Copper ProPress 45° street elbow
This 1-1/4-inch copper fitting joins a press-fit tube end to an FTG socket at a forty-five degree angle. It is intended for potable-water systems where a compact directional change is required. The EPDM O-ring provides the seal without solder or flux. The fitting conforms to ASTM B75 and ASTM B88 material standards.
Sustained pressure and temperature performance
The assembly is rated for a maximum operating pressure of 200 psi and a maximum operating temperature of 250 degrees F. These limits apply to continuous service rather than brief test spikes. Copper construction resists scaling and corrosion over long periods in hot-water circulation loops. The press joint maintains integrity through thermal cycling without the fatigue that can affect threaded connections.
Press-fit copper system constraints
The ProPress connection method requires a compatible press tool and jaw set matched to the 1-1/4-inch tube size. Installers must verify that the tubing meets ASTM B88 dimensions for a reliable crimp. The fitting is not designed for gas, compressed-air or hydronic-glycol systems beyond the stated water ratings. Local codes may impose additional restrictions on press-fit joints in concealed locations.

Questions about this item
How much pressure and heat can the ProPress 77063 street elbow handle in continuous service?
The copper fitting with EPDM O-ring is rated for a maximum operating pressure of 200 psi and a maximum operating temperature of 250 Degrees F, so it will maintain its seal during all-day hot-water circulation.
What tools and pipe preparation are required before pressing this 1-1/4" street elbow?
You need a compatible ProPress press tool and jaws for 1-1/4" copper tube, plus a tubing cutter and deburring tool to prepare clean, square ends on Type K, L or M copper pipe meeting ASTM B88.
Will this 45-degree street elbow join directly to an existing 1-1/4" copper fitting without an extra coupling?
Yes, the street design gives a press-fit socket on one end and a plain FTG end on the other, allowing the FTG end to slide into another 1-1/4" ProPress fitting or copper adapter for a direct connection.
