Model HA Inferno® air-fuel quick connect swirl tip has a specially-designed insert that delivers reliable swirl combustion performance every time. It provides a consistently hotter flame that will engulf and wrap around the work-piece for maximum efficiency. It is constructed from thick and strong 304 stainless steel tube stock designed to be durable and long-lasting. The tip works and integrates with today's existing quick-connect air-fuel handles allowing contractors to simply and quickly connect to their existing torch handles using acetylene.
