The ASME B16.11 A350 LF2 Threaded Cap is a high-pressure forged fitting designed for low-temperature and cryogenic pipe termination. Forged from fine-grained alloy steel, it maintains superior notch toughness down to -46℃. Precision internal NPT threads ensure a leak-proof seal without the need for welding. Rated for 2000 PSI, it is the industry standard for sealing branch ends, sampling points, and headers in LNG processing and arctic oil and gas facilities.
