Uniweld RHP400 Nitrogen Regulator - Delivers Up to 400 PSI of Pressure

Loadtoad: For the price, it does its job. Seems kind of lightweight and delicate, but if I take care of it, it should last for years. If I was a professional and used it daily, I might spend more money and get a solid good quality unit. But for the hobbyist, this is fine.

Darcy D Reed: If you are looking for gauge accuracy this is not the regulator for you. it works ok for low pressure use. If you're looking to use it at 200 psi or above the out flow pressure gauge sticks/hangs. It also reads about 50 psi higher on the same gauge. The regulator pressure adjustment seams to work as advertised. Since I'm using this set up on a nitrogen tank used to fill tires it's not a big issue in conjunction with an accurate tire pressure gauge, however if I was going to use it on my Mig tank I would be seeking a replacement. Just my thoughts.

Ballyerboy: It works properly like my oxy acetylene gauges. A bit more expensive than some but I figure it’s worth it for the lack of hassle

V3ry5ick: Great value for the $$. Cheaper than the local supply house. I have blown out hundreds of A/C drain lines so far. I always unload the regulator to keep it from pegging when I turn my tank pressure on. Thanks!👍

EHSAN M.: The item arrived in disgusting "open-box" condition. Taped by hands on the corners on the plastic wrap. I'm almost certain someone pushed the gauge inside the plastic cover (who knows in what condition) and taped the corners so it doesn't fall. No respect whatsoever for the customer who paid for supposedly a brand-new/factory sealed gauge.

CENTINELA HVACCENTINELA HVAC: No doy las 5 estrellas debido a que salió el manómetro de alta con unos raspones por dentro , el manómetro de salida tenía rebabas cerca de la aguja , de ahí en fuera trabaja muy bien.
Por el.precio no creo encontrar algo mejor.

Houckster: I was hesitant to write a review on this product because I have virtually no experience with this but then I thought that the experience of a newbie might be worthwhile.

Last year, I converted to nitrogen for both my truck and bicycle tires. I bought all the stuff I thought I'd need but the pressure regulator soon proved itself to be a PITA. The dial was small and when fully tightened, the gauge faced down making it difficult to read. The Uniweld RHP400 was my solution.

When attaching the regulator to the tank, you can position the gauges to the needed angle before the final tightening. Also, for those who are new to this stuff, the two gauges are very nice. The right gauge tells how much pressure is in the tank and the left gauge tells you the output pressure. Finally, there is a fitting on the bottom of the unit in the picture. If you're using a 1/4" hose, it must be removed. Believe me, it's on there tight but it's easily removed if you mount the regulator on the tank first and then use a good tight-fitting wrench to remove it. Be careful because the fitting is brass and the flats can be easily rounded off.

It took a few minutes of fiddling with the value...
