QC-RHPRSP - Regulator-to-Hose Quick Connect Set with Check Valves

Advanced Gas Safety and Efficiency

The Smith Equipment QC-RHPRSP Quick Connects with Check Valves represent a premium solution for professional oxy-fuel operators seeking both efficiency and enhanced safety in their gas distribution systems. Designed specifically for the interface between gas regulators and supply hoses, this set streamlines the setup and teardown process of welding and cutting outfits without compromising on system integrity. The inclusion of high-quality check valves within the connector body is a critical engineering feature, designed to prevent the reverse flow of gases—a primary precursor to dangerous mixed-gas situations that can lead to flashbacks.

Robust Construction and Compatibility

Manufactured from high-grade brass, these connectors are engineered to withstand the rigors of industrial environments, resisting corrosion and mechanical wear. The set includes components for both oxygen and fuel gas lines, clearly distinguished by industry-standard color coding (green for oxygen, red for fuel) and thread direction (right-hand for oxygen, left-hand for fuel) to prevent cross-connection errors. The fittings utilize standard B-size (9/16"-18) threads, making them universally compatible with the vast majority of industrial regulators and hoses, including the Smith Protogo portable systems. The precision-machined locking mechanism ensures a positive seal that engages instantly and holds securely under pressure.

Operational Benefits

For maintenance, repair, and operations (MRO) professionals, time is a valuable resource. The QC-RHPRSP set eliminates the need for wrenches during daily equipment mobilization. Once the initial installation of the bodies and pins is complete, operators can connect or disconnect hoses in seconds. This is particularly advantageous for mobile repair units, field fabrication teams, and workshops where equipment must be stored securely at the end of each shift. By integrating the check valve into the quick connect, Smith Equipment reduces the overall length and weight of the assembly compared to using separate devices, maintaining a streamlined profile at the regulator outlet.
