Western Enterprises QDB33 Quick Connect Regulator-to-Hose Brass Inert Gas 5/8"-18 RH

The Western Enterprises QDB33 Quick Connect provides secure, fingertip-operated connections between inert gas regulators and hoses for B-size welding equipment. This brass-constructed fitting delivers reliable gas flow with instant disconnection capability for TIG welding and plasma cutting applications.

Engineered with a spring-loaded locking mechanism, this quick connect achieves gas-tight seals that respond to simple fingertip pressure. The double seal socket connection provides enhanced safety protection, while the demand valve on the supply side creates a positive seal when disconnected. Color-coded blue for inert gas identification, it prevents accidental gas mixing and ensures proper service identification in multi-gas shop environments.
