Unequal Union 1/8x1/4 Inch

This Legris 3106 53 56 union joins 1/8 inch tubing to 1/4 inch tubing using push-to-connect ends on both sides. The pack contains ten black fittings made from fiberglass-reinforced nylon for air-line plumbing. It suits installers who need a quick, tool-free transition between two different tube diameters.

Sustained Pressure Performance

The fitting is rated for a maximum operating pressure of 290 psi and a maximum operating temperature of 176 degrees F. These limits apply to continuous service in compressed-air systems. The fiberglass-reinforced nylon body maintains its grip and seal under prolonged pressurised conditions without the need for thread sealant.

Thermals Noise and Power Draw

As a passive pneumatic component the union generates no noise, draws no power and produces no heat of its own. Its temperature simply follows the surrounding air and the compressed-air stream up to the 176 degree F rating. The black finish does not alter thermal behaviour in normal workshop environments.

Questions about this item

Does the fitting get hot or noisy when compressed air runs through it continuously at 290 psi?

The fiberglass-reinforced nylon body stays at ambient temperature and has no moving parts, so it runs silently even at the maximum 290 psi operating pressure.

What tube sizes must I already have to connect both ends of this union?

You need 1/8 in outer-diameter tubing for side A and 1/4 in outer-diameter tubing for side B; both ends use push-to-connect ports.

Will the 1 5/16 in overall length fit alongside older 1/4 in push-fit fittings in the same manifold?

Yes, the 1 5/16 in length matches standard spacing for 1/4 in push-fit unions, so it aligns with existing fittings in the same line.
