8 mm Tube Brass Swivel Elbow

The Legris 3609 fitting connects an 8 mm tube to a 1/8 BSPT thread in a 90 degree swivel elbow. It is intended for pneumatic or fluid circuits that require a compact directional change at the connection point.

Thermals Noise and Power Draw

The nickel plated brass body handles a maximum pressure of 435 psi and operates from -4 to 302 degrees F. The swivel action allows alignment without stressing the tube during temperature cycling.

Hex 11 mm Installation Detail

An 11 mm hex permits secure tightening with a standard spanner while the swivel nut locks the orientation. California Proposition 65 warnings apply because the brass alloy contains listed chemicals.

Questions about this item

How do I install the 8mm tube into the swivel elbow without damaging the fitting?

Push the 8mm tube firmly into the nickel-plated brass body until it seats against the internal stop, then tighten the 1/8 BSPT male thread with an 11 mm spanner; the common mistake is over-torquing the swivel nut before the tube is fully inserted.

What maintenance or replacement will the nickel-plated brass swivel elbow need over time?

Inspect the O-ring seal and thread engagement periodically; replace the fitting if the swivel action stiffens, the 8mm tube grip loosens, or corrosion appears on the nickel-plated brass surfaces.

Which limit appears first when the elbow runs continuously at its 435 psi rating?

The 302 °F temperature ceiling is reached before the 435 psi pressure limit under sustained high-temperature operation.
