Copper W03050 1-3/8" 45° Elbow Fitting Copper

About this item

The 1-3/8 inch copper 45 degree elbow in this listing, part W03050, is sold as a single fitting. This size appears on refrigeration and HVAC lines, which are measured by outside diameter. It also matches the OD of 1-1/4 inch nominal plumbing tube.

Is 1-3/8 inch the pipe size or the outside diameter?

On copper it is usually the OD. Measure across the outside of your tube, and if it reads 1-3/8 inch, this fitting matches. Check the listing for the connection type.

• Use: offsets on large supply, hydronic or refrigeration lines.
• Heat: larger fittings need even heating so the solder or brazing alloy flows all the way in.
• Quantity: one elbow.
• Code: refrigerant work may require certification, so check local rules.
