### ⭐⭐⭐⭐⭐ Good quality
*by T***H on September 6, 2024*

Ordered these to adapt out a pneumatic filter for my compressor. Rated to 1200psi (not going to be anywhere near that value!) but being used to 175psi. All machine work was very well done, no jagged edges or burrs. The threads were cleanly cut and of proper pitch for each size. Assembled with ease and no problems with fitment. Nice product.
