market, and its getting what you pay for. Worth it November 28, 2014
Rated 5 out of 5 by Construction Superintendent We are an Industrial Refrigeration contractor and have used Ridgid piping equipment exclusively since my apprentice days.... some 41 years ago. Your product lines have come a long way since the drop head die and ratchet era. All our power vises, tripods, chain vises, pipe wrenches, dies, cutters and reamer continue to be Ridgid, our only choice in tools for our industrial market. To be honest, we've never considered using anyone else's product. Keep making high quality equipment.. November 25, 2014
Rated 4 out of 5 by a great machine, except for the plastic parts that easily get broken due to their location on the machine. for example the forward/reverse switch has been replaced about 3 times, the power and foot cord are forever coming out of the housing. other than that it runs and works like a horse. November 25, 2014
Rated 5 out of 5 by easiest threader to use I have own this threader for 3 years now. It's by far the best threader I've used November 24, 2014
Rated 5 out of 5 by Very well built product! We have used this product for many years now. It has been very depenable, easy to use and reliable. The best on the market. November 24, 2014
