JIS Hydraulic Adapters
JIS(Japanese Industrial Standard) Hydraulic Adapters in the early 1990s, they are used in the market of Japan and Korea equipment as hose adapters. JIS adapters are designed with 30°flare and 60°cone connections and typically incorporate BSP threads. JIS adapters are designed with BSPP JIS B2351 o-ring seal and BSPT port taper thread seal ends and two styles of JIS hose adapter ends.
