If you're working on a project that needs a threaded connection for tubing or hoses, these half couplings (bungs) are the perfect item for you. Our Class 150 fittings are cast from 316 stainless steel with female national pipe threads for a solid leak-proof connection. One end of these half couplings have a flat surface with a bevel for welding, while the other (receiving) end have a tapered lip for ease of threading. Made of 316 stainless steel, a steel that is low in carbon/free-iron content, these fitting are perfect for applications where corrosion is a concern.

Popular applications include: Automotive, Marine, Power sports, Industrial, Manufacturing, Equipment, Hauling, Trailers, Snowmobiles, ATV's, UTV's, Hot Rods, Fuel Cells, Gas Tanks, Brewing, home brewing, beer making, wine making, etc

**We stock half coupling in sizes from 1/8" all the way to 6". See our other listings on Amazon!**
