Smc Pneumatics KCJ10-99 Push-to-connect Check Adapter

Product Description

The SMC PNEUMATICS KCJ10-99 is a push-to-connect check adapter fitting designed for inline flow control in pneumatic and fluid tubing systems. Constructed from brass and polybutylene, it accepts a 10 mm outside diameter tube and allows tool-free tube insertion while preventing reverse flow through its integrated check function. Rated to a maximum working pressure of 145 psi, this fitting is suited for compressed air lines, pneumatic circuit assemblies, and compatible fluid distribution applications. Licensed plumbers, pipefitters, and pneumatic system technicians typically install this fitting during panel builds or service calls where directional flow control is required at the tube connection point.

The KCJ10-99 is applicable in light industrial and commercial pneumatic systems where quick-connect fittings are used to simplify tubing runs and reduce assembly time. Its compact overall length of approximately 2.77 inches (70.40 mm) allows installation in tight manifold and panel layouts. The push-to-connect design is well-suited for environments where tubing is frequently removed and re-routed during maintenance or system reconfiguration. This fitting is compliant with RoHS standards, making it appropriate for projects with environmental material restrictions.

Key Features

• Push-to-connect design allows tool-free tube insertion and removal
• Integrated check function prevents reverse flow in the line
• Rated to 145 psi maximum working pressure
• Brass and polybutylene construction for durability in pneumatic service
• 10 mm outside diameter tube compatibility on both connection and stem
• RoHS compliant materials

Compatibility

Designed as an OEM-style push-to-connect check adapter fitting for pneumatic tubing systems accepting 10 mm outside diameter tubing at up to 145 psi working pressure.

Installation Notes

Installation of pneumatic fittings should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and lock out the system completely before removing or installing any fitting. Verify that tubing outside diameter matches the fitting specification before insertion, and ensure the tube is cut cleanly and squarely to achieve a proper seal. Do not exceed the rated maximum working pressure of 145 psi in service.
