Smc Pneumatics KQ2E12-00A Bulkhead Union Fitting 12mm

Product Description

The SMC PNEUMATICS KQ2E12-00A is a push-to-connect bulkhead union tube fitting designed for pneumatic plumbing and fluid handling installations. Built from brass with polybutylene components, this fitting accepts 12mm outside diameter tubing and allows technicians to route lines through panels, enclosures, or bulkheads without tools for tube insertion. It is rated to 145 psi maximum working pressure and carries RoHS compliance. Licensed HVAC technicians, industrial plumbers, and pneumatic system installers use this type of fitting when routing compressed air or compatible fluid lines through a fixed partition while maintaining a secure, leak-resistant connection on both sides.

This fitting is suited for residential and light commercial pneumatic systems, control panel builds, and compressed air distribution where a through-panel tube connection is required. The M22x1 thread engages a standard panel or manifold port, and the push-to-connect design on both ends speeds up tube termination during installation or service. It is appropriate for systems operating within the rated temperature window, such as equipment rooms, mechanical spaces, and light industrial enclosures where 12mm OD tubing is standard practice.

Key Features

• Push-to-connect design on both ends for tool-free tube insertion and removal
• Bulkhead configuration allows through-panel routing of pneumatic lines
• Brass body with polybutylene components for durability and media compatibility
• Rated to 145 psi maximum working pressure
• M22x1 thread for secure panel or manifold mounting
• RoHS compliant construction

Compatibility

Designed as an OEM-style push-to-connect bulkhead fitting for pneumatic systems using 12mm outside diameter tubing with an M22x1 threaded panel port.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or licensed plumber. De-pressurize and isolate the system completely before removing or installing any fittings. Verify the panel or manifold bore matches the M22x1 thread before installation, and confirm the tubing outside diameter is 12mm before seating the tube into the push-to-connect end. Do not exceed the 145 psi maximum working pressure or operate outside the rated temperature range of 23 to 140 degrees F.
