Over that past year I have ordered and used many different Anderson fittings. This is one of them. Without exception, I have found Anderson fittings to be top quality. No fitting has ever failed me. The threads have all been excellently cut and are well within specification for NPT design. When wrapped with PTFE and tightened properly (not over-tight..) they never leak. The barbed shank is longer than some others and holds tightly to hose. Once again, when clamped properly there will never be a leak. The hex shape on the exterior is perfect for use with a typical open-end wrench. Nicely machined and finished.
