Overview

The NSi Industries LDM-31 Liqua-Seal Connector is a straight, 1" NPT threaded connector designed for reliable fluid connections in industrial applications. Constructed from durable die-cast zinc, this connector ensures long-lasting performance and corrosion resistance in harsh environments. The 1" NPT threading provides a secure, leak-proof connection, while the insulated design enhances safety and efficiency. This connector meets industry standards for cold impact and simulated hammer blow, ensuring durability in demanding conditions. It is unaffected by exposure to detergents, cleaners, sanitizers, cutting fluids, wiring pulling compounds, and marine environments, making it ideal for food processing plants, industrial systems, and HVAC applications. The LDM-31 is listed/certified by UL (File #E23018) and CSA (File #LR52391), conforming to CSA 22.2 #227.2 & #227.3, ANSI/UL 514B-1988, and watertight requirements of NEMA Type 4 and Type 6 enclosures. It is suitable for hazardous locations including Class I Div. 2, Class II Div. 1 & 2, and Class III per NEC. The connector’s thermoplastic body (black) and nitrile O-ring (blue) provide a temperature rating of -40°C to 105°C, with a flammability rating of UL 94-V2.
