I used it on machine that discharges nitrogen through 5 mm nozzles and pressure drops quickly Review: Decided to Nitrogen test an A/C leak on my 2017 Ford Expedition. As soon as I pumped the Nitrogen in, the hissing sound started. Found the leak within seconds. Worth the money, solid construction, easy to use instructions. I would recommend this unit to anyone who needs a nitrogen test kit for their automotive use. ## Features - 1/4" SAE flare output, with control valve - T handle for ease of pressure adjustment - 2 1/2" gauges with guards - High pressure gauge 4400 PSI - Low pressure gauge 1000 PSI ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00DKWGGD0 | | Best Sellers Rank | #95,541 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #13 in Welding Gas Regulators | | Brand Name | MASTERCOOL | | Country Of Origin | USA | | Customer Reviews | 4.7 4.7 out of 5 stars (163) | | Global Trade Identification Number | 00700376530018 | | Included Components | MASTERCOOL - Nitrogen Leak Test Regulator (53001) | | Item Dimensions | 30.5 x 35.6 x 10.2 centimeters | | Item Type Name | Test Tool | | Item Weight | 3 Grams | | Manufacturer | Mastercool | | Material Type | Silver | | UPC | 700376530018 | ## Product Details - **Brand:** MASTERCOOL - **Item dimensions L x W x H:** 30.5 x 35.6 x 10.2 centimeters - **Item weight:** 3 Grams - **Material:** Silver - **Thread type:** 1/4" NPT ## Images ![Mastercool (53001 Silver Nitrogen Pressure Regulator - Image 1](https://m.media-amazon.com/images/I/715t57bhqnL.jpg) ## Available Options This product comes in different **Model** options. ## Questions & Answers **Q: How many pounds of pressure will this have at the output?** A: Great question!
