Shop Superlok SFC Stainless Tube - Female NPT
Series SFC Straight Tube x Female NPT Adapters in 316 stainless steel (316SS) are robust fittings designed to connect straight tubing to female NPT (National Pipe Thread) threaded connections in hydraulic and pneumatic systems. These adapters are made from 316SS, known for its excellent corrosion resistance, making them ideal for use in harsh environments like chemical processing, marine, and food industries. The female NPT side features tapered threads that provide a tight, secure seal when screwed into NPT-compatible components, ensuring a leak-proof connection. The tube side connects to straight tubing, often made from materials such as steel, copper, or aluminum, used to transport fluids or gases. The tube is securely inserted into the adapter, with a compression fitting ensuring a durable and leak-free connection. NPT fittings are highly valued for their ability to handle high-pressure applications, providing reliable and efficient fluid system connections.
