Smc Pneumatics KQ2E05-00A Bulkhead Union Fitting 3/16 in Od

Product Description

The SMC PNEUMATICS KQ2E05-00A is a push-to-connect bulkhead union tube fitting designed for pneumatic and fluid line installations requiring a panel or bulkhead passthrough. Built from brass with polybutylene contact components, this fitting accepts 3/16 inch OD tubing and connects on both sides without tools, using a simple push-in locking mechanism. It is rated to 145 psi maximum working pressure and carries RoHS compliance. Plumbers, pipefitters, and pneumatic system technicians install this type of fitting where a tube line must pass cleanly through a panel, enclosure wall, or manifold plate.

This bulkhead union fitting suits light industrial, pneumatic control, and fluid distribution systems operating within its rated temperature and pressure limits. The 9/16-18 UNF thread pattern is standard for panel-mount push-to-connect fittings in this size class. It is appropriate for use in residential, commercial, and light industrial environments where a clean, leak-free bulkhead tube connection is needed. The push-to-connect design speeds installation and allows tubing to be released and reinserted during commissioning or maintenance without replacing the fitting.

Key Features

• Push-to-connect design on both ends - no tools needed for tube insertion
• Bulkhead union body allows tube lines to pass through panels or enclosure walls
• Rated to 145 psi maximum working pressure
• Operating temperature range: 23 degrees F to 140 degrees F
• Brass and polybutylene construction for durability in pneumatic and fluid service
• RoHS compliant

Compatibility

Designed as an OEM-style replacement or direct-install bulkhead union fitting for pneumatic and fluid tubing systems using 3/16 inch OD tubing with a 9/16-18 UNF panel-mount thread.

Installation Notes

Depressurize and isolate the system before removing or installing any tube fitting. Ensure the panel hole is sized and finished to the fitting's thread specification before threading in the bulkhead body. Push-to-connect tube ends must be cut square and free of burrs for a proper seal. Verify that tubing material and system fluid are compatible with brass and polybutylene before installation.
