1/4 in to 5/16 in push-fit reducer

This Legris push-fit reducer connects a 1/4 in outer-diameter tube to a 5/16 in tube stem in compressed-air systems. The fiberglass-reinforced nylon body withstands 290 psi at up to 176 °F. Each fitting measures 1 5/8 in overall length and installs without tools or thread sealant. Supplied in a pack of 10 pieces.

Suitable for pneumatic lines needing a quick size

Technicians joining metric and imperial tubing or repairing existing air circuits will find this reducer convenient. It is not for hydraulic circuits, fuel lines or any fluid other than compressed air. Installers who need threaded connections, higher temperature ratings or metal bodies should select a different fitting type.

290 psi maximum operating pressure

The 290 psi pressure rating is the single figure that determines whether this reducer matches the system design. Verify the circuit pressure stays below this limit before specifying the part.

Questions about this item

How does the 290 psi pressure rating hold up when the fitting is actually installed in a compressed-air line?

The fitting is rated for a maximum operating pressure of 290 psi, so it will safely handle typical workshop air systems that run at or below that level.

What does the push-to-connect interface mean for the 1/4 in and 5/16 in tube ends in daily use?

The push-to-connect end accepts 1/4 in OD tubing with a simple push, while the stem end inserts into a 5/16 in push-fit port, giving a tool-free, leak-tight joint on both sizes.

Will the 1 5/8 in overall length and black fiberglass-reinforced nylon body fit inside a standard pneumatic control panel?

At 1 5/8 in long and made from black fiberglass-reinforced nylon, the reducer is compact enough for tight panel cut-outs and resists vibration and heat up to 176 °F.
