These fittings are made from top-quality titanium, offering an impressive strength-to-weight ratio, chemical inertness, and durability even in extreme conditions. With options available in both British Standard Pipe (BSP) and National Pipe Thread (NPT) configurations, Paul Tube Fittings guarantees compatibility with systems worldwide. Perfect for aggressive chemical, marine, and high-purity applications, these fittings deliver leak-proof performance, a long service life, and dependable reliability. All products adhere to international standards for safety, dimensional accuracy, and mechanical integrity.
The Titanium BSP/NPT Fittings from Paul Tube Fittings are crafted from premium titanium grades like Grade 2 (commercially pure) and Grade 5 (Ti-6Al-4V). These materials boast excellent corrosion resistance against chlorides, seawater, and harsh chemicals. Titanium is known for its high strength-to-weight ratio, low density, and tensile strength that ranges from 344 MPa (Grade 2) to 900 MPa (Grade 5). These fittings are non-magnetic, biocompatible, and show remarkable resistance to thermal expansion. Their threaded designs are meticulously machined to ensure leak-tight connections, making them perfect for high-pressure and high-temperature applications in corrosive settings.
