Review on Beduan Reducing Fitting Reducer Splicer Hydraulics, Pneumatics & Plumbing by Vincent Poolaw

I couldn't find the size I needed at the hardware store to connect the water cooler and K40 laser so I ordered them here. I don't have a price to compare so I can only assume it's a good price compared to other brands/sellers who are almost getting 2 for 1. Personally it's very expensive for something so small, but I think it's considered an extra size so we pay extra. In any case, fit and quality are important to me. It works great by firmly connecting 2 different pipes together without clamps.
