The Series 6574 Tee Adapter, featuring Male JIC x Female JIC Swivel x Female NPT connections, is a versatile hydraulic fitting commonly used as a gauge adapter for monitoring system pressure. The male JIC (Joint Industry Council) connection uses a 37-degree flare seat to create a strong, leak-free metal-to-metal seal, while the female JIC swivel end allows the fitting to rotate during installation, making assembly easier and preventing hose twisting. The third branch of the tee features a female NPT (National Pipe Tapered) port, which uses tapered threads to create a secure threaded connection for accessories such as pressure gauges, test hoses, or diagnostic equipment. By allowing a gauge or hose whip to be connected directly into a hydraulic line, the Series 6574 Tee makes pressure testing, troubleshooting, and system monitoring quick and convenient. Manufactured from durable materials for demanding fluid power applications, these adapters are widely used in hydraulic maintenance, diagnostics, and pressure monitoring systems.
