Legris 3806 04 00 Union Straight Tube Fitting 5/32 in Od

Product Description

The LEGRIS 3806 04 00 is a push-to-connect union straight tube fitting designed for tube-to-tube connections in pneumatic and fluid-handling systems. It accepts tubing with a 5/32-inch outside diameter and holds a maximum working pressure of 435 psi. The body is constructed from stainless steel, and the seals use FKM o-rings, making this fitting suitable for service in environments where chemical resistance and temperature stability are required. Operating temperatures range from -4 degrees F to 248 degrees F. Licensed plumbers, pipefitters, and pneumatic system technicians typically specify and install this fitting in instrumentation, control, and process lines.

This fitting is used in tube-to-tube inline connections where a tool-free, push-to-connect union is needed. It is well-suited for residential and light commercial pneumatic control systems, instrumentation tubing runs, food-processing lines, and other applications requiring stainless steel construction with certified compliance to food-contact and hazardous-area standards. The straight union configuration allows a direct, in-line connection without change of direction, keeping plumbing layouts clean and compact.

Compatibility

Designed for use with 5/32-inch OD tubing in push-to-connect pneumatic and fluid-handling systems. Consult system documentation to confirm tubing material and pressure rating compatibility before installation.

Installation Notes

Installation does not require tools for tube insertion — cut tubing squarely and deburr the end before pushing into the fitting body until it seats fully. To remove tubing, depress the collet release ring while pulling the tube free. Power down or depressurize the system completely before servicing any fitting in a pressurized line. Follow applicable codes and the fitting manufacturer's pressure-temperature derating guidelines when used in elevated-temperature or high-cycle applications.
