Horrible they lied about withstanding a pressure. I used it on machine that discharges nitrogen through 5 mm nozzles and pressure drops quickly

Well Built Nitrogen Regulator
This nitrogen regulator is solidly built and easy to use. The gauges are glycerine filled and have a smooth motion for reading pressure. All the knobs turn easily.

Regulador de gas nitrógeno
Compré este equipo para presurizar equipos minisplit, funciona bien, viene con su manual de uso en varios idiomas incluidos español e inglés. Los únicos detalles que le veo son la rosca que conecta con el cilindro y la salida macho de 1/4, no se me hacen “muy sólidas/resistentes”, creo qué hay que tener cuidado para que no se lleguen a romper. Aun así me quede con el artículo por la calidad de la marca. Otros detalles fueron que le tuve que poner Teflon a la rosca que va al cilindro ya que presentaba fugas en ese área y en la salida de 1/4, les comento que es la primera vez que uso este artículo, tal vez me falta “acostumbrarse” a su uso y evitar esos detalles, nada grave, ya que el nitrógeno es un gas inerte y pues lo uso en espacios abiertos. Todo bien por parte de Amazon USA, envío puntual.

Solid Regulator, but My Amazon Resale Unit Had Issues
I picked this regulator up from the Amazon resale market. Unfortunately, there was a good reason it had been returned. The unit I received was listed as "like new," but it arrived in a condition that made it unusable for my needs. That being said, the regulator itself appears to be well built and durable. It has a solid, heavy feel to it, which gives the impression that it is designed for professional use and long-term reliability. The gauges are easy to read and provide clear, accurate-looking measurements. I was disappointed with the condition of the item I received, but that issue may be more related to the resale listing than the actual product. Based on the construction, weight, and gauge quality, the regulator seems like it would be a good piece of equipment when purchased in proper working condition. If you're buying new, your experience may be much better than mine. Just be cautious when purchasing through resale channels and inspect the unit carefully upon arrival.
