Smc Pneumatics KQ2H11-35AS Push-to-connect Fitting 3/8 Od

Product Description

The SMC PNEUMATICS KQ2H11-35AS is a push-to-connect tube fitting connector designed for fast, tool-free pneumatic line assembly. It accepts 3/8-inch OD tubing and connects to 1/4-inch NPT threaded ports, making it a practical choice for building or extending compressed air circuits without soldering or compression tooling. The fitting is constructed from brass with polybutylene components and is rated for a maximum working pressure of 145 psi. It suits applications where reliable, leak-resistant connections are needed in moderate-pressure pneumatic systems. Licensed pipefitters, pneumatic system technicians, and industrial maintenance trades install this type of fitting in both new builds and service work.

This fitting is suited for use in compressed air distribution systems, pneumatic controls, and fluid handling lines that operate within the rated pressure and temperature range. Typical installations include inline connections where tubing runs need to be extended, rerouted, or terminated at a threaded port. The compact overall length of approximately 0.99 inches (25.10 mm) makes it a practical choice in tight panel or manifold layouts where space is limited.

Key Features

• Brass and polybutylene construction for moderate-pressure service
• Rated to 145 psi maximum working pressure
• Operating temperature range of 23 degrees F to 140 degrees F
• RoHS compliant materials

Compatibility

Designed as an OEM-style replacement or service fitting for pneumatic and compressed air systems using 3/8-inch OD tubing terminated at 1/4-inch NPT threaded ports.

Installation Notes

Installation is typically performed by pipefitters, pneumatic system technicians, or industrial maintenance trades. Depressurize and lock out the pneumatic circuit completely before removing or installing any fittings. Verify that the NPT thread is clean and apply appropriate thread sealant per system requirements before engaging the fitting. Do not exceed the rated working pressure of 145 psi or the maximum temperature of 140 degrees F in service.
