Legris 3183 08 00 Plug-in Run Tee 5/16 Inch Od Nylon

Product Description

The LEGRIS 3183 08 00 is a push-to-connect plug-in run tee fitting designed for fast, tool-free tube connections in pneumatic and fluid-handling systems. Constructed from nylon, this fitting accepts 5/16 inch outside diameter tubing and is rated for up to 290 psi working pressure. The run tee configuration routes flow straight through two ports while adding a branch outlet, making it a practical choice for inline branching without cutting into existing hard plumbing. HVAC technicians, plumbers, and industrial maintenance pros use push-to-connect fittings like this one to speed up installations and reduce the risk of connection errors on the bench or in the field.

This fitting is suited for light to medium-pressure pneumatic lines, instrumentation tubing, and general-purpose fluid distribution applications. It is commonly used in equipment panels, control systems, and compressed air distribution where 5/16 inch OD tubing is the standard line size. The nylon construction keeps weight low and resists corrosion in environments where metal fittings would be subject to oxidation or chemical attack. It is sold in single-unit quantities, making it easy to source for maintenance and repair work as well as new installations.

Installation Notes

Depressurize and de-energize the system completely before removing or installing any pneumatic fitting. Verify tubing is cut cleanly and squarely with no burrs before insertion, as ragged cuts prevent proper seating and can cause leaks. Tube insertion should be firm until a positive stop is felt, confirming the collet has engaged. After installation, restore pressure gradually and inspect all connections for leaks before returning the system to service.
