The Series C0304-C Flareless Bite Type Tube Compression Cap Nut, made from high-quality carbon steel, is an essential component used to secure tube connections in fluid and gas systems. Designed for use with flareless bite-type tube fittings, this cap nut is tightened onto the tube fitting to ensure a leak-proof seal by compressing the ferrules onto the tubing. The cap nut’s reliable design makes it ideal for applications where high pressure and vibration resistance are critical, such as in hydraulic systems, oil and gas, and industrial machinery. Its durable construction ensures long-lasting performance and helps maintain the integrity of the system, preventing leaks and ensuring safe fluid or gas transfer.
