The VALUE COLLECTION 172H-4 is a Tip Number 4 oxy-acetylene heating elbow nozzle designed for medium-duty heating applications. Part of the 142T Series, this nozzle delivers a concentrated flame pattern suited for localized heating tasks such as pipe bending, thawing, and general metal heating. The elbow configuration positions the flame at an angle, giving the technician better access to tight or awkward work areas without repositioning the torch body. Weighing 0.5 pounds, it is a lightweight addition to a standard oxy-acetylene outfit. Licensed trade professionals working in plumbing, HVAC, and metal fabrication will find this nozzle a practical tool for everyday heating work.
The 172H-4 is intended for use with general purpose oxy-acetylene torches that accept 142T Series tips. It is well suited for residential and light commercial applications where medium-duty heating is required, including pipe work, soldering pre-heat, and structural steel heating. The elbow nozzle style is particularly useful when working in confined spaces, such as inside wall cavities or around existing mechanical equipment, where a straight tip would be difficult to aim accurately.
Designed for use with general purpose oxy-acetylene torches that accept 142T Series medium-duty heating tips.
Installation and use of oxy-acetylene heating tips should be performed by qualified welding or trade professionals familiar with compressed gas safety procedures. Always shut off both oxygen and acetylene supply valves at the cylinder before changing tips, and verify the nozzle is fully seated and hand-tight before lighting. Inspect the tip orifice for blockage or damage prior to each use. Follow all applicable local codes and OSHA standards governing the storage and use of compressed flammable gases on the job site.
