Smc Pneumatics KCE04-00 Bulkhead Union Fitting 4mm

Product Description

The SMC PNEUMATICS KCE04-00 is a bulkhead union push-to-connect tube fitting designed for routing pneumatic tubing through panels, enclosures, or partition walls. It accepts 4 mm outside diameter tubing and supports a maximum working pressure of 145 psi. The body is constructed of brass with polybutylene contact components, offering solid corrosion resistance in clean air and general fluid transfer applications. The push-to-connect design allows fast, tool-free tube insertion and secure retention without additional fittings or sealants. Licensed pneumatic technicians and industrial maintenance professionals are the primary installers of this fitting type.

This fitting is suited for pneumatic control systems, automation equipment, and fluid transfer lines where tubing must pass through a bulkhead or panel. The 4 mm tube OD size is common in compact pneumatic circuits used in light industrial, laboratory, and machine-building environments. Its RoHS-compliant construction makes it appropriate for applications with environmental material restrictions. The 42 mm overall length accommodates standard panel thicknesses encountered in control cabinet and machine frame installations.

Compatibility

Designed for use with 4 mm outside diameter push-to-connect pneumatic tubing in general-purpose pneumatic and fluid transfer systems.

Installation Notes

Installation is performed by pneumatic technicians or industrial maintenance professionals. Depressurize and isolate the pneumatic circuit completely before removing or installing any fittings. Insert tubing fully until seated to ensure a secure, leak-free connection. Verify the panel or bulkhead thickness falls within the fitting's clamping range before mounting.
