Pipe Fittings 3 Features All ˜ttings have a high-quality appearance. Every ˜tting is marked with manufacturer™s name for easy source tracing. Male threads are capped for protection. Straight ˜ttings are manufactured from quality bar stock for strength. NPT threads are based on requirements of ASME B1.20.1 and SAE AS71051. Burr-free internal surfaces. Shaped ˜ttings are manufactured from forgings. Smooth thread ˚anks provide optimum sealing and minimize galling. Angles on elbows, tees, and crosses are rigidly controlled for accurate piping layout. Marking identi˜es material, heat code for material traceability, and ISO end connection. Temperature Ratings System temperatures may be limited by the thread sealant or, when applicable, the gasket or O-ring material.
