1501-20-16-FG : OneHydraulics 90-Degree Steel Adapter, 1-1/4-11-1/2 (-20) Male NPTF x 1-11-1/2 (-16) Female NPSM Swivel, 2000psi

The Series 1501 90-Degree Angled Male NPTF x Female NPSM swivel adapters are high-quality carbon steel fittings designed for secure, leak-free connections in hydraulic systems. These adapters feature a 90-degree angle, making them ideal for efficiently routing hoses and pipes in tight spaces. One end has a male NPTF (National Pipe Tapered Fuel) thread, which provides a precise seal through the tight fit of its threads, while the other end features a female NPSM (National Pipe Straight Mechanical) thread, which is designed for a metal-to-metal seal when connected. The key difference between NPTF and NPSM is that NPTF threads are designed for a leak-tight seal without the need for sealant, while NPSM threads are used in mechanical applications and require a gasket or sealant to ensure a leak-free connection. The swivel feature on these adapters allows for flexible installation, making them ideal for high-pressure fluid transfer systems. Made from durable carbon steel, these adapters provide strength, reliability, and long-lasting performance in demanding industrial environments.
