QDB10 Torch To Hose Quick Connect Set For Welding Torch With Check Valves

Product Information

About

Universal 9/16” B-Thread Design for Broad Oxy-Fuel CompatibilityPrecision-machined standard 9/16" B-thread ports fit most welding/cutting torches and dual-gas hoses. Physical interlock color-coded structure (green for oxygen, red for fuel) blocks cross-gas mismating entirely, eliminating dangerous mixed-gas combustion risks
Industrial-Grade Pressure Ratings for Stable High-Temp OperationCertified to industry safety standards: 29 PSI max working pressure for fuel lines, 145 PSI for oxygen circuits. Maintains consistent gas delivery under high heat and heavy workloads to secure reliable daily workshop performance
Built-In Check Valves with Instant Gas Shutoff Upon DisconnectionIntegrated precision one-way backflow prevention valves cut gas flow immediately when couplings separate. Rigorously airtight tested to fully isolate oxygen and fuel channels, stop flashback, backfire and hazardous reverse gas migration
One-Touch Quick Connect & Disconnect to Boost Job EfficiencyUser-friendly plug-and-lock design cuts assembly time drastically. Simply align and press fittings until the colored sleeve locks; pull back the color collar for fast release. Always perform a full leak test post-installation for safe ignition
Solid Precision-Forged Brass Body for Extreme LongevityConstructed from high-grade machined brass with superior corrosion and oxidation resistance. Withstands frequent plug/unplug cycles, dust, welding fumes and dirty workshop environments to extend service life under heavy industrial use
Standardized Periodic Inspection Guidelines for Long-Term Safety ComplianceMandate routine leak checks every six months for regular use; increase testing frequency if exposed to contaminants or after flashback incidents. Remember to close main gas sources fully after work and store fittings properly to avoid thread and seal damage
