Push-Fit Wye Fitting for 8 mm Tubing
The Legris 3140 08 00 is a black push-fit wye fitting designed for air applications. It connects three tubes with an outside diameter of 8 mm or 5/16 in using push-to-connect ends on all sides. The body is made from brass and fiberglass-reinforced nylon. It is supplied as a pack of 10 for pneumatic system assembly.
Ready-to-Use Connection Without Sealant
Each fitting arrives with a push-to-connect mechanism that grips and seals the tube without the need for separate thread sealant or tools. This reduces installation time compared to threaded alternatives. The pre-assembled design ensures consistent sealing performance across all three ports during initial setup.
Limited to Specific Tube Diameter and Media
The fitting accepts only tubing with an 8 mm or 5/16 in outside diameter, so it cannot join larger or smaller lines without adapters. It is rated for air service only and is not intended for hydraulic fluids or potable water systems. Brass and nylon construction may limit compatibility with certain aggressive chemicals or high-temperature environments.

Questions about this item
Will the brass and reinforced-nylon body of the 3140 08 00 need periodic replacement?
The fitting is a single-piece push-fit component with no moving parts or serviceable seals; under normal pneumatic use it remains in place until the tubing is removed.
What is the first limit reached when the 8 mm push-fit connections run continuously under pressure?
The connection relies on the collet gripping the tube outer diameter; sustained pressure beyond the fitting's rated limit will cause tube release or leakage at the seal first.
How much heat does the brass and nylon union generate during all-day compressed-air operation?
The fitting itself produces no heat; it simply transmits the air temperature already present in the system.
