PPR Series Regulators offer stable air flow with locking adjustment knob to prevent accidental setting changes. PPR Modular Series Regulators can connect to PPF Modular Series Air Filters & PPL Modular Series Air Lubricators using our brackets to form a fully functional FRL unit. PPF Series Filters and PPL Series Lubricators are available for purchase along with other Pneumatic Plus Air Preparation Units. Review: Quality product for controlled PSI - Worked as advertised and allowed for enough CFM to blow out my sprinklers while maintaining safe line pressure. Review: Updated: 2 months later it's leaking air - Update: I got in touch with Pneumatic Plus support which diagnosed the problem with me and sent a replacement. The replacement is working fine so far, so I’m revising my rating. I’m happy with the product and support. ========== Original review: Given the premium price, I bought this thinking it would be a higher-quality part. Two months on and it slowly drains the compressor tank if left on anything other than the highest pressure setting (i.e., the same pressure as in the tank). This was sold by "desertcart.com Services LLC" and the return window closed after 30 days. There's no way to contact desertcart about this, and no information whatsoever on contacting the manufacturer. Really unhappy about being out the money and having to repair this once again. ## Features - HIGH FLOW AIR COMPRESSOR REGULATOR WITH GAUGE — Reduces and stabilizes compressed air line pressure to a precise, constant downstream setpoint for air tools, spray guns, actuators, and pneumatic machinery. The 1/4" NPT inline body installs quickly into shop and production air lines and holds your set pressure steady as demand changes. - RELIEVING TYPE, STANDARD LOCKING KNOB — The relieving design automatically vents excess downstream pressure whenever it rises above your setpoint, protecting tools and delicate equipment. A push-to-lock adjustment knob holds your setting securely under vibration and prevents accidental changes on the shop floor. - HIGH FLOW RATE 86 SCFM @ 90 PSI — 1/4" NPT ports are sized for high-demand shop and production air lines, delivering consistent volume to your equipment. The fully adjustable regulating range of 0-140 PSI lets you set the exact working pressure each tool or process needs. - EMBEDDED GAUGE AND MOUNTING BRACKET INCLUDED — Ships ready to install with a built-in 0-140 PSI pressure gauge for at-a-glance monitoring and a panel/wall mounting bracket, so there are no extra parts to source. Rated for a 250 PSI maximum supply pressure for dependable everyday service. - REPLACEMENT COMPATIBILITY — Aftermarket replacement compatible with ARO R37221-600 and other ARO R37221 variants, manufactured to meet dimensional and functional requirements for proper fit and performance. Precision manufactured in Korea and backed by responsive PneumaticPlus support and a 1-year limited manufacturer warranty. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B016VIOIZC | | Best Sellers Rank | #28,679 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #3 in Compressed Air Regulators | | Brand | PneumaticPlus | | Brand Name | PneumaticPlus | | Customer Reviews | 4.2 out of 5 stars 32 Reviews | | Global Trade Identification Number | 00841693110030, 08416931100306 | | Included Components | Bracket | | Manufacturer | PneumaticPlus | | Material | Die-Cast Aluminum | | Material Type | Die-Cast Aluminum | | Model | PPR3-N02BG | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | PPR3-N02BG | | Thread Style | Npt | | Thread Type | Npt | | UPC | 841693110030 | | Unit Count | 1 Count | ## Product Details - **Brand:** PneumaticPlus - **Global Trade Identification Number:** 00841693110030, 08416931100306 - **Material:** Die-Cast Aluminum - **Thread Type:** Npt - **UPC:** 841693110030 ## Images ![PneumaticPlus PPR3-N02BG High Flow Air Pressure Regulator, 1/4" NPT - Image 1](https://m.media-amazon.com/images/I/71CXZIg5DLL.jpg) ![PneumaticPlus PPR3-N02BG High Flow Air Pressure Regulator, 1/4" NPT - Image 2](https://m.media-amazon.com/images/I/614adXGKXcL.jpg) ![PneumaticPlus PPR3-N02BG High Flow Air Pressure Regulator, 1/4" NPT - Image 3](https://m.media-amazon.com/images/I/71VrfL9uTSL.jpg) ![PneumaticPlus PPR3-N02BG High Flow Air Pressure Regulator, 1/4" NPT - Image 4](https://m.media-amazon.com/images/I/71JtwpiXxaL.jpg) ![PneumaticPlus PPR3-N02BG High Flow Air Pressure Regulator, 1/4" NPT - Image 5](https://m.media-amazon.com/images/I/71n3QKrQr4L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality product for controlled PSI *by E***M on May 3, 2026* Worked as advertised and allowed for enough CFM to blow out my sprinklers while maintaining safe line pressure. ### ⭐⭐⭐⭐⭐ Updated: 2 months later it's leaking air *by M***W on October 30, 2023* Update: I got in touch with Pneumatic Plus support which diagnosed the problem with me and sent a replacement.

I've put a female coupling on the output, so to set it I plug in my inflator (with gauge) and dial in the pressure I want, then remove the inflator and replace it with a T, two hoses, and two Haltec H-5265 chucks to two tires. This lets me air up two tires at a time relatively unattended and make sure they all have the same end pressure after off-roading (15->50psi), plus makes it easy to bring up the pressure further in the rear two tires when needed for heavy towing (50->80psi). I've only used it a handful of times at this point, but it's holding up well so far, including being put loose in a bag with other air-up parts and not handled particularly carefully. Since I'm using a simple onboard air system I don't have an air filter and dryer upstream of this regulator, so I don't know how long it will last before the lack of filtering causes any problems, but no issues yet. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/70110743-pneumaticplus-ppr3-n02bg-high-flow-air-pressure-regulator-1-4](https://www.desertcart.tn/products/70110743-pneumaticplus-ppr3-n02bg-high-flow-air-pressure-regulator-1-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-13*
