The FAIRVIEW s6769-6b is a steel compression 90-degree elbow fitting designed to create a right-angle connection between a compression tube and a male pipe thread port. It connects a 3/8-inch OD tube to a 1/4-inch MPT male thread, making a 90-degree directional change in the line. Fittings like this are used in plumbing, HVAC, and refrigeration tubing runs where a hard turn is needed and space does not allow a bent tube. Installation is handled by plumbers, HVAC technicians, and pipefitters working with small-diameter steel compression systems.
This fitting is suited for residential and light commercial applications where a compact 90-degree transition is required between a compression tube line and a threaded port. It is commonly installed in gas appliance connections, instrumentation lines, and pneumatic or hydraulic control tubing where steel construction is required for pressure integrity and durability.
Designed as an OEM-style replacement or new-installation compression fitting for systems using 3/8-inch OD tubing with 1/4-inch male pipe thread connections.
A licensed plumber or qualified HVAC technician should install this fitting. Shut off all pressure to the line and depressurize the system before removing or installing any compression fitting. Hand-tighten the compression nut first, then snug with a wrench — avoid overtightening, which can crack or deform the ferrule. Apply thread sealant rated for the service type to the MPT threads in accordance with applicable codes such as the IPC or IFGC.
