Coyote Gear offers several types of high quality stainless steel weld bung couplings. Class 150 for low pressure jobs and class 3000 for high pressure builds. We carry 304 stainless because it provides great value and 316 for those situations where you need optimal corrosion resistance.
Our NPT bungs comply with ASA B16.3 and ASA B2.1 manufacturing standards. These standards create a consistent product that welds up the same each time with threads that NPT fittings will thread into properly.
