Elkhart Products STLSELL-34 Copper Long Sweep Street Elbow

Product Description

The ELKHART PRODUCTS STLSELL-34 is a copper long sweep street elbow designed for ACR (air conditioning and refrigeration) tubing systems. This fitting accepts 7/8 inch OD ACR tubing, which corresponds to the standard 3/4 inch nominal size. The long sweep design provides a gradual directional change that reduces turbulence and pressure drop in refrigerant lines compared to standard elbows. Licensed HVAC and refrigeration technicians use this type of fitting when routing suction or liquid lines through tight spaces where a smooth bend is required to maintain system efficiency.

This street elbow is intended for use in residential and light commercial HVAC and refrigeration installations. The street configuration — one male and one female end — eliminates the need for a separate coupling when changing direction from a male-end connection point. It is suited for refrigerant line sets, ACR piping assemblies, and similar applications where copper sweat fittings are specified. Installers working on split systems, packaged units, or refrigeration equipment will find this fitting useful wherever a long-radius directional change is needed in copper tubing runs.

Key Features

• Long sweep design reduces turbulence and minimizes pressure drop in refrigerant lines
• Street elbow configuration with one male and one female end eliminates the need for an additional coupling
• Sized for 7/8 inch OD ACR copper tubing (3/4 inch nominal)
• Copper construction compatible with standard sweat (solder) joining methods
• Designed for ACR refrigerant line applications in HVAC and refrigeration systems

Compatibility

Designed as an OEM-style copper sweat fitting for use with 7/8 inch OD ACR copper tubing in residential and commercial HVAC and refrigeration piping applications.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician in accordance with applicable mechanical codes. Recover and recover all refrigerant from the system before cutting or modifying any refrigerant lines. Clean and deburr tubing ends before fitting and apply appropriate flux prior to soldering. Purge lines with dry nitrogen during the brazing process to prevent internal oxidation scaling.
