JIS Fittings

Product catalog summary

Overview
Parker Hannifin Corporation's Tube Fittings Division provides a comprehensive catalog of Japanese Industrial Standard (JIS) fittings, primarily used as hose adapters for equipment manufactured in Japan and Korea. These fittings are designed with 30° flare and 60° cone connections and typically use BSP threads.

Specifications
The JIS fittings include various types such as male connectors, plugs, caps, elbows, and unions. They are available in different sizes and configurations, including 30° flare/BSPT and 60° cone/BSPT connections. The fittings are manufactured from hot forged construction for shaped adapters and cold drawn barstock for straight adapters.

Thread Standards
The fittings use BSPP (ISO 228-1 G, JIS B 0202) and BSPT (ISO 7/1, JIS B 0203) thread forms. Each fitting is stamped with "JIS" for identification.

Design and Construction
JIS adapters are designed with BSPP and BSPT port ends and two styles of hose ends: T4 (30° flare, BSPP threads) and P4 (60° cone, BSPP threads). The fittings are compatible with Parker hose ends such as UT, GU, G1, G2, and FU.

Dynamic Pressure Ratings
The dynamic pressure ratings for these fittings range from 3,000 to 5,000 PSI, depending on the size and type of fitting.

Material Specifications
Standard material specifications are detailed in Table U1 in the appendix section of the catalog.
