QC-RHF-MSP - Protogo Oxygen Quick Connect Fitting - Regulator to Hose Male B-Size

Snap, Click, and Cut

Stop wasting valuable time wrestling with wrenches every morning. The Protogo Quick Connect Oxygen Fitting is built for welders who want to get straight to work. This "Reg to Hose" fitting allows you to instantly connect your oxygen line to your regulator with a simple push-to-connect action. No more cross-threading, no more hunting for the right wrench size, and no more worn-out brass nuts.

Designed with the standard B-Size (9/16"-18) threads you already use, this fitting screws directly into your setup. Because it's for Oxygen, it features the standard Right-Hand thread, keeping your gas lines safe and compliant. The solid brass construction means it can take a beating in the shop or on the truck. Whether you are breaking down your rig at the end of the day or swapping between different length hoses, this quick connect makes the process effortless.

Using quick connects also saves your gear. Constant tightening and loosening can strip regulator threads over time. With the Protogo QC system, you install the threaded ends once, and the quick-action coupler takes the wear and tear from then on. It’s a small upgrade that makes a massive difference in your daily workflow, giving you a professional, leak-free connection every time you hear that click.
