SKU CH-BX4F-FN8Q6

Copper 45-degree street elbow for potable water systems with press-fit and FTG ends rated to 200 psi and 250 degrees F

  • Press-fit copper elbow installs without soldering
  • 45-degree street design routes pipe around obstacles
  • EPDM O-ring seals potable water to 200 psi
  • Rated for 250 °F maximum operating temperature
  • Meets ASTM B75 and ASTM B88 standards

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.
