IS Series Israel Type Pneumatic Quick Couplings

IS Series Israel Type Quick Couplings for Pneumatic Lines

IS Series Israel type pneumatic quick couplings are manually operated connectors for joining compressed-air lines and pneumatic equipment. The IS20 range uses a 1/4-inch body and offers several socket and plug configurations, making it suitable for installations that require convenient connection and disconnection. Although its plug profile resembles the IN20 series, the supplied specifications state that the two are not interchangeable.

Locking Structure and Connection Configurations

The IS20 model features four stainless steel locking balls and a sleeve-operated connection design. Its listed rated pressure is 2.0 MPa, with a temperature range of -10°C to +70°C.

● Socket options: Female thread (SF), male thread (SM), and hose barb (SH).

● Plug options: Female thread (PF), male thread (PM), and hose barb (PH).

● Materials: Brass, carbon steel, and stainless steel SUS303/304 are listed in the ordering code.

● Sealing: NBR is specified as standard; FKM may be considered for suitable higher-temperature applications.

Check the exact model and material code when ordering replacement components.

Applications in Industrial Compressed-Air Systems

IS Series quick couplings can be used with pneumatic tools, workshop air lines, and industrial equipment where operators need to connect or disconnect air hoses during setup or maintenance. Select the body size and connection type to match the equipment and hose arrangement.

Installation and Compatibility Checks

Before installation, verify the matching IS-series plug and socket, thread standard, and hose inner diameter. Secure threaded joints with a suitable sealing method, then pressurize the system gradually and inspect for leakage. Always isolate the air supply and release residual pressure before disconnection.

Important: The product image uses both PT thread coding and NPT labels in its dimensional tables. Confirm the required thread standard with FOKCA before placing an order, and do not assume IS20 plugs will fit IN20 couplings.
