Legris 3606 12 00 Push-to-connect Union Straight Fitting

Product Description

The LEGRIS 3606 12 00 is a push-to-connect union straight tube fitting designed to join two lengths of tubing in a single inline connection. Constructed from nickel-plated brass, this fitting accepts 12mm outside diameter tubing and is rated to a maximum working pressure of 435 psi. It is compatible with both liquid and gas service, making it suitable for a wide range of pneumatic and fluid distribution applications. The FKM O-ring provides reliable sealing performance across a broad service temperature range. Trade professionals install this fitting in compressed air lines, instrumentation tubing, and other fluid control systems where a tool-free, push-in tube connection is required.

This fitting is intended for use in industrial and commercial applications where 12mm OD tubing is routed through pneumatic controls, process equipment, or fluid handling systems. It is equally suited to new installations and maintenance replacements. The straight union configuration allows inline splicing or extension of existing tube runs without soldering, threading, or compression tools. Its compact overall length of approximately 50mm keeps installation envelopes tight in panel and enclosure work.

Compatibility

Designed for use with 12mm outside diameter tubing in liquid and gas service applications per LEGRIS push-to-connect fitting specifications.

Installation Notes

Installation is performed by inserting clean, cut-square tubing into the fitting body until it seats against the internal stop. Ensure the tube end is free of burrs and debris before insertion to maintain seal integrity. Shut off and depressurize the system fully before disconnecting or replacing fittings in a live line. A licensed pipefitter, pneumatic technician, or instrumentation technician typically performs this work in regulated commercial or industrial environments.
