JIS 30° Flare Hydraulic Fittings Union
THU G
JIS 30-degree Flare Hydraulic Fittings Male Adapter
JIS 30° Flare Hydraulic Fittings Unions are widely used for joining tubing in a hydraulic fluid and gas system, such as chemical processing systems, fuel delivery, fluid power and so on.
JIS 30-degree Flare Hydraulic Fittings Unions are made of stainless steel, one-piece straight adapter. They are designed with 30-degree taper seat metal to meatal sealing. Unions are for connection and disconnection of tube to achieve a free flow of liquid, gas. It is used as the diversion port in pipelines.
